L412k8u6 cannot enter the main function during debugging.

[孟祝.1]

L412k8u6 cannot enter the main function during debugging. The same program can be debugged normally with stm32l412 nucleus board.Only when the program is downloaded again can there be a small probability of entering the main function.Is this a hardware problem or an error of the MCU itself？

[TDK]

In general, this is a hardware problem or a software configuration problem. It's unlikely to be an MCU issue.
