12:06:56_bilgus_OH speaking of that line out stuff as I'm going through adding the extra defines for LO detection
12:07:40_bilgus_the thought occurs to me that maybe its current behavior is better if you want to plug a hp && lineout at the same time

12:08:58speachyit supports it but I can't really think of a situation where you'd want to do that.
12:09:21speachysince you can't control the volume indepdently, and LO needs the volume maxed out.
12:09:57_bilgus_ah so so LO affects HP as well?
12:11:22speachythe cs4358 (?) only has one audio output, and it's connected to two different output amps.
12:14:49speachywe only want to max the volume (ie bypass the user selection) if the HP is *not* plugged. The output amps are enabled by their respective plug detect switches.

12:17:08_bilgus_ok then I shall continue

15:02:31_bilgus_okg#2749 is up I havent had any spurious detections with either port so far after enabling the pullup on lo.
15:03:25_bilgus_I had to switch the headphone caused pause boolean in order to get the lo to stay playing on startup
15:04:10_bilgus_It does seem to glitch the wps now on plug/unplug but it very well may have done that before

15:11:00speachyno, I don't mean the lockout −− I mean if you have that pause-on-unplug, with both plugged in, and you unplug one, it'lll pause.
15:11:27speachyeven though the other is still plugged in.
15:12:22_bilgus_yes it'd still pause
15:12:32_bilgus_thats what I was referring to earlier
15:12:43*speachy nods.
15:12:51_bilgus_uh the enable speaker one is not right I have that logic backwards
15:13:24_bilgus_doesn't affect this target but I figured i'd add the functionality there too
15:13:25speachythat's probably okay. I consider simultaneous hp/lo usage to be user error..
15:22:02_bilgus_eh I'll have to think about the speaker one for a bit gtg

19:51:58braewoodsoh, i see.
19:52:06braewoodsi thought there was some reason.
19:52:37braewoodsthere's Linux support for MTP and such so I thought it would be a nice option.
19:52:45braewoodsi thought maybe there were technical reasons why.
19:53:41braewoodsat some point I'll see if there's an viable MTP implementations that can be ported.

20:00:16braewoodsHm. Seems there's a Linux port.
20:00:37braewoodsMaybe I can tie that into the rockbox USB stack.
20:02:15speachyTBH you're better off starting with that mtp-new branch and forward-porting it to current master.
20:02:53speachythe actual mtp-specific stuff is self-contained but there's a lot of support code around it.
20:03:03braewoodsI see.
20:03:28speachyanother possibility is to start with one of the hosted targets and use a native linux OTG MTP implementation.
20:03:55braewoodsI'll figure something out. I want to research options first.
20:04:07braewoodsI do know I don't want to write the MTP code from scratch.
20:04:48braewoodsi expect most of the MTP clients are going to be using libusb with some MTP library.
20:04:56braewoodsbut we want an MTP server of sorts.

20:57:51speachy_bilgus_: still getting occasional ROLO hangs.

21:00:37speachyoh, just noticed the date/time in the debug menu is ... quite janky

21:02:00_bilgus_someone isn't adding 1900 apparently
21:03:08_bilgus_well ingenic told me to FO
21:03:34_bilgus_Sorry .We don't support JZ4760B anymore.Thank you.
21:03:35_bilgus_Best Regards, support
21:03:51speachywhat were you asking for? (anything?)
21:04:05_bilgus_maybe someone who visits the forum will have access to wechat
21:04:40_bilgus_that second manual the one that has the DMA SADC and few other things I'd really like to read about
21:05:02speachyoh, that "UI" manual
21:05:33speachytheir SDK sources might have useful bits in there.
21:05:55_bilgus_oh and the CODEC part!
21:06:17_bilgus_I managed to get all their sources from their ftp took like 2 days
21:06:57speachyI have a complete mirror of that too
21:07:18_bilgus_yeah it's clearly not gonna be there forever
21:10:17speachyoh, I managed to find a copy of the upstream MUSBHDRC documentatio
21:12:42speachynot sure if it matches the core revision that the jz4760 uses but it's much more useful than the ingenic docs.

21:23:49_bilgus_I'm not overly impressed by anything dealing with ingenic tbh
21:25:20_bilgus_hehe I asked in #mips-lab and they guy told me to use google and linked me to our own document lol
21:25:42_bilgus_s/ they / a
21:25:56speachyheh
21:27:15_bilgus_the heaphone / lo stuff should be good now I left the FS open to hear back from the OP but its set to close in a week
21:27:51_bilgus_if you plug both it pauses if headphone is plugged it takes priority
21:28:08_bilgus_unplug l/o while hp is playing no change
21:28:51_bilgus_plug both unplug hp goes to lo
21:35:56_bilgus_So at this point I assume you are confident that it is possible to make RX work given enough time?
21:36:54_bilgus_I guess I should try a disk speed test on the OF that might tell

21:41:08speachydefinitely. I've restructured the RX flow, and now I've finished about 2/3rds of the DMA plumbing for it
21:46:09_bilgus_judging by the seq write speed they are not using dma
21:53:02speachyI agree

21:59:26speachycode complete.
22:00
22:01:09_bilgus_damn
22:01:32speachyokay, didn't break things with RX DMA compiled out
22:01:36_bilgus_hmm the sequential read says they are using dma
22:02:22speachydevice RX is the complex case
22:02:59_bilgus_SW: 2.65 RndRW 0.69/0.45 SR: 10.06 mbps
22:03:38speachyDMA compiled in, but disabled, still works..

22:05:24speachyand small-transfer RX DMA is ... busted.

22:15:52speachyDMA went thrrough ok but for some reaon the logic thought there was another 900-odd-bytes remaining...?

22:37:31_bilgus_ errant bit?
22:38:17speachyconvoluted logic; I'm getting the DMA complete interrupt but not the endpoint complete interrupt.
22:38:32speachyI cleared the DMA state too early so latter code didn't do it properly
22:39:02speachybut that doesn't explain the wonky FIFO; there's no way the FIFO should report having that much crap in it.
22:39:15speachygot past that but now the whole thing is stalling
22:46:27speachyfound an inverted, um, inversion.

22:49:17speachysweet, it's working for short transfers now.
22:50:36_bilgus_nice!
22:52:49speachyaaaand broken for larger transfers. I'm probably going to trash my SD card doing this. :/
22:53:29_bilgus_throw a cheapie in there
22:53:55speachytwo slots, fortunately
22:54:05speachydon't want to corrupt my data
22:58:15speachyok, first block transferred, things go wonky after that. DMA/RX quirks rearing their ugly head, basically.
22:59:30_bilgus_does this dma have a shift mechinism like stride for the display stuff
23:00
23:00:11speachyno
23:06:07speachythis is the auto-rx stuff breaking. or rather, my logic isn't quite right yet. I'm getting a spurious interrupt that makes me think we got a 0 length transfer.
23:06:20speachyprematurely terminating the flow.

23:14:30speachyI think the issue is that we're getting a DMA interrupt _and_ a EP interrupt for the same transfer.
23:15:31speachyand that's breaking the accounting
