ChibiOS Free Embedded RTOS

Hi Giovanni,

I've actually been struggling with this peripheral for a work project as well I was just looking through your code and saw that most things lined up with what I've been doing but saw one difference during init that was particularly tricky when I was bringing it up.

I found that if I ...

I'm still holding out for flash filesystem support This is something that would be a distinct differentiator from other current offerings, and would just happen to make my life a bit easier!

One other thing that would be nice: a simplified project structure (somehow)...not sure how this would work ...

Sounds like fun It might be interesting to have a visualization of the thread profiling information as well.

I also noticed in some recent commits to openocd that there is preliminary support for RTOS integration (including thread names, etc). It's not clear when they're ever going to make another ...

Looks like the interrupt was not getting cleared, so it was constantly re-triggering as you suspected. By reading the timer/counter status register, the interrupt source is cleared and processing proceeds as normal - problem solved. So, now my slightly modified code looks like:

static CH_FAST_IRQ ...

OK - I'll dig into it a bit further. Thanks!

Hi Giovanni,

I've tried that as well - at the highest level, I see the same result: the ISR seems to function OK, but my main task no longer runs (ie, the LED no longer blinks). Is there any other integration that needs to happen to allow normal systick handling to proceed? Thanks!

Hi, I'm getting some fast interrupt handling into my ChibiOS project (SAM7X256/GCC), but am running into a little trouble. I'm setting up one of the timer/counters to be routed through the FIQ.

I have the interrupt working OK - I can increment a counter indefinitely - but the rest of the OS doesn't ...

Woops - I obviously didn't look closely enough. Sorry for the noise!

A thought about the 'state' member variables in many of the HAL driver models structs.

In some cases (at least for GPT), the state variable is only used within chDbgAssert() to validate the drivers' state. If this is the case, one small optimization might be to only define and manage the ...

Hi Cyrille - the same error was reported above. Please take a look at the previous responses, and hopefully you should be able to resolve the issue.
