STM32MP157C_DK2 board openocd.cfg file empty

[juliaoconnell-eaton]

Hi there,

I'm trying to set-up OpenOCD debugging for the STM32MP157C_DK2 board in Eclipse IDE. Upon investigation the file boards/arm/stm32mp157c_dk2/support/openocd.cfg is empty.

Based on an example from the Nucleo-F492ZI board and the OpenOCD target/stm32mp15x.cfg the config file should look something like this:

source [find board/stm32mp15x_dk2.cfg]

$_CHIPNAME.cpu0 configure -event gdb-attach {
        echo "Debugger attaching: halting execution"
        reset halt
        gdb_breakpoint_override hard
}

$_CHIPNAME.cpu0 configure -event gdb-detach {
        echo "Debugger detaching: resuming execution"
        resume
}

Thanks!

Zephyr implementation on STM32MP1 is for now limited to Cortex-M4 core, using Cortex-A as Linux host.
Instructions for flashing and debug are provided here:
https://github.com/zephyrproject-rtos/zephyr/blob/main/boards/arm/stm32mp157c_dk2/doc/stm32mp157_dk2.rst#debugging

This is why this differs from usual STM32 targets
