openocd -rtos "chibios"

[Tuxford]

I downloaded latest ChibiStudio for Linux. My local openocd version 0.12.0.
Config options are next:

Code: Select all

-f interface/stlink.cfg -f target/stm32f1x.cfg -c "$_TARGETNAME configure -rtos chibios"

But there is no success.

Code: Select all

Warn : ChibiOS/RT memory signature claims to be bigger than expected. Assuming compatibility...
Info : Successfully loaded memory map of ChibiOS/RT target running version 7.0.4
Error: ChibiOS registry integrity check failed, double linked list violation
Info : Only showing current execution because of a broken ChibiOS thread registry.
Error: ChibiOS registry integrity check failed, double linked list violation

What I missed?

Hi,

OpenOCD support is not yet updated to the latest ChibiOS versions.

You may try the ChibiOS Debugger View in ChibiStudio, it provides even better functionality.

OpenOCD support is not yet updated to the latest ChibiOS versions.

Is there any chance this happening? I tried changing `ch` to `ch_system` in `src/rtos/chibios.c` but didn't do the trick alone. Here's what I get now:

It looks like `rlist` has moved quite a bit in ChibiOS 7.x due to the introduction of instances, so this might be a bigger change. Looking into it, but not sure I can get to the bottom of this soon.

You may try the ChibiOS Debugger View in ChibiStudio, it provides even better functionality.

Except that it doesn't provide the stack trace which makes debugging really difficult. Or am I missing something?

Thanks, Szabi

Hi,

It is being addressed, starting from RT7 things changed quite a bit because it added multicore support and some data structures changed.

A repository will appear about this on my personal github or the chibios-upstream github organization.
