Hi

I would like to know if  it can use I2C in SOM mode?

I saw the init_sensormode_functions[] which includes i2cm_init()  in platform_oem_som.c 

I invoked   qapi_I2CM_Open to initialize  QAPI_I2CM_INSTANCE_002_E  in  som_app_init()

but It will return  QAPI_I2CM_ERR_PLATFORM_INIT_FAIL.

Have I missed something??

Thanks

SOM mode supports I2C functionality, however the  functionality is limited to Sensor reading and sensor processing.

Kindly refer to section 3: QCA402x framework and programming model from document 80-YA121-142 QCA402x (CDB2x) Programmer's Guide.
