* SND-SOC - how to test drivers ? @ 2010-11-22 21:24 Vaclav Peroutka 2010-11-23 0:07 ` Jassi Brar 0 siblings, 1 reply; 9+ messages in thread From: Vaclav Peroutka @ 2010-11-22 21:24 UTC (permalink / raw) To: alsa-devel Hello all, I am trying to develop ALSA driver for audio subsystem for one Android mobile phone. I already have some messages in the kernel log - please see below. It means that I have s3c-i2s connected to MAX9880 (source code was not IMHO tested). And then the output from MAX9880 goes into unknown switching matrix ( for which I even don't have a datasheet - only register list and names of bits in registers - I can guess what purpose they serve to). What I want is to make some testbench driver and an application which can set switching matrix registers through IOCTL. In MAX9880 I want to preset microphone path to output and switch matrix until I hear my voice from microphone in speaker or headphones. Or, is there any better method how to do that ? AFAIK there is no alsamixer application for Android. What do you use for path and gain settings in this case ? And last question so far - where to look to fix this message: "Failed to add route LMICIN->Mic Input" ? All other routes were added so far.

Please make sure you use the same I2S device (indexed) in ASoC machine driver as your board init file adds to the platform. ^ permalink raw reply [flat|nested] 9+ messages in thread

For debugging stuff like this look at the files in debugfs for ASoC and also #define DEBUG at the top of soc-core.c to get a bunch of trace showing what's being registered and waited for. ^ permalink raw reply [flat|nested] 9+ messages in thread

In the device the CPU (s3c6410) has XPCM*0 pins connected to audio card and XPCM*1 pins routed to GSM modem (not sure about that). In the kernel sources I have several s3c_i2s sources. The raw one, then s3c6410_i2s, s3c6410_i2s-v32 and s3c6410_i2s-v40. And they are very different to each other. I am using s3c6410_i2s-v32 as it is used in similar project. Anyway I am not sure which i2s file I should use...
