15:13:45bertrikAny SD card experts here? Things start to fail when I expect a response to CMD7 (select/deselect card), while the spec says the card should respond with R1
15:15:08TheSevenfail in what way? timeout?
15:15:16bertrikI don't know exactly
15:15:33TheSevenbut "set RCA" worked?
15:16:00TheSeven(I'm not an SD card expert at all, just looked at that CE-ATA driver a bit)
15:16:38bertrikhm, looking at the code, there is no path where send_cmd can fail when there is no response expected, so maybe by expecting a response now, I'm uncovering some other bug
15:18:00bertrikTheSeven, I'm no SD card expert either and the weird thing is that we have a fairly complete driver, but I don't know which SD controller this is (and it's not documented in the driver, grr). So I have very little knowledge to work with.
15:18:56TheSevenshouldn't the set RCA command also expect a response?
15:19:21TheSevenand IIUC set RCA must be issued before select card
15:21:16bertrikAs far as I understand, you don't *set* the RCA, you ask the card to send it to you
15:21:33TheSevenyeah, whatever that is
15:21:54TheSeveni'm just saying that there should be other commands which expect a response before select card is sent
15:21:55bertrikthe response of this command is the RCA
15:22:35bertrikyes, there are such commands
15:22:49TheSevenand reading those responses works?
15:23:13bertrikThe thing I'm trying to fix/cleanup is the lack of waiting for a response and doing some arbitrary delay instead
15:23:50bertrikI think the hardware receives the responses, but usually we don't do anything with it, at least with the R1 as far as I can tell from the driver
15:26:09bertrikSome commands have an R1b response, which is basically the 48 bit R1 response but also with a busy signal that the host needs to wait for, not sure if the driver does that at all
15:27:05bertrikCMD7 is such a command

15:44:54[Saint]Sure, just ask your question though.
15:46:19diredI'm about to install rockbox with the RockboxUtility on a new sansa clip+ for my sister (christmas present). I'm using linux 64bit. in the documentation it says: "make sure you have appropriate permissions to access the player. Ipod and Sansa players require you to have administrator permissions". I'm not able to gksudo the RockboxUtility :( . Am I supposed to execute it as root or is it alrightey as normal user?
15:46:52AlexPI'm not sure for the new sansa
15:47:03AlexPBut you might need root for the bootloader
15:47:16gevaertsI don't think you do
15:47:26AlexPYou can always try as normal user
15:47:27bertrikthe new sansas don't need access to raw partitions, they just need to put files onto the player
15:47:34AlexPcool, so no sudo needed

16:08:09soapOk, the other day I had mentioned that my Nano 1G problems which I had always associated with FS #7510 are still present (glitching audio playback (apparently after second buffer fill, aka after first "hot" buffer fill) (glitches being audio from multiple tracks mixed together))
16:08:51soapIf anyone has any ideas, I have plenty of time today to test.

16:13:44diredthats... an interesting way sandisk made the display
16:14:53***Saving seen data "./dancer.seen"
16:22:49soapso I guess my real question is, how difficult will it be for me to lower the maximum clock speed of my nano from 80Mhz to 75 (let's say) mhz?
16:23:30soaphow interconnected are all the timings and such? I assume I can't just change the clock speed w/o paying attention to a lot of other dependencies?

16:48:35soapand system-target.h needs changed as well.
16:49:16gevaertssoap: that's only cosmetic I think
16:49:21Buschelsoap: when changing clock you'll need to change PLL_CONTROL and DEV_TIMING1 in system-pp502x.c and CPUFREQ_MAX in system-target.h
16:49:49gevaertsi.e. that's what's shown in the debug menu and used by things like test_codec to work out how many MHz you need
16:49:50BuschelDEV_TIMING1 should not be critical though as 0x808 should be still fine for 75 MHz

16:55:53soapahh, ok, I follow that
16:56:41soapI give up, though, how does that number work? How does 0x8a121403 = (20/3 * 24Mhz) / 2 ?
16:56:52Buschel0x8a12_13_03 = 24 MHz * _19_ / 3 / 2 = 76 MHz
16:57:52soapok, I see how 0x13 = 19
16:58:09Buschel0x03 = divider1 = / 3
16:58:35Buschel(0x13)<<8 = multiplier = 19
16:59:20Buschel(0x1)<<20 = divider2 = /2, (0x0)<<20 = /1

20:31:43n1ssaratoga_: afaiu from the system developer's guide ldm always takes 1c and ldrd takes 1 or 2 depending on the adressing mode used
20:32:27n1sso with sufficiently clever scheduling, ldm can load almost for free in some cases
20:33:54n1sresult latencies seem to be the same iiuc
20:34:03saratoga_n1s: if i understand this correctly, if you do 4 registers that you don't need to access for several cycles, ldm will take 1 cycle, while ldrd would take 2 cycles
20:34:28saratoga_since LDM takes 1 cycle as long as you don't try to access the registers before they're ready
20:34:41saratoga_does that sound right?
20:34:51n1syes (unless you use the exotic adressing modes that take 2c fro ldrd)
20:34:57saratoga_ok good
20:35:14saratoga_i guess its not important anyway since I never have enough free registers on arm to take advantage of that :(
20:37:20saratoga_i'm even stacking my arrays in memory so I can have one pointer and then index into it to get different variables, but its still not enough
20:37:53saratoga_and ldrd has a stupid 255 byte max range on loads

22:11:50TheSevenmaybe they trusted some crappy samsung datasheet? :)
22:12:00TheSevenor maybe 0x00 is just too fast for vsync to work properly?
