You could use direct i2c APIs to write to SERDES/Camera register from the usecase. When you generate the usecase, it will generate usecase_priv.c file and usecase.c file. You could add an function in usecase.c file to write to these i2c clients. For I2C, you could use APIs like Bsp_deviceWrite8,Bsp_deviceWrite16 to write to 8bit and 16bit address/value pair. These APIs does not require i2c handle, it just needs i2c instance id, slave address, register and value.. We just need to make sure that the i2c instance that you want to use is allocated to M4 driver. and initialized in the PDK. For that, can you see and update Board API Bsp_boardGetI2cData and include this i2c instance on M4? Regards, Brijesh", | |
