Rockbox

Can't load Rockbox from my SDHC 32 GB A-Data Turbo Class 6.
Get “ATA mount File not found”. Cowon FW loads well.

The OF ide_power_enable routine sets some GPIO _ENABLE bits to zero when enabling power and sets them to 1 when disabling power. This makes a difference of about 1 in 4066_ISTAT ( FS#9728 ) on my 30 gig iPod, which probably means saving about 0.75 mA. But if 1 is enable, why does enabling pins save power?

Screenshots in the manual are nested into a 'figure' environment, but the only purpose of this is to be able to have a caption. The floating feature of 'figure' by using the placement attribute 'H' (='Here!').

This patch makes screenshots non-floating while keeping captions below the images. This is done via the LaTeX package 'caption2'.

Placement attribute for figures is set back to the LaTeX default so that figures can really float should we need it.

Using the latest revision (r20001 - but its been broken since I started using Rockbox) the iAudio M3 does not recharge the battery using either the USB or the Power adapter.

The only way I can get the iAudio M3 to charge is to use Cowon’s firmware.

Added seeking by holdplus/holdminus buttons, pause/play by holdmenu button, hiding the OSD panel by briefly pressing power switch.

Sorry for this article. I am a Chiness boy and my english is poor.But i love rockbox.My MP3 Player is onda vx747.I can’t open any .txt files which larger than 1M on the rockbox system.I don’t know how to solve it and i hope some could send me a message if he could solve the problem.My E-mail:724279694@qq.com.Thanks!

Currently with r24775-100219 on a Gigabeat 20
Checked that it isn’t something to do with the HDD
sometimes after USB transfer or just right after startup, after pressing “Resume playback” it just halts there,showing the album art and sometimes you can change songs/volume but it isn’t playing,then it just freezes and you cannot control anything that needs to be turned off via power switch, and sometimes it requires certain trials before it can normally startup and play.
Additionally, if that happens during startup, it is noticeable that a normal startup produces sort of a background noise,while a buggy startup is simply silent in my headphone.

When loading a saved Brickmania game, the game is loaded corrupted. Please see screenshot attached to see for yourself. There is one brick in the right side which is shown corrupted, and one corrupted rectangle in the left side of the screen which drops like a power object, and stays at the bottom of the screen.

This issue happens on Cowon D2 target. It doesn't happen on the D2's simulator.

Looking at the code and comparing the loading/saving function against the Bubble's game functions, I can see that the return value of file operations is not checked (I'll fix that).
In Bubbles, there's a single file operation of reading/writing the game context struct. In Brickmania there are several consequent file operation to read/write each variable. Maybe the drivers doesn't handle this well on this target. A workaround for that could possibly be to join all saved variables under one game context struct as in Bubbles, but that could mask a real bug somewhere else.

charging isn’t monitored on ipod 3G. it just goes up to 100% very quickly and stays there.

Building Rockbox fails if assert() (in firmware/include/assert.h) is used.

Then, I reworked assert.h.

changes:
When assert() failed, the correction that displayed the file name, the number of lines, and the condition of failing was done.
Moreover, when the log was enabled, the log was output to the file.

Please select the following to make assert() enabled when you make Rockbox.

1) Run tools/configure

2) Build (N)ormal, (A)dvanced, (S)imulator, (B)ootloader, …

    Select "A"

3) (D)EBUG, (L)ogf, (A)ssert, (S)imulator, (P)rofile, (V)oice

   Select "A"

4) make

rockbox 3.5: ipod doesn’t recognize the connection of usb. i understand that rockbox doesn’t support usb on a 3G ipod, but it would be nice to boot into disk-mode like it does for firewire.

This is a first attempt at creating an entry for the new fft plugin. The button table was automatically generated with the attached python script.

The script takes a file (or - for stdin), looks for an #ifdef CONFIG_KEYPAD….#endif block and if it finds one (and it is relatively simple), it parses it and creates the corresponding LaTeX table.

The script is extremely simple but it does provide a good basis for further work.

during my research on FS#10883 i found out that it would be better do disable slide actions on ipods for yes no decisons. slides are too easy done and often cause an unwanted abort.

this patch solves this issue by only accepting pressed keys for abort actions. the solution for FS#10883 has been appended on the bug report seperately.

This patch should apply to all ipods, but needs testing - on both a mixture of ipods and mixture of operating systems. I’ve tested it successfully on my Color with both Linux and Mac OS X.

Current SVN behaviour is to write some magic to the end of IRAM and reboot the ipod when a USB connection is detected. This causes the Apple bootloader to start the disk mode application which is stored in flash ROM.

This patch cuts out the reboot stage and uses rolo to start the disk mode application directly from flash - meaning the ipod enters disk mode almost immediately. This is done in a new rolo_load_rom() function which copies the image from ROM to RAM and then executes it.

This patch tries to avoid the \opt / \nopt hell in manual's tex files, by concentrating all different action definitions together in the platforms keymap file.

Current patch contains changes only to the jpegviewer plugin, in order to demonstrate functionality. Please provide feedback before I spend a lot of time converting all other locations in the manual to this proposed form.

I think this way of organizing keymap assignments is better because it is neater, and each platform has its button assignment all in one place. Adding new platform is much easier this way.

The patch also use one keymap file to all ipod brands, because they are similar to each other (the ipod4g adds some keymappings, but it doesn't matter if they are defined in other ipod brands).

I like to keep the equalizer on with the precut set to -24db, as a volume limiter. I also like the fade on stop/pause set on. When I pause there is a noticeable ‘click’ sound after the music fades out. Also a click before fading in when I resume.

This was not always the case, but I am not sure how old the version I was using, that did not do this.

By the way, this also occurs on the Gigabeat S, as well as Gigabeat F. I don’t know about other models.

Let me know if you need more information.

This patch adds to the simulator the ability to simulate usb on a Linux host.
To do this, you'll need to download, build and install a device driver. You can download it here:
http://sourceforge.net/projects/usb-vhci/files/ Just download the "linux kernel module". See install instruction in it but it's make && make install. Of course you'll need root rights. There also a wiki about it (http://sourceforge.net/apps/mediawiki/usb-vhci/index.php?title=Main_Page)

Now to have usb simulation works correctly you'll of course need to load the driver
modprobe vhci-hcd
And you'll probably need to edit the access rights of the device control device:
violent example: chmod 0666 /dev/vhci-ctrl
other example: chown root:<myself> /dev/vhci-ctrl
Or you can add a udev rule if you can make this work.

You can then run the simulator normally (note the the detection is at runtime so you don't need to have it work before launching the simulator).
Press 'u' to simulate usb insertion and 'u' once more the simulate usb removal.

Some miscellaneous remarks:
-the patch enables usb hid but for some reasons it doesn't work in main menu. However, the remote_control plugins works
-the patch enables usbserial which of no interest here but a way to test bulk transfers
-the patch DOESN'T enable usbstorage because storage simulation is a stub currently.

If it doesn't work, you can still uncomment this line in usb-drc.c:
/*#define USB_VHCI_DRIVER_DEBUG*/
And this line in usb-core.c:
/*#define LOGF_ENABLE*/
But beware ! Your console will end up full of obscure messages.

I'm particulary interested in compile feedback under Windows and OSX.
And of course I'm interested in working feedback ranging from device detection to working state (HID and usbserial) for example.

The Rockbox firmware and cross compilers build by using MinGW.

It is necessary to use MSYS’s make (MinGW’s make (mingw32-make) does not used.).

The cross_compilers.zip is a patch file necessary to make cross compilers using by rockboxdev.sh.

I confirmed the Rockbox firmware, codecs and plugins was built by using the compiler on MinGW.
But I can not confirm whether the Rockbox executes excluding iPod video.

Could you confirm operation to various players?

ROLO currently fails on these targets unless a Rockbox image is being loaded that is sufficiently similar to the one already in memory.

The sequence goes like this:

- rolo_load() loads the new image to
rolo_restart() copies the new image to the start of DRAM (to achieve this without crashing, this function is in
rolo_restart() tries to call invalidate_idcache(), but since invalidate_idcache() is in DRAM this fails as the function has been overwritten.

There are several solutions to this:

1) Move invalidate_idcache() into .icode (easy but won’t fix all targets, esp. those that don’t use IRAM)

2) Create a new .safecode section at the end of DRAM, and move these functions into it (lots of work to update every app.lds and crt0.S, and test every target)

3) Introduce target-specific rolo_restart() functions, as per imx31/rolo_restart.S (less work, as only one should be required per architecture, eg ARMv4/5 etc.)

I’m not sure which of those options is “best”. 1) is certainly the easiest, but 2) and 3) should also allow ROLO to work on targets that don’t use IRAM.

This patch provides a replacement for buffering.c, where there is only minimal buffering (one 32K buffer for audio data and some static buffers for metadata). It is a proof of concept for how this could work on targets with very little RAM.

I would be interested in feedback on the kind of impact this has on runtime, so if you have a flash target please consider giving it a try and reporting your results :)

Note that you will need to disable album art in your build for this to work. I don't even know what would happen if you don't, but it'd probably be bad. To disable it you need to comment or remove the #define HAVE_ALBUMART line in your target's configuration file (firmware/export/config-[TARGET].h).

This patch enables changing the fractal's colors.

Currently, not all targets have proper keymaps defined. This is a work in progress.

I would appreciate any comments.

There should be another option on the list of prioritized options for where to place Album Art images and the filenames. There are currently 7:
http://www.rockbox.org/wiki/AlbumArt

My suggested addition would become the new option 2, pushing all others down.
The first option is currently the only option to allow for song-specific artwork to be displayed, but this requires naming the image files *exactly* like the corresponding sound file, which screws up directory sorting.

Therefore the option should be added that if no image file has an identical name to the sound file playing, it then looks for an image file which matches the current song's Title metadata, similarly to how the following option looks for a match to the Album metadata.

This could cause conflicts when two songs have the same name, or when a song shares the album's name, or the song name contains unusable characters, but such conflicts are rare and minimal, and if anyone cares all that much about such things there is already the built-in flexibility to get around such issues. The additional code required should be minimal (and already blueprinted within the other options), and have essentially zero impact on any other functionality.

I may try to write this patch myself (as i did with "shuffle + track skip"), but if anyone beats me to it, it would be appreciated :)

In  FS#8894  (the original timestrech task), an updated version of the algorithm was uploaded.

The author said it performs and sounds better, so we should try to incorporate it.

I've tried building it, but I can't get a useful result, but I'm also not sure if I used it correctly. I used ./scale 2 < in.wav > out.wav. The result wasn't streched, but had crackling noises every few seconds.

if bookmark=ask is set and the mpeg is stopped, the user is asked for pressing select (for make bookark) or any key (for discard)
on apple devices: if the clickwheel is used for discarding, the bookmark is not set (as intended) but the clickwheel is not working anymore.
to get the clickwheel working again, the keyboard lock has to be set and unset and select has to be pressed.

After reading the irc log shortly after the flashlight plugin was committed i noticed that some want the ability back to finetune the colour of the display. This time i’ve added a fixed point version of the hsv_to_lcd version (thanks to amiconn) and added some more predefined colours. You can “skip” forwards or backwards to the nearest predefined colour (however, it’s probably not the nicest way of doing it i guess).

I’ve also implemented another request to switch the backlight on and off (even for non colour targets) and it now uses the remote backlight too.

Controls:
Targets with a 4 button cross:
Up/Down: fine tune
Left/Right: jump to next predefined colours (including white)
Select: switch backlight on and off

Targets with scroll wheel:
Scroll left/right: fine tune
Left/right or fwd/rew: jump to next predefined colours (including white)
Select: switch backlight on and off

I’ve tried to guess the most intuitive button layout on all targets and even use the remote buttons. However i only own a small number of targets so if you think it can be done better let me know.

Tested on iPod Video, Mini (sim), H300 (sim) and m:robe 100.

I have started an discussion about the virtual keyboard in the mailing list.

In my opinion the text_editor’s control should be similar to the calculator:
- use the whole screen (no tiny font)
- support for touchscreen (raster map)
- separate characters into categories

I adjust the calculator plugin to show my concept.

Hi,
There is a problem in the Chinese voicing. It says "number, bai fen ji" (number %), but it's supposed to say "bai fen ji number) (% #). I don't know if it happens in text because I'm blind. Could this be fixed?

I’d like to suggest the following new WPS feature(s):

1. A viewport can be assigned an image as a “backdrop”.

 a. A viewport may be assigned an image dynamically via the WPS tag "%VX<identifier>"
   (i.e. %VXa for image a, %VXZ for image Z, etc.)
  b. As a viewport is being processed and drawn, its backdrop would be drawn "first", followed by any other normal images/characters.

2. Viewport may define FF00FF as a background color, which would then be “transparent”. This would allow overlapping viewports.

3. Fonts drawn in a viewport with a backdrop would automatically be drawn with DRMODE_FG.

Notes on the attached patch file:
+ It was created from the SVN revision 18997 on Nov 3, 2008.
+ Although I stubbed in the new functions for all the LCD drivers, I’ve only flushed out the 16 bit driver so far.

Cheers!

(sansa fuze)
for some games (such as pokemon)
when you walk around alot;
it is difficult because even the slightest movement of the wheel activates the pause screen;
I have tried multiple controls setups;
and whatever is setup to use the scrollwhell is always extremely sensitive;
a sensitivity setting should be added, to allow a change in the threshold required to count as a button press

This bug currently exists as of rev 21444.

If settings are modified on the recording screen they aren't persistent after a reboot unless another setting is changed somewhere in the menu system.

The problem is that global_settings is being modified without a subsequent call to settings_save().

Attached is a fix for this problem. I've so far only tested it on the h1x0 simulator but I think it's a pretty benign change, unlikely to cause problems on other targets.

For 15-Adobe-Helvetica.bdf:

STARTCHAR ETHIOPIC SYLLABLE NO
ENCODING 4758
SWIDTH 1520 0
DWIDTH 19 0

The above value of SWIDTH, DWIDTH is too larger than that of other Ethiopian characters (This character protrudes from bounding box).

I send this bug’s patch.

Duplicate table and some text found in manual/main_menu/main.tex in section Recent Bookmarks, and in manual/configure_rockbox/bookbarking.tex in section Bookmarking.

These duplicate code sections should be joined, and the two files should share it.

Note: This is work in progress.
Status: Code implemented

      Manual not updated
      Wiki not updated (only after commit)

The idea of this patch is to have the same keyboard keys assign to the same actions in all platforms.

For example, have +/- keys (both on keyboard and on Numpad) are assigned to Volume Up and Volume Down keys of the original platform.
For platforms which do not have these keys, pressing the +/- keys in the simulator will do nothing.

This change will help developers to do manual regression testing on lots of platforms easily, as they do not have to memorize each platform’s key assignment.

Future development: Display key assignment on screen, and/or on console

As discussed on the mailing list this patch gets rid of the “About to Erase Dynamic Playlist” warning and replaces it with a menu option to save the current playlist under it’s existing name.

The attached patch is a first cut for review as I’m just getting used to the menu system. If people think it’s the right way to go I’ll clean it up properly. Any suggestions for tweaks to the functionality also welcome.

Rockbox hangs if the disk gets full during database creation.

Build is r23841 and earlier.

Occasionally when I reboot to the iPod firmware, something has caused the previously unset alarm setting to be enabled and the playback mode is set to shuffle. This doesn't happen with every reboot, but does more than 50% of the time.

Steps to duplicate:

1. Disable the alarm and set the shuffle mode to "None" in the iPod firmware.
2. Reset and boot into Rockbox
3. Listen to a few tracks
4. Reboot into the iPod firmware and check the shuffle mode and alarm settings.

I can't confirm 100% yet as to the time on the alarm being reset as well, but it does seem to consistently read 6 AM - which is a bit of a shock if I've been listening in Rockbox during the day and then I reboot into the Apple firmware and dock in my iHome, expecting to sleep in late on the weekend.

I noticed, that every time I’m in the car listening to music, and I disconnect the iPod 30G (5th gen), while its playing, and I then try to shut it down, it’ll jump to the main window and will not move away from it.

From this point on, I cannot turn off the device nor more away from the main window. Only a HR will resolve this and let the iPod come back to normal working order.

Further more, while it is in that situation (which it is right now, while I write this), the device won’t even go on sleep or turn off the monitor. So basically, it’ll stay with the screen wide awake and lit up.

The two only buttons that will work are the Hold button, which will in turn, turn off the screen and the scroll will allow me to scroll up and down and around on the main window.

Q: What sort of car connection do you use? Line-out+power, or MSC? Or the accessory
I’m not familiar with these connection and their types. All I know is that it is connected to the car stereo from back (ie. the stereo was pull out and the adapter was connected in the back). Also, that it is a connection that connects to the bottom of the iPod (ie. flat and wide connection). It gives me control from the car’s stereo and the steering wheel. When I bought it and then they hooked it up, they told me this is an iPod adapter.

This DOES NOT happen if first stop the music and go to another menu BEFORE I disconnect it from the adapter.

This patch makes the graphic EQ usable in the absolute mode on touchscreen models.
Additionally I made the following changes:

* Add a menu in the touchscreen settings to select the touchscreen mode in the graphic EQ ( because in menus I prefer the grid mode, in the EQ the absolute mode is much better)

* Always try to use the UI_FONT , make the EQ filling the whole screen and add a little margin on the left and right side. In that way it can even used with fingers on a touchscreen (automatic adaption to fill the whole screen should work for all targets with EQ and LCD).

I tested on my Cowon D2 and Iriver H340 to make sure non touchscreen models stil work, both worked perfect.

This is a very early patch to enable USB on the mini2440.

This patch let rockbox react on USB, but unfortunatly i dont get further then the first reset interrupt from USB. Something in the init has to be wrong, so i dont get ep0 interrupt which should follow the reset.

Because of this problems, no attempt has been made to implement the acutal data transfer functions.

If someone wants to step in and debug.. feel free !

These two scripts will, if you run them appropriately generate a few screenshots in an automatic fashion. Execute it like this, from inside a simulator: ./genscreenshots e200.xte /path/to/output

There are a few pitfalls:
* The simulator window MUST gain focus when it is run. If this doesn’t happen, everything breaks. Horribly.
* The method is rather timing sensitive. I had to put a pause of 250ms between each keypress to make sure they registred (too fast, and the sim/SDL would discard them). 250ms may not be the right amount for your computer.
* Rockbox itself is also timing sensitive. If you “push” a button at the wrong time, it may not register, so use plenty of sleeps to make sure things are settled.

Edit: Oops, the first version had a hardcoded filename. Hopefully of such things.

I installed release 3.3 on my Sansa e260. 3.2 worked. On 3.3, volume controls work fine in normal playback mode, but when I switch to FM Radio, they are ignored. If I switch back to normal playback mode, I can set the volume level again, just not while listening to the radio.

This patch enables you to compile the Rockbox simulator with LLVM (you still need to alter the Makefile yourself though).

However, it fails at linking stage with 'file not recognized: File truncated' errors.

Using a bootloader from  FS#9955 , a USB connection is not made if Start Screen is set to WPS, and the user boots Rockbox by inserting a USB cable.

This is possibly also true for other values of Start Screen.

Tested on e280, but I expect it’ll likely be the case on other PP targets with USB

This tracker task will be used to house my Summer of Code work. For information about the goals of the project please see http://www.rockbox.org/twiki/bin/view/Main/PluginLocalization . Please read the comments and the descriptions of each patch.

Latest patch:
July 22

When the wake-up alarm starts up the iPod, you wouldn’t want it to boot the OF, but it will do so if hold is on. This patch makes the bootloader check if the alarm is active and start rockbox regardless of the hold state if it is. Also, if the hold switch is on during start up rockbox would normally reset all settings, but this is inactivated if rockbox was started by the alarm.

Applying the patch:
Besides building the firmware, you will need to build and upload the bootloader to your ipod using ipodpatcher.

Limitations:
The bootloader doesn’t check if the alarm started ipod, it only checks if the alarm is active. If you have set the alarm you will have to use the MENU button to start the OF.

I don’t know if this works on any other iPods than the iPod video, but it will probably work on all of them.

This patch adds more touchpad functionality to the game. It is possible to play by selecting the pieces directly instead of using the simulated buttons.
The changes are:
1. Added touchpad_get_mode to the plugin API.
2. Added menu entry for touchpad devices the switch between button mode and direct mode.
3. The user’s default touchpad mode is save during start-up of the plugin and restored after quitting.
4. The direct input mode is set only during the game (not in menu or view).
5. Extended play loop to handle BUTTON_TOUCHPAD event.
6. A piece is selected by clicking twice on it, moving is also done by clicking the target field twice.

The patch has been tested on the COWON D2 and also seems to compile fine for devices w/o touchpad. The patch has been created with

svn diff -x -w apps > touch_chess.diff

in the root directory. It would be nice if someone could test this (also on non-touchpad devices) and give me some feedback (bugs and improvements).

This is a plugin that locks your player with a 4-digit code. The default code is "0000", until you change it.

Added movement left/right through the date/time fields by the holdminus/holdplus buttons.
