STM32MP257F-EV1 Debug using stlink and openocd
Hi
I am trying to attach gdb using openocd to debug linux kernel, I am able to attach openocd.
but when I start with gdb scripts https://github.com/STMicroelectronics/wiki-stm32mp-addons/blob/main/gdb-scripts/Path_env.py
Gdb is not able to get symbols, after connecting, ,I have already build kernel with debug symbols and loaded on target
gdb shows this:
ype "apropos word" to search for commands related to "word"...
Reading symbols from //home/nik/ws/boards/5_stm32mp2/STM32MPU-Ecosystem-v6.0/Developer-Package/stm32mp2-openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06/sources/aarch64-ostl-linux/linux-stm32mp-6.6.48-stm32mp-r1-r0/build/vmlinux...
(gdb) target extended-remote :3333

#1 0x000000000e011000 in ?? ()
Backtrace stopped: not enough registers or memory available to unwind further
Can someone please help here or share the detailed steps to use gdb and openocd?
Thanks in advance.
