Does STM32MP157D-DK1 onboard STLink support linux kernel code debug？

[mingming]

I’m new for STM products. After some google, I found mp157d-dk1, I want use it to study Linux kernel. Does the onboard STLink support Linux kernel code debug? Like set breakpoints/single step/observe variables values?

Another question, is this boards newest model? Is there better/newer one?

Hi @mingming

Regarding boards, the STM32MP157D-DK1 is the latest board for STM32MP15. The STM32MP135x-DK is newer, uses same Cortex-A7 (single-core only) and run same Ecosystem (i.e. same Linux kernel).
