ChibiOS Free Embedded RTOS

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:


[stm32f1x.cpu] halted due to debug-request, current mode: Thread
xPSR ...

Actually I have a main.cpp. I tried putting it there making sure it has C-style linkage, but that didn't help, either.

Do you think it has something to do with messing around with the vector table? I partitioned my flash, the first 128kB is for the bootloader, the main app starts after that. So for ...

I'm using the most recent version of GCC included with ChibiStudio:



I tried it with 10-2020-q4-major, but got the same results.

Here's my linker command:

arm-none-eabi-g++ <all object files> -mcpu=cortex-m4 -O0 -ggdb3 -fomit-frame-pointer -falign-functions=16 -Wall -ffunction-sections -fdata-sections -fno-common -nostartfiles -Lboard/ -Wl,-Map=build/firmware&#46;map,--cref,--no-warn-mismatch,--library-path=ChibiOS/os ...

Thanks @Giovanni. I checked the map file, and my symbol appears under "Discarded Input Sections". I guess the linker dumps it before it has a chance to override the weak version. But I was unable to keep it in even by marking it with __attribute__&#40;&#40;used&#41;&#41; .

There are two more ...

Hi,

I want to override the default exception handler. I see it's a weak symbol so all it should take is to create a function with the same name and signature, right? So I created a file called handlers.c with the following content:


#include <stdbool&#46;h>

void _unhandled_exception(void ...

Thanks. That makes sense, but it still doesn't explain why -Og code is smaller than -O0. As far as I understand -Og disables at least all those optimizations as -O0 (and maybe more).

Hi,

I'm using ChibiStudio with included GCC 9.2.1. I noticed that when I compile my code with -O0 I get a binary size of around 70 kB. But when I wanted to add more debugging information with -Og -ggdb, the compiled binary size dropped to 47kB and the debugging experience is like with -O2 or -O3 ...

Korken,

What's the reason for declaring most of the classes final? IMHO it takes out the elegancy from interfacing ChibiOS with C++. For example, with the old wrapper you could derive a class from BaseStaticThread, define a main() member function and call any thread-related function implicitly ...

Thanks Giovanni, but I found my way around this. LWIP provides the LWIP_NETCONN_THREAD_SEM_ALLOC() and LWIP_NETCONN_THREAD_SEM_FREE() macros which are called if the thread semaphore is invalid (as defined by the sys_sem_valid() function in sys_arch.c) or not needed anymore, respectively. This ...
