Here's first one...

There are also unnecessary '&' mark before ISR function names in
call to cyg_intterrupt_attach() in "developing embedded systems with
ecos".

Examples, which I have found via google didn't help much for me.

Serious problem for me was finding 'the ecos way' to do some really
trivial task like capturing IRQ. If I compare time, which this took to
me with the same thing on QNX, then QNX wins -- there is very clear
explanation in thier docs, with example for clock interrupt, which
was running out-of-the box. Modifing it to meet my needs was few
minutes.

Things, which make most difficulties:
- use "CYGNUM_HAL_ISR_MIN + 3" insted of "3" as IRQ number,
- why I need threads to make it work,
- why HAL_READ_XXX doesn't have HAL_READ_XXX (port) prototype,
- why second argument isn't a pointer.
Thats weird for me...:(
