Pls help

First which core you used ?

in linux

there are some udev rules like such
https://github.com/rogerclarkmelbourne/ ... v2-1.rules
that needs to go into
/etc/udev/rules.d/


for the 'official' core
https://github.com/stm32duino/Arduino_Core_STM32
you could use stm32 cube programmer as an alternative
