I was going through the driver files for CS47L63 and apparently I2C is not supported for some reason. Here is the code block I'm talking about
static uint32_t cs47l63_comm_i2c_reset(uint32_t bsp_dev_id, bool *was_i2c_busy)
{
LOG_ERR("Tried to reset I2C, not supported");
return BSP_STATUS_FAIL;
}
static uint32_t cs47l63_comm_i2c_read_repeated_start(uint32_t bsp_dev_id, uint8_t *write_buffer,
uint32_t write_length, uint8_t *read_buffer,
uint32_t read_length, bsp_callback_t cb,
void *cb_arg)
{
LOG_ERR("Tried to read repeated start I2C, not supported");
return BSP_STATUS_FAIL;
}
static uint32_t cs47l63_comm_i2c_write(uint32_t bsp_dev_id, uint8_t *write_buffer,
uint32_t write_length, bsp_callback_t cb, void *cb_arg)
{
LOG_ERR("Tried writing to I2C, not supported");
return BSP_STATUS_FAIL;
}
static uint32_t cs47l63_comm_i2c_db_write(uint32_t bsp_dev_id, uint8_t *write_buffer_0,
uint32_t write_length_0, uint8_t *write_buffer_1,
uint32_t write_length_1, bsp_callback_t cb, void *cb_arg)
{
LOG_ERR("Tried to write double buffered I2C, not supported");
return BSP_STATUS_FAIL;
}
Is there any explicit reason as to why these functions are disabled and not supported?
If I wanted to use I2C along with SPI for transfer between the codec and SoC, is that possible?
