I made a board with the official STM32MP157 and got the following error when measuring the CPU frequency
The kernel I used was 4.19 and the CPU on STM32MP157AAA3 was able to read the CPU at 650M frequency.I failed to read when I only replaced THE CPU with STM32MP157DAA1.STM32MP157AAA3 To read the CPU frequency results are as follows:STM32MP157DAA1 Reads...

STM32MP157A M4, the result of ADC_1 always is odd value. (the DR LSB is '1' always.)
Hi, I'm porting ADC on M4, but some how the converting result is odd value always, seems the DR bit-0 is always '1'. I tested it by VR, range from 0v to 3.3v, the ADC suppose to convert it from 0 to 255, but I don't know why, I just get odd value bac...
