Other Parts Discussed in Thread: TLV320AIC3206,
Hi,
I'm using SDK-LINUX-AM57X 06_03_00_106 on our custom board.
It has 3 sound devices. All of them are TLV320AIC3206.
One is selected I2C interface, others are SPI.
I2C works good, as shown my post.
e2e.ti.com/.../am5718-linux-am5718-audio-codectlv320aic3206-by-using-mcasp-i2c
SPIs do not work.
Driver is loaded, but can not set parameters in 'amixer' command.
