I updated a project from FW_F4_V1.7.0 --> FW_F4_V1.8.0.
After the Update the I2S Interface did not work any more.
I use an external clock on I2S.
I found a difference in file stm32f4xx_hal_i2c_ex.c in line 1400.
in file from FW_F4_V1.8.0. the line
is missing ?
I could not see any difference in void SystemClock_Config(void) from 1.7.0 to 1.8.0, so
I added this line to stm32f4xx_hal_i2c_ex.c and I2S worked again.
is this a bug?
