I destroyed the MCU(STM32H743ZIT6) and ST-Link V3.But I don't know what happen.When I connect the ST-LinkV3 with the Laptop, then the ST-Link and MCU was broken.So, if you know what happen, please teach for me.
I think so too.This is embarrassing, but I can't speak English well.So, I can't speak well about the detail.Its cause, short circuit between the ST-Link and MCU through the electrical outlet.So, it isn't concern about ST.I'm so sorry.And thank you ...
