Hi, every one, I am new in STM32. Recently, i got 2 STM32L4R9I - Disco. the first one work perfectly fine. as i plug the STLink to connect the first one to the Laptop. it works and the connection also appear on Device manager. i can load and debug the first STM32L4R9I.
However, the second one does not work. I cannot even connect to my laptop even though when i plug in the USB, LED on this second one still light up. I tried to download STM Utility and STM flash Demo but still, no connection found. i have the latest version of STLink driver.
I plan to reset the board by connect PH3 to the ground as i read on some forums.
Do you have any idea to fix the issue???
Thank you very much
