Part Number:PHYTC-3P-PHYCORE-AM57X
Hello,
We have an Android OS installed on the AM57x.
The board has the mcasp1 enabled for I2S audio device.
We need to connect a second I2S audio device and guess we need to modify the Android device tree to do that.
Please find below an extract of the Android Device Tree with the mcasp1 and mcasp2 information.
What do we need to put in mcasp2 description to enable it? Do we need to do something else?
Thank you.
Best regards,
Jorge
