Tool/software:
Hi, TI expert!
I have a development environment for am6234, with our own evaluation board.
The software SDK version is PROCESSOR-SDK-LINUX-RT-AM62X-10.01.10.04.
The model of the audio codec chip is TLV320AIC3101IRHBT.
Set the codec chip as follows:

After performing the recording operation below, the recording cannot be performed normally and the error message above appears:
