hi
I have some of nucleo boards(F446ZE, F303RE and stlinkv2) for the test before make the board.
A weeks ago, I uploaded skecth files by arduino IDE with st-link v2.
(I saw st-link v2 doesn't have VCP, but it works with COM port when i just plug st-link v2. i think because I tried the debugger BMP(couldnt use full name...) before. )
It worked nicely, but It doesn't work now.
so I have tried several methods and confirmed that the connection is possible using stlink v2-1 of another nucleo board.(connect 3 wire: GND, SWDIO, SWCLK)
stlink v2-1 can connect with arduino IDE(COM) and STM32 ST-LINK Utility. but STLINK V2 doesn't work even when i connect by ST-LINK Utility and TrueStudio.
I dont know why, just do I need to throw away ST-LINK V2?
and I have worried about the board that i will make will not connect with debugger.
