Hi

I use STM32CubeIDE but me and eclipse has never been good friends. Especially the build system and project structure is a pain in the .......
I therefore have moved my project to be selfsustained. I now use code::blocks but have some issues having the gdb working

The first ting I do is to setup the stlink gdbserver, then I use arm-none-eabi-gdb to attach to the target remotly (localhost:61234)

But:

1) Some "additional shell commands" are not executed.
  I try to run a script which sets up the stlink server. The same used by STM32CubeIDE
  If I run the script from a terminal it works, but code::blocks shell says it cant find the script
 
  This is the command
  /opt/tools/stlink/tools/bin/ST-LINK_gdbserver.sh

  If passing this into a terminal, it runs, and the server is started listening on port 61234 as specified
  but code::blocks  says "[debug]/opt/tools/stlink/tools/bin/ST-LINK_gdbserver.sh: 2: ./ST-LINK_gdbserver: not found" when starting debugger

  I also have a sleep 1 command which runs

2) Since 1) does not work I have started the gdbserver manually from terminal for now
    then I start the debugger. It is attaching to target, and code runs but I have no access to debugg info.
    file Z045.elf is loading but I cant set or use any breakpoints, including main
   only thing I may do is to pause or continue, and I can see that the target operates as expected (it have a display among other stuff) but I may not accsess the code
   "Cannot find bounds of current function". Issuing gdb command "file Target.elf" loads the symbol
   Have tried some different debug settings for the compiler. like -g3 and -ggdb with no success

The map file shows that the address 0x080390e4 is within a function,
GDB asks if it could be a corrupt stack, I do not believe that to be an issue. This because the same code runs well within CubeIDE
