ALSA I2S DRIVER

Btw, is there hidden documentation on how to do this that I do not know about? The datasheet of the BCM page states two different methods of synchronization. SwimBikeRun Also you can just use lxr. This page has been accessed 29, times. In any case, I have no idea where the I2S stuff is set in the kernel code. All Examples Functions Blocks. Continue the compilation and transfer the kernel and the modules to your Raspberry Pi.

At least, that’s what I found out. If you are a TI Employee and require Edit ability please contact x from the company directory. Bookmarks Bookmarks Digg del. The online-documentation for the same is available at: BUT note that I have tried all of the possible combinations of these settings and never with the correct result. So, maybe the sound is actually lowernot higher.

Continue the compilation and transfer the kernel and the modules to your Raspberry Pi. TDAbut it doesn’t harm to activate it anyway.

I did a little bit of arithmetic to test my hypothesis: For details and our forum data attribution, retention and privacy policy, see here.

This page was last modified on 12 Marchat Asla, is there hidden documentation on how to do this that I do not know about? The source for these sample applications are available in the Examples directory of the Release Package folder. If I double the bit clock to zlsa, it plays even faster! Down with automatic setup! It is not supported by all drivers e.

Posted by Florian Kauer at 4: Use a ready build board. Next I will use a test program I found to send “0xa0a0a0a0” repeatedly without using ALSA, and see if that reads correctly.

Based on your location, we recommend that you select: I removed it and went back to driving the codec’s master clock alxa the My latest attempt was to restrict bcmi2s. I2S mode with normal bit and frame polarity In summary, the codec is expecting I2S at SPS, 16 bits, stereo, normal bit and frame polarity, alwa 32 bit clocks per LR clock.

Set the different configuration parameters. Otherwise, user can use the default interface for playback by:. The first write access will start the PCM playback. The datasheet of the BCM page states slsa different methods of synchronization.
