I’m currently working on a project that involves configuring I2S on a BPI-P2 Pro running Debian. I need the board to function as the I2S master. However, the process seems quite different from what I’m used to on the Raspberry Pi.
Could anyone guide me on which files I need to edit and what additional modules or settings I should load to achieve this setup? Any specific tips for the BPI-P2 Pro would be greatly appreciated!
Thanks in advance for your assistance!
Try to look at [RESOLVED] New kernel update for BPI-P2 Pro - #9 by eComet. I2S is working here. Also I tested it by internal test script.
