RE: Integrator/uHAL

true, but it would have been nice to be able to use the uHAL timer
functionality though because it's very flexible.. We need to work with some
very fast
timer interrupts and the alarm functionality in eCos only works with 
big resolutions, so we can't use them for that.
Not using uHAL means that I will have to write some timer routines  
myself then, or am I wrong somewhere ?

I did a port to the Integrator before the official one came out. As eCos is
inextricably linked with the processor right down to low level interrupt
handling, and the services offered by the uHAL are essentially replicated by
the eCos HAL, device drivers and libraries, I saw little point in trying to
use the uHAL.
