Which cores are the STLINK-V3EC can support, does support cortex A35/A7 core？

[Da_Vinci]

Recently，I test STM32MP2 with STM32MP257F-EV1 board.
I want to debug A35 core with STLINKV3 that on the STM32MP257F-EV1 board，does it support ?
And which cores are the STLINK-V3EC can support,except cortex M.

Hi,

you should being able to debug any cores with either embedded STLINK-V3 of the STM32MP257F-EV1, or using external STLINK-V3SET or 3rd party debug probes (e.g. Lauterbach Trace32, ULINK, etc...).

Hi,Patrick,

I know that STLINKV3EC on the STM32MP257F-EV1 board can debug the M33 core, now I want to debug the cortex A35 core by it, but when I choose the A35 core in CubeIDE, it reminds me that this probe does not support.

the second question,  after choose the M33 core in CubeIDE debug configuration window, the STLINKV3 could be find in this window, and get the SN of STLINKV3, but when back to main window, after click debug button, the IDE pop-up a window say that can not detect the STLINK.

Using the 3rd party debug probes, the M33 and A35 core all can be debugged normally by SWD.
