[ECOS] GPIO blinking

[ECOS] GPIO blinking

[Nickolay]

Hallo.

I'll try load redboot on new hand worked IXDP425 board, but has some 
problem.
The prefect way to debug where problem is, turn on/off some GPIO leds.
Can anyone can tell me, how i can turn on/off GPIO?
I discovery, that redboot start running from cyg_start() function, and 
then i wanna
insert code for GPIO blinking after each instruction in that file.

Hi,

I havent done led blinking .. 
but I think it shouldnt be that tough ..  u can call the GPIO_HIGH ,
etc macros which are there in the whole code .. that should take that
specific GPIO high and if ur LED is on that GPIO, it should blink ..

I am not too sure first of all how come default image u have made isnt
working on IXDP425, I am also using IXP425 based board .. and it works
fine for me with default compilation on IXDP425,
may be u can post something on that here and we can try and help u with that .. 

Cheers,
Alfred
