ChibiOS Free Embedded RTOS

Giovanni I'm sorry to bother you again with this. But I'm having another but similar problem now.

I've updated my chibios yesterday (r10155). It seems mailbox implementation has been recently changed. Now I get a priority violation after a call to `chMBPostS` from a lock zone. My understanding was ...

Thank you. That's a load off my mind.

I'm going to enable all checks from now on : )

Hi Giovanni, I think I've found the source of problem. I didn't observe the problem when I added `chSysLockFromISR` to my problematic ISRs. But I'm not sure if this is what fixed it.

I have been signaling semaphores from interrupt callbacks. But I did not use `chSysLockFromISR`. Different threads ...

Stack traces are not useful.

Ok, I will try to put together a clean code to reproduce the issue then.

When you said priority above 2 did you actually meant "smaller number than 2"? The only interrupts I'm dealing with are peripheral interrupts timer, EXTI, SPI etc. And those all have bigger than ...

Hi Giovanni, thanks for your reply.

I'm not eager to post the source code since it's quite messy : ) But I can show you a call trace of where it always crashes:

As you can see above, it always crashes when waking from a specific semaphore (with msg ...

Hi I'm having a crash in `chSysUnlock()` function due to "priority order violation".

There were a few cases of improper use of I-class functions from lock zone in my code. I fixed those by adding `chSchRescheduleS()` right before unlocking. But problem continues. I was wondering what else might be ...

Hi Giovanni, from documentation it is not apparent that `extSetChannelMode` also enables the channel. That caused frustrating moments for me : ) until I read the source code. It would be nice if you could add this as a note.

I got it again. This time I noted the IP address.

blocked: 46.166.188.232

After I disconnected, and re-connected to VPN, I wasn't blocked and my IP was this:

not blocked: 46.166.190.222

I've tried it a couple times to make sure problem is related to that IP address above.

By the way I figured ...

It was both website and forum.

Interestingly at the moment I can access via VPN. I'm using PIA. I think my IP has changed. I note my IP address next time I have problem.

Hi, I cannot access to chibios site when I'm connecting via VPN. Website doesn't load at all. No warning no captchas. I'm okay with captchas. I'm a master of captchas by now : ) For some of us, VPN is essential for a proper internet connection. Git protocol access is always disabled in my university ...
