I’m trying to debug a small program running under STM32CubeIDE with FreeRTOS (v2) as middleware. I’m trying to receive and transmit characters from USARTs . As it seems I’m not able to set a breakpoint in an interrupt service call back. I enable the receiver interrupt but when typing a character, the program doesn’t get into the ISR.
If I comment out any FreeRTOS related OS initialization and task setup in the program startup code, I can intercept the interrupt.
Is there something special to know about when FreeRTOS is in the game?
FreeRTOS doesn’t affect your peripheral interrupts. It only cares about its SysTick.
Maybe something goes wrong during task setup and scheduler start and the application crashed or stopped due to an assertion. (Did you define configASSERT ?)
Where is the application when you just halt the target ? What’s the call stack ?
Do you check the return codes of the FreeRTOS related create/init functions ?
BTW when using FreeRTOS (FromISR) API in an ISR ensure to create/initialize everything needed before enabling the corresponding interrupt.
May be an optimization problem. Cortex M optimization is unbelievably powerful but can lead to assembly code that is almost impossible to match with the source. Try unoptimized code or adding some unoptimizable fragment such as
{
volatile unsigned long aDum = 42;
}
Cannot imagine that the invocation of a callback routine within the actual ISR gets optimized away.
Just to be sure: You can set the breakpoint but it doesn’t get hit. I mean you’re trying a (non-optimized) debug build with all symbols etc., right ?
Hi Krischu,
AS hs2 mentioned, FreeRTOS only cares about SysTick. However, STM32 HAL requires another SYS timebase timer for STM’s HAL. Can we also check the SYS timebase source in device configuration tool? SysTick timer is preferred for FreeRTOS. If source is also SysTick, we can choose other unused timer as SYS timebase source.
That is not what I meant, sorry. The issue is that debuggers may have serious trouble matching high level source code with assembly code. I have seen that a perceived million times: You can set a bp no problem, but the debugger never breaks there. Alternatively to using the dummy statement I mentioned, try compiling a hard break into your code:
__asm {“bkpt”};
your syntax may very.
Hartmut tried to raise the same point I believe.
This is the output of a just launched build all:

And I can say that now the interrupt is caught. And it works reproducably. Strange. Maybe the incremental build leads to strange effects?
Well, an inconsistent build might fool the debugger and can cause strange effects as @RAc mentioned. You SEEM to set a breakpoint at a certain source line but in fact it’s not exactly there and is not hit as expected. A leaky build system is a nightmare and I’ve often seen people always do full rebuilds because they didn’t or couldn’t trust the build system.
I’m still at the problem. Not solved. Could it be, that a task is running at higher priority than the interrupt (although I’m aware that IR priorities are sth. different than task priorities). But I can’t get the heck stopping in the receive ISR when RTOS is involved.
__asm("bkpt"); // BTW
The above “hard wired” BKPT seems to work. But Using CubeIDE to set a breakpoint it never gets caught.
EDIT: meanwhile I found that things get better (bkpt caught in ISR) when I do the
LL_USART_EnableIT_RXNE(USART1); at the beginning (before the for(;;) ) of StartTask1.
Does this mean that interrupt was not enabled earlier? One thing you can check is turn off compiler optimizations as suggested before.
Also, this seems more like STMCudeIDE question and therefore, I’d recommend asking on ST forums.
In the first place I did the LL_USART_EnableIT_RXNE(USART1); before the osKernelInitialize().
Again, try adding unopimizable code (see the “volatile dummy” statement I sketched early in the thread as an example). The Cortex M is notorious for optimizations that make matching of source and assembly code a nightmare for debugger developers.
In the end I managed to get my UART i/o , ringbuffer and IR controlled, running. I would say, that the asm(bkpt) was at least the best remedy to verify the funcionality. At the moment, the application is running fine and I can even set a soft breakpoint in an interrupt routine. Thanks for helping.
