arm-none-eabi-gcc : unable to see local variables in modeldebugger

CDAMP

Hi,

When I load a simple C target binary built with arm-non-eabi tool chain loaded on the ARmCortex-M7 Fast Model in the fast Models framework it fails to show the local variables complaining "??? (can't read from memory from 0xFFFFFFFFFFFFFFF4 (size =4).

My compile command is utterly simple:

arm-none-eabi-gcc -march=armv6-m -mthumb -g3   -c -o <source>.o <source>.c

Anyone has an idea what's wrong ?

Regards,

CD

    I found a resolution to this - finally.

    The model debugger successfully shows the local variables when target is built with DWARF2 debugging format, so building the target code with -gwarf-2 option fixed the issue. The default format of debugging info, I believe stabs does not work
