I have an custom STM32H743 TQFP100 board. I use I2C 4, PB8, PB9 at 100kHz.
The code is generated with CubeIDE.
The I2C_FLAG_AF flag on I2C4 is always wrongly set and the transmission after adress is aborted.
The device sends an acknowledge.
Is this an bug or my error?
On the Nucleo H743ZI2 I don't have these issues.
