ChibiOS Free Embedded RTOS

the linaro toolchain is a bare metal toolchain. I am also using the toolchain you linked on a different computer and I was still getting the same problem.

I ended up disabling autostart on that interrupt channel. I added extStartChannel... after all of my initialization code and voila! No more ...

Ah, I tried toggling a pin and setting breakpoints.

Toggling the pin showed that there is an interrupt at the very beginning.

The odd part: when I put the breakpoint in that first spurious interrupt disappears and the program works correctly!

I am using the linaro gcc toolchain. Could it be a bug ...

I am writing a driver for an IC that pulls a line low to signal that it has data that needs to be read.

I have my code set up to interrupt when that line is pulled low which sends a signal via chEvtSignalI to a thread that has a chEvtWaitAny followed by the spi commands to read from the IC.

For ...

Ah, wonderful! I set optimizations to 0 as suggested and everything works fine now. It wasn't just the debugged that was acting up though. I have a LA hooked up to my dev board and it wasn't acting correctly either.

Thanks for the help Giovanni!

That is actually one of the two compilers I have tried using (gcc-arm-none-eabi).

Hi,

I've searched and searched and asked on irc channels and I haven't been able to figure out a problem I'm having with my code. I don't think it is related to chibios, but this is probably as good a forum as any to ask.

I'm running Chibios 3 and I've compiled by code both on the default fedora ...

Do you still want feedback on the book?

I will happily read over it and try to give advice.
