1.Excuse me, do you mean that I2S is set to two places?
How to modify the settings in the official IMG?
2.For the COLCK part, if I set ROCK PI E as MASTER, then LRCK and BCLK should be sent by ROCK PI E. Do I need to do any additional connections? For example, do I need to provide the frequency of MCLK externally?
