Hi,

I was testing I2S interface on STM32F107 cpu. I had configured the chip to use I2S3_MCK clock as the Master Clock for the codec. I2S is set in master mode. I had set the MCKOE bit in the SPI_I2SPR register. But the clock is not coming. Is there any other settings I need to do..Please advise

#i2s3-mclk #stm32f107

Usual rules. Ensure the clock to the GPIO bank in enabled, if remapping pins that the AFIO clock is enabled. Configure the GPIO pins for the appropriate AF or input modes. Enable clocks for peripherals, initialize peripherals, enable peripherals.
