Using Linux (LMint 20) what can I do to to trouble shoot ttyACM connection.
LMint 20 (based on Ubuntu 20) no ttyACM connection show up after the DK2 board is loaded with the Flash firmware using STM32 Programmer. The board boots as the wiki shows but no ttyACM devices show up to use with minicom.I am stuck.
Hi, I recently buy a STM32MP157F-DK2 kit and I would want to connect some RS232 devices (one or two), can you suggest me some RPI Hats or Arduino add on shields compatibles with the card ? Thanks
I don't want to use a usb to serial adapter because I need the 9th bit available in the UART and this converters are not generally compatible with that

Resolved! NRST connected with NRST_CORE doesn't boot on powerup
We have own MP157 based module and it sometimes hangs after NRST during debug. It doesn't respond to JTAG DAP, further NRST pulses doesn't help but NRST_CORE helps. It seems as errata "Incorrect reset of glitch-free kernel clock switch". We tried sw ...
Are there any pre-build bare metal examples for the STM32MP157A-DK1?
I was hoping to find any examples/pre-built applications which can be run off the SD card to simply turn on an LED or so, for the STM32MP157A dev kit. Can anyone point me to any resources like this?
