The development version I am using is STM32F401RET6, before that I have ported uCOS-II and System View to see the task scheduling, but Sysview needs to use J-Link, so I followed the tutorials given by SEGGER to convert the ST-LINK/V2-1 that comes with the development version to J-LINK. However, there was an accident during the conversion process, resulting in the loss of ST-LINK, and I can’t burn the programme. Please tell me if there is a way to remedy the situation.
