| 11:44:00 | lorenzo92 | hi all! For my R0 port I decided that I must take another path, exploit SDL only for audio and not for graphics |
| 11:44:09 | lorenzo92 | this why recompiling a kernel is too buggy |
| 11:44:19 | lorenzo92 | samsung didn't provide the right things probably |
| 11:44:35 | lorenzo92 | so I need to use directly a framebuffer (/dev/fb0) |

| 11:58:14 | kugel | lorenzo92: what's wrong with sdl drawing? |
| 11:58:34 | | Quit Llorean (Read error: Connection reset by peer) |
| 11:58:56 | lorenzo92 | nothing...but recompiling a kernel drives me mad; no framebuffer sleep is possible (= device crash); OF crashes after song changes etc |
| 11:59:03 | kugel | JdGordon: is r30846 alright? |
| 11:59:48 | lorenzo92 | no usb is accessible throug script...I really don't know what's the mess, I tried lots of hacks loosing only time |
| 11:59:49 | kugel | lorenzo92: you don't need to recompile the kernel if you don't do sdl drawing? |
| 12:00 |
| 12:00:15 | lorenzo92 | yes..accessing directly to framebuffer. In this way I don't need to recompile it |
| 12:00:36 | | Join Llorean [0] (~DarkkOne@99-68-45-56.lightspeed.hstntx.sbcglobal.net) |
| 12:00:44 | lorenzo92 | and so, as we have no multiple apps running it's the best deal |
| 12:00:59 | kugel | I don't know how the linux framebuffer works, but I assume it's similar to what we call framebuffer |
| 12:01:01 | lorenzo92 | it should be even faster than sdl and maybe less power consuming |
| 12:01:09 | JdGordon | kugel: its not obviously wrong.. need to have more thna a 10s look to say if it is right though.. probably is |
| 12:01:12 | kugel | i.e. just an array of pixels |
| 12:01:14 | lorenzo92 | yes should be. |
| 12:01:17 | lorenzo92 | ah yes it is |
| 12:01:19 | lorenzo92 | hehe |
| 12:01:49 | lorenzo92 | in 2 words: I map a memory region (240*320*3 size) and then here are our beautiful pixels |
| 12:02:04 | kugel | *3? |
| 12:02:20 | lorenzo92 | uhm...3 bytes x pixel? |
| 12:02:37 | kugel | we use 2 byte per pixel |
| 12:02:43 | lorenzo92 | ah ok :) |
| 12:02:45 | kugel | RGB565 format |
| 12:03:11 | kugel | well, we supprt a number of other formats as well, but this is the easiest to work with |
| 12:03:44 | kugel | you only need to port putting that pixel array to the screen, with format conversion possibly |
| 12:04:19 | lorenzo92 | okay...so now I need to see some other ports. Do you suggest me one? |
| 12:04:38 | lorenzo92 | what are the main functions to be "binded"? |
| 12:04:58 | kugel | lcd_init_device(), lcd_update() and lcd_update_rect() |
| 12:05:40 | kugel | (lcd_update()/_rect can wrap each other if wanted) |
| 12:06:26 | *** | Saving seen data "./dancer.seen" |
| 12:07:04 | lorenzo92 | perfect. Seem to be not so difficult, maybe it is a bit for me that I'm still not so C-guru haha |
| 12:08:18 | lorenzo92 | ah another question...lcd-charcell in your sdl port is used to simlulate something? Do I need it? |
| 12:08:26 | kugel | no |
| 12:08:35 | kugel | the simulators use sdl |
| 12:08:53 | lorenzo92 | okay I guessed that. So I need to remove them..thanks |

| 17:37:14 | kugel | from what I gather there's no problem to re-use the alpha blending from AAF for transparent bitmaps |
| 17:40:51 | kugel | the only problem is that they need a different in-ram representation than normal bitmaps (which are converted to native format at loading time) |
| 17:42:35 | kugel | anyone fancy implementing it? :) |

| 18:23:00 | bertrik | but red and blue are still reversed, so it appears as BGR565 encoding instead of RGB565 |
| 18:26:48 | bertrik | apparently there can be two different kinds of display on the clip zip, but unfortunately I can't find a datasheet for the one now in my clip zip |

| 18:57:32 | kugel | thinking about the internal representation. What would be nicer/better? store as 32bbp (as in the bitmap file), ARGB8565 (24bbp) or alpha and colors entirely separately? |
| 18:57:54 | kugel | (e.g. a rgb565 buffer and a alpha buffer (4 or 8 bbp)) |
| 18:58:19 | kugel | I think the latter would be the easiest to implement, since the existing rgb565 can be reused |

| 19:19:23 | pamaury | I sent you the archive |

| 19:20:49 | pamaury | when it's done, you don't need to rebuild, I sent you the fully built version but I encourage you to check it's build correctly with make clean && make |
| 19:21:33 | pamaury | then in utils/imxusbotp/ do: sudo ../imx_hid_recovery/imxhidrecovery 1024 usbotp-hack.sb |

| 19:30:17 | Zoiah | To figure out the parts and stuff, right? |
| 19:30:24 | Zoiah | Or something else in particular? |
| 19:31:27 | pamaury | Basically if you want to port rockbox you will need to figure out: the hardware (did you open it ?), what to keep in the OF (like memory init and so one), how to init the external hardware like LCD, nand/sd/audio codec if any... |

| 19:59:50 | pamaury | no, it begins with ____, then ____ can switch to another section |
| 20:00 |
| 20:00:07 | pamaury | usually it's switching to host if usb is plugged and play otherwise |
| 20:00:25 | pamaury | but here there are more so I can't really tell, you'll have to look at the code to see |
| 20:00:46 | pamaury | In any case, you should begin with ____ and then go to host because these are probably the "simplest" |

| 20:49:24 | Zoiah | Hm, should see which functions refer to the NAND_ thing and if they also exist in the other. :) |
| 20:52:28 | Zoiah | pamaury: maybe it would be beneficial to also dump the bootloader of this device to see if it has been customized in any way? |

| 22:10:40 | pamaury | Zoiah: the elf files shouldn't differ :-/ |
| 22:11:38 | Zoiah | The changes aren't distributed in filesize, strangely enough. |
| 22:11:58 | pamaury | you should read the SbFileFormat page on the wiki or download the source of sbtoelf on freescale website (there is a pdf with the spec); basically the elf files are just a way to reverse engineer it, it's not something really concrete |
| 22:12:00 | Zoiah | http://pastebin.com/Qet9QZHF |
| 22:12:40 | jhMikeS | fml: yeah, it's basically "height = s->vp->line_height ? height : (int)font_get(s->vp->font)->height;" and not standard |
| 22:12:49 | pamaury | the first section to be executed is ____, it "runs" ____.0 then ____.1 etc and then either it stops or one of the "CALL" asks the bootloader to jump to another section |
| 22:13:50 | fml | jhMikeS: I didn't know it's possible (I mean the syntax). Shouldn't it be changed to standard? |

| 22:14:32 | Zoiah | pamaury: amount of differing versions of that file. |
| 22:15:01 | Zoiah | pamaury: so, 10 runs of sbtoelf on the same source ends up with 10 different copies of FIRMWARE.____.2.elf. |
| 22:15:04 | pamaury | can you pastebin the diff between two versions. Check that the output of sbelf says all checksums are right, |
| 22:15:06 | | Nick [Sanyi] is now known as [sanyi] (~sanyi@unaffiliated/alexanderc) |
| 22:15:40 | pamaury | perhaps I broke sbtoelf in one of the recent commits :-/ |
| 22:15:46 | pamaury | let me check |
| 22:16:28 | Zoiah | http://pastebin.com/BGW6RjJr |
| 22:16:36 | Zoiah | I'll re-run my sbtoelfs and record the outputs. |
| 22:17:59 | pamaury | might be some padding I introduce in the elf files, that's really weird |
| 22:18:45 | Zoiah | Maybe my box is broken. ;) |

| 22:20:24 | Zoiah | pamaury: output of sbtoelf is even the same, even though it results in 10 different copies of FIRMWARE.____.2.elf |
| 22:21:01 | | Quit The_Seeker (Client Quit) |
| 22:22:37 | pamaury | ok, if the output is the same, it means crc went all good so the tools either adds some padding I'm not aware of (that would be strange ^^) or this is some uninitialized data (bad !) |
| 22:23:48 | | Quit keyb_gr (Ping timeout: 240 seconds) |
| 22:24:29 | pamaury | Zoiah: I've got the answer |
| 22:24:35 | Zoiah | Woo. :) |
| 22:24:56 | pamaury | I think because of some padding, when fseek-ing, it will write some unitialized data |
| 22:25:29 | pamaury | that is, if I fwrite from 0 to 6 and then fseek to 8, byte 7 will be random |
| 22:25:34 | Zoiah | That makes sense. |
| 22:26:02 | pamaury | that's a bit bad, I'll try to change that, I don't like this behaviour |
| 22:26:24 | pamaury | I knew it, because valgrind report unitialized data when fseeking |
| 22:33:34 | Zoiah | BTW, SA3ARAK08 (succesor of this device) has the same firmware format, but different key. |
| 22:33:44 | Zoiah | But the sectionnames aren't encrypted. |
| 22:33:55 | Zoiah | There they have a mlc_ and mmc_ instead of mlc_ and lba_. |
| 22:34:46 | Zoiah | And an S version of every executable. |

| 22:43:38 | Acorn | oh, just realised the error is thrown by the input handling |
| 22:44:26 | Zoiah | pamaury: oh, and not sure if this is your code, but the abort() thrown by the default getopt-handler is a bit harsh. ;) |
| 22:44:45 | Acorn | hmm, now it just gets stuck on a "loading.." splash :( |
| 22:44:58 | Zoiah | pamaury: and confusing, because the usage outputs a -r for raw mode, but getopt doesn't handle it. |
| 22:45:51 | pamaury | Zoiah: abort should never happen, it means a bug, I must have overlooked the short mode |
