ChibiOS Free Embedded RTOS

I just added a fairly standard shell to my application, based on the STM32F4 Discovery MEMS example, unfortunately when I "exit" the shell it causes a hardfault when calling:


The PC for the hardfault is in chevents.c, chEvtSignalI(), in the first condition of the "if" (or possibly the previous line - I'm still getting used to interpreting hard faults!).

As far as I know I'm not listening for the event, I just used the same shell handling that polls for the shell being terminated, then respawns.

Any ideas what might be going wrong?

Hi,

Do you call shellInit() before using the shell? the only thing it does is to initialize that even source.

Hi,

Thanks, that fixed it! Sorry, I really should have read the demo code more thoroughly
