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...

Hi,Our board is base on STM32MP157C-DK2 and the HW difference are...1. DK2 CN7 USB Type-C is replaced by micro USB and removed STUSB1600.2. DK2 CN6 PWR-IN is replaced by DC jack and CC1 is 0.4v to PA4 and CC2 keep 0v to PA5.And we would like to progr...

Hello, We made a board that based on STM32MP157C-DK2. First of all, show the configuration of our board as below.... (1). The major parts and circuit are same as DK2 such as DDR, PMIC, MicroSD, Ethernet. (2). Some parts are removed such as MCU, WIFI/...

Hi OlivierG, Thanks for your helping, the problem had been solved. The root cause was the OTG_VBUS did not wire properly since we removed STUSB1600. The DFU function is working well now. Many Thanks,FC

Hi OlivierG, The programmer can proceed the flash operation since update DTS to TF-A and U-boot. But the process is stuck on "reconnecting the device ..." Below is STM32CubeProgrammer log:====================================================...

Hi OlivierG,Thank you for your quick reply.It is true that your magical suggestion is correct and has given us great help.The external clock of our board is a crystal, and DK2 is an oscillator. After setting the TF-A DT clock correctly, our board can...

STM32MP157A M4, the result of ADC_1 always is odd value. (the DR LSB is '1' always.)
