ChibiOS Free Embedded RTOS

Just FYI: I wanted to know what was explained in this thread. I checked the docs for chSchRescheduleS and it didn't explain it one bit. Something like: This call is necessary if you call XXX or YYY from thread context, if a reschedule becomes necessary in ISR context, the reschedule is done automati...

Hi, I'm working on an STM32F303RB currently and I'm trying to get the ADC running. I can trigger the ADC once using my commandline-command. Now I want to trigger it 40k times per second (or less we'll see) from the pwm/timer callback. I could probably setup and automatic trigger to let the hardware ...

If that didn't work on first try I'd disable the watchdog until I have my current debugging-session done. Or are you debugging something related to the watchdog?

He is not in memory mapped mode. Or at least trying not to use it.

Another way to debug this might be with data breakpoints. Not sure if you can trigger on a region... A quick research session hints at: no ranges allowed.

On a slightly related note... On older chips, you could program an already-programmed word to something that was bitwise smaller. So for example you could do 0xffff -> 0xfff3 -> 0xfff0 -> 0xff00 -> 0xf000 -> 0x0000. On these chips the specs say that the only allowed "reprogramming" is to v...

HI, I'm saving a few parameters in flash (in this case normally only updated once when being installed in the field). Then I encountered this Heisenbug. With debugging enabled it worked, when disabled it didn't. Turns out its that one delay that does the trick... (the debug code is if (debug) {chpri...

The way I read it, you can also map a memory region as memory in the chip connected through QSPI. i.e. you just access memory at 0x...something and the hardware will push out a QSPI read cycle, wait for the results and sends off the CPU with the result when its done. Loads of waitstates, but for sca...

I understand that "not having hardware" is a problem. I just don't understand why you can't accept "let me send you some hardware then" as a solution ?

I think that this is the nucleo that ST thinks should cover the 'G030 as well. https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mcu-mpu-eval-tools/stm32-mcu-mpu-eval-tools/stm32-nucleo-boards/nucleo-g031k8.html I have posted my current diff here: https://prive....
