Chibios 2.5.1 and gdb O0

[sam76]

Hello,

I would try my project under chibios but I can't debug with Gdb. It is based on an Olimex STM32H407 board.

I have tried the simple demo "ARMCM4-STM32F407-DISCOVERY" with a -O0 compile option. The Led blink but a simple breakpoint doesn't work (with -O2 and -ggdb, breakpoint works). I can Singint the program, so it is well attached..

I use openocd 0.6.1 and Linaro prebuilt toolchain :

Code: Select all

arm-none-eabi-gcc (GNU Tools for ARM Embedded Processors) 4.7.3 20130312 (release) [ARM/embedded-4_7-branch revision 196615]
GNU gdb (GNU Tools for ARM Embedded Processors) 7.4.1.20130312-cvs

I have the same problem with ChibiOs 2.4.3

What part fail ?

Hi,

Strange, I don't have any problem debugging using -O0. No idea about what your problem could be, most likely it is related to the toolchain.

Are you using OpenOCD or some other GDB server? what is your debug hardware?

I never had any problems with -O0 myself as well. I am using this toolchain which has also become somehow the community standard.

Hi,

My problem is solved, I have fetched the last openocd source from git and everything work.

I am surprised that no-one have this problem !

Most ChibiOS users use the latest build of OpenOCD because it includes the debugging support for ChibiOS/RT.

It's good to know

Version 0.7.0 of openOCD was just released on 5 May. According the NEWS file, it includes the ChibiOS support.

Cool, thanks for the information! I spread it around.

Time for a new ChibiStudio release then: ChibiOS 2.6.0, OpenOCD 0.7.0 and the updated compiler from the guys on launchpad.

Now that would be lovely indeed, I tried to play with making the newest eclipse play fair with autocomplete and stuff, but after many hours lost in it, couldn't make it work reliably, at least half the stuff is unresolved for some reason, ChibiStudio to the rescue
