ChibiOS Free Embedded RTOS

Hello Giovanni.

Many thanks for creating the Sub-Project!

I don't have the hardware at hand to really run the project proposal, but will try to get it compiled for a start.

Hello Giovanni.

What do you think of the idea adding a ChibiOS/SB discussion in Sub-Projects?

I have been tinkering a bit with the SB demo code and got it working - kind of.

This task is defintely more advanced than just adopting an RT demo to ones needs, as it includes handling several projects ...

Hi all!

I just updated the ChibiOs extensions via the eclipse update feature.

A quick test with the initial setting of 128 entries in the trace buffer worked flawless.

Great job and great news getting a useful feature up and running, quite a bit faster too!

I'll do some more in depth testing ...

Hello Giovanni.

The trace buffer is sized 128 (default):
#define CH_DBG_TRACE_BUFFER_SIZE 128 in chconf.h

The address its trying to fetch is located in the ch0.trace_buffer.buffer starting at 0x20000a28 (ch0+144).

For example it tires to fetch from 536875240d = 0x200010E8, which is offset by ...

Hello Giovanni!

I dug a bit further into this and made a strange observation:

I enabled #define CH_DBG_TRACE_MASK CH_DBG_TRACE_MASK_READY in chconf.h.

Then i put a breakpoint at the end of void __trace_ready(thread_t *tp, msg_t msg) { in chtrace.c.

I got a valid output in the TraceBuffer view ...

Hello Giovanni,

it is the RT version included in the freshly downloaded: ChibiStudio_Linux_2023-02.7z (881.6MB) as of today.

In there i used:
chibios_stable-21.11.x

chibios_stable-21.11.x/os/rt/include/ch.h says:
#define CH_KERNEL_VERSION "7.0.4"

BTW: I set this in chconf.h too:
#define CH ...

Linux Mint 22.3 - Cinnamon 64-bit

ChibiStudio_Linux_2023_02.7z actual version as of 2026-03-19 freshly downloaded and installed

Demo: RT-STM32F303-DISCOVERY running on a genuine ST board

chconf.h settings: ALL debug switches set TRUE

Everything else unchanged

Hi all,

when i run and debug the ...

Hi all,

compiling hal_xsnor_base.c gives below warning:

Hi all,

wouldn't it be useful to have a hook function upon actual character reception on the sequential stream?

Why? To give a visual feedback by flashing an LED for example.

The associated code must be very short for obvious reasons.

I'm aware, that you can register ...

Hi all,

not wanting to be pedantic but to improve the product:

When giving an argument with the help command (silly thing to do), xshell prints aout Usage: help help .

Line 225 shoule be
xshellUsage(xshp, "");

instead of
xshellUsage(xshp, "help");
