ChibiOS Free Embedded RTOS

Sure, chThdCreateFromHeap().
However, usually dynamic allocation is not recommended in embedded systems.

Sorry, but that isn't correct by default. It really depends on every use-case and dynamic memory allocation can enable you to do things with a tiny embedded controller where others ...

Ah!

Ok, I thought the working area is reserved each time a thread is installed. A few years ago I ported NutOS to STM32 and there it is like
NutThreadCreate("t1", Thread1, 0, 512);
The threads memory is pulled from system heap ( in this case 512 bytes)

So I have to double the reservation of ...

I modified the code to use a single thread per UART. And I use a blocking read per thread with a timeout of 10ms.
m
This seems to work, as long as there are not too much errors on the UART lines. If so, the whole things crashes pretty fast. I guess there is some work to do for the error handling ...

Hi Giovanni, thank you for your reply!

Is I thought, there are probably mistakes and misunderstandings from me...

I'll try installing the Studio, sure. Thanks for the hint, I just flew over the comments and wasn't sure about the development state of the studio.

However:
While programming I read ...

Hi all,

First of all, I am not new to embedded and not new to STM32 programming. But this is my first Chibios project on an STM32.
I have most of the available STM32 dev kits but with Chibios I could only get the STm32F4-DISCOVERY to start a USB-CDC device successfully. This is no problem so far ...
