How do I enable the KGDB tool to debug the kernel in stm32mp157 platform

[Wjian.1]

Could you give me some advice on how to debug the kernel through KGDB，

Hello @Wjian.1​ ,

You have to enable the KGDB tool in the Kernel Menuconfig. Go to "Kernel Hacking" and then enable "KGDB: kernel debugger"

You can find more informations for using KGDB at this link:
