Hi,

Thank you both for your responses. But I have few doubts

1) How do u enable assertions in your build?

2) Yes I am getting both the redboot as well as eCos's address 
 from DHCP. I tried changing eCos's address to manual it did not 
work..

Will changing the card to 82559 help? Or I am missing any
configuration?

Thanks again.

Regards,

Kaustubh

Enabling CYGPKG_INFRA_DEBUG in ecos.ecc, or inside the infrastructure
package in the graphical config tool.

What didn't work? Changing the address caused some new failure (if so,
what?) or it didn't change the existing problem?

I doubt it's a card specific issue.

You should also enable assertions in your build as the driver does do a
fair bit of checking. And of course a standard thing to check: check you
aren't getting both RedBoot's and eCos's addresses from DHCP.

You need to track this call. My guess is that it calls into the 82559
driver, maybe i82559_start or i82559_init. You need to see what its
trying to do when it hangs and then work out what the 82558 does
differently than the 82559. At a guess its interrupt handling. Redboot
does polled IO, where as the 'real' driver is interrupt driver.

The load address of your program is 0x10000. This doesn't look right. If
this is eCos v1.3.1, then switch to anonymous CVS sources.
