00:54:58 Quit krabador (Quit: Leaving)
00:59:39BilgusSo update on natanelion's clipzip we were able to restore it
01:00:01Bilgusevery time he tried to dd data off the drive it failed at 1.6MB
01:00:28Bilgusi Had him pull it with conv=sync,noerror and had a look at the data
01:01:20Bilgusturns out the first 16 mb after the header was all 00 so it was actually using the second 16mb portion to run
01:01:59Bilgusand here I thought it was just junk data its actually a recovery mechanism for when the first blocks go bad
01:02:48Bilgusso in order to fix it I first had him dd the bootloader to that second 16 mb by using sync and skip to align to the proper sectors
01:04:13Bilgusand then for good measure I had him dd the header of the bootloader to the first count=$((0x800)) sectors
01:05:25 Quit JdGordon (Ping timeout: 240 seconds)
01:06:33BilgusI figured out the offset for the first part by looking for where the firmware header began on his dump and coppied the beginning of the bootloader to it
01:06:58Bilgusdd of=/dev/sdb if="/media/pi/NEW VOLUME/clipzip4GB_RECOVERY_image32.bin" bs=512 skip=$((0x74FA)) seek=$((0xAA00))
01:07:36Bilgusdo note those offsets probably won't work for anyone they need to be calculated
01:07:52Bilgusand they are in sectors so it needs to be a whole number
01:09:34 Quit ZincAlloy (Quit: Leaving.)
01:09:42Bilguson reboot his device worked but we wiped out some of the drive header with the new firmwares 'second 16Mb partition' and his device crashed before we could fix it
01:10:15Bilguson reboot we were able to format the internal drive (without the first OF portion exposed) to FAT 32 and all was well
01:11:32Bilgusnext time A good idea would be to limit the count to the remainder of the OF region
01:11:48Bilgusbut its also possible to make that larger if so needed
01:14:44 Join JdGordon [0] (~jonno@rockbox/developer/JdGordon)
01:17:28BilgusI'll give an instance of how I calculated 0x74FA from the recovery image
01:18:14Bilgusthe header starts as XX 06 00 00 EA the XX seems different between all of the images
01:19:07Bilgusbut it started at offset 0x750E which in decimal is 29966 bytes

01:25:24Bilgusah sorry for the (if=) image to write back the offsets don't really matter so much it should have been 0x7200 57 * 512 to stay on the proper sectors
01:25:26__builtinhmm, can someone with a recent dev build on hand test sgt-untangle
01:26:49BilgusI ended up doing it that way because I needed to zero out the first portion that was writable on his device
01:26:57__builtinsomething broke, apparently
01:27:14Bilgushow recent __builtin
01:27:20__builtinuh, like HEAD
01:27:49__builtinI have a feeling the latest upstream sync is to blame
01:29:08BilgusNo issue at 10-4
01:29:24Bilguslet me check more recent
01:29:48__builtinI just tested the latest puzzles native build (with my changes), and it's broken there too
01:30:09Bilgustrying 10-17
01:30:25__builtinthe change in question was yesterday
01:30:35__builtinso that likely won't have the issue
01:30:47Bilgusok it doesn't give me a minute

01:32:26__builtinah, I think I figured it out
01:33:05__builtinturns out there was somewhat of an API change upstream that interfered with my modified untangle code
01:36:09Bilgusis it that you can't select a dot to move it?
01:36:30fs-bluebot_Build Server message: New build round started. Revision 3ad9cae, 273 builds, 12 clients.
01:36:37__builtinshould be fixed in this commit
01:36:37Bilgusyep its there
01:38:06__builtinbasically Simon made interpret_move return a pointer to UI_UPDATE rather than an emptry string to indicate a redraw
01:38:28__builtinbut since I had modified Untangle to have button support, it wasn't updated there
01:38:36__builtinand it was going crazy on a drag

19:20:01 Join JdGordon [0] (~jonno@rockbox/developer/JdGordon)
19:20:40Bilgusgood I have some more optimizations I'd like to do but want to see if this is even worthwhile
19:29:37BilgusI'm pretty sure applying and removing powersave won't affect usability but I also slowed the internal storage clock to 15.5MHZ from 31 so after you get some results if they are promising you might want to test the device out with some heavier codecs and other storage intensive tasks like transfering music to from USB or to from SD card
19:31:49johnb3ok. The runtime with the dev build was ~10h, so it ought to take longer than my morning if there is an improvement. I will report back in 24h ;-)
19:32:05pamaurywodz (logs): I'm not 100% sure but I think that atj actually uses elliptic curve crypto, just quite optimized so it's not obvious
19:32:05Bilgusawesome thanks
19:32:48Bilgusjohnb3 what was the runtime with that FS patch?
19:34:10johnb3Again I did all my benchmarks from internal only, no SD inserted.
19:34:17Bilguswow thats a big improvement but there are a lot of gotchas in that code
19:35:09Bilguswell what I've done here affects the internal the same as sd but you would see less with a High Speed sdcard
19:35:44johnb3I bought 5 more Fuzes on *bay Australia. Maybe some are v1, too. More material to test, but it will be roughly 2weeks until they arrive.
19:38:18BilgusIn that FS patch I saw tweaks to the I2c Bus have you tried running at 48khz with that patch?
19:55:08***Saving seen data "./dancer.seen"
20:03:38CH23Bilgus: how are these?
20:03:45BilgusHmm I was just looking in the assembly output for the as3525 sd code It had a delay added in "Small delay for writes prevents data crc failures at lower freqs" but It was never emited the compiler optimized it right out I wonder if that is why 4channel mode was failing on some devices
20:04:59Bilgusthose look nice but they need a border the clip+ blends lol
20:05:10BilgusITS MASSIVE :p
20:05:27CH23that was with intent actually
20:08:32Bilgusmy screen is all black so it would probably look just like that on my screen just a weird floating bar
