Hi there,

 

I'm currently working on phytec mira board, see iMX6 Single Board Computer | Embedded Linux ARM Development Board | Android | PHYTEC 

I wish to use the AUD5 port as I2S master, first I would like to see at least i2s clocks when performing a speaker-test, however even if I'm able to see a soundcard using "aplay -l" I don't have anything in AUD5...

I found some hint here and there and I'm using the work of Caleb see : linux-mx6-ssi-test/0002-DTSI-for-wandboard-loopback-test.patch at master · ccrome/linux-mx6-ssi-test · GitHub in order to use AUD5 as a I2S master.

If you had any leads for me that would be amazing, I've been stuck on this for days... I've started reading the documentation about SSI and AUD, but I'm not understanding everything yet, any help would be deeply appreciated.

 

Regards,
