Re: [ECOS] Re: REDBOOT QUERY

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
