eCos interrupts (PIE in status register =0)

Altera_Forum · ‎03-25-2013

Hi all,

my (timer) interrupt didn't work until I figured out, that bit 0 (PIE) in

the status register is set to 0.

So after all of my initialization stuff is done, I set that bit to 1.

The system works, however any program interruption through gdb frontend

is end of story - gdb frontend says "trap" and can't find

the proper breakpoint address then.

It is quite possible that I something messed up, as during

investigation of the problem I added some assembly

to eCos HAL (LED blinking in vectors.S).

My solution is rather hack so my question is,

is there a _clean_ way to enable global interrupts on eCos?

Note that I use eCos from github & zylin howto.

Thanks,

Michal

Learned the hard way that the cyg_user_start() isn't the right

place for my application.

Interrupts and thread scheduler are automatically started

after cyg_user_start() exit...
