[ECOS] Beginner Question: Porting eCos to Beagleboard

[Tatu Tolonen <tjtolon1 at cs dot hut dot fi>]

Hello Everyone,

I've been given a task to install a working eCos to Beagleboard with 
u-boot bootloader from memory card and now I've come to a dead end. As 
eCos still doesn't have support for Beagleboard, OMAP3530 or even 
Cortex-A8, I tried using different packages (I heard that ARMv6 is like a 
subset of ARMv7 instruction set). As one can imagine, I failed.

Previous mails in this mailing list didn't give a clear image, is this 
task even possible, has someone succeeded using eCos on Cortex-A8. So now 
I assume no one has done it and now I would have to make a proper port for 
it.

Is porting difficult? Can it be done in a time span of few days/weeks when 
it's done by one person without prior knowledge of the target or the OS? 
Porting Guide from eCos reference manual seemed somewhat straightforward, 
but as usual, 90% of effort goes to 10% of tasks, which are invisible from 
documentation.

Best Regards,
Tatu
