STM32MP157C-DK2 on-board st-link issue

[FEvge]

I have this problem on win10 and ArchLinux. On-board st-link can't find Cortex-A and Cortex-M core.

ArchLinux dmesg log:

New USB device found, idVendor=0483, idProduct=3752, bcdDevice= 1.00
New USB device strings: Mfr=1, Product=2, SerialNumber=3
Product: STM32 STLink
Manufacturer: STMicroelectronics
SerialNumber: 066DFF303739465043114138

STM32CubeProgrammer(v2.1.0) can't find st-link. ST-LINK Utility (v4.4.0) find st-link, but not find target (Detection Fail).

I installed STSW-LINK009 driver (win10) and rules on Archlinux. Firmware version on-board st-link: V2.J32.M22

Hi @FEvge​ 

Please refer to STM32CubeProgrammer user guide

https://wiki.st.com/stm32mpu/wiki/STM32CubeProgrammer

And board flashing instruction :

You can't use ST-LINK to flash the board but the USB DFU.

Hope it help
