Re: [ECOS] Configure Network Support for eCos

["Ruchika Singh" <rusingh at ecs dot umass dot edu>]

Hi:

I am still trying to work out the network configuration.
I have updated to the latest eCos version, put the problem still remains.

My hardware platform is not directly supported by eCos. Its a BRH board by 
ADI Engg, that addeded their own support for brh on eCos/Redboot source code.
They claim only however, Redboot's support for Networking, not paticularly 
for eCos applications that would run on board.

So, I have this basic questions:

1. If anyone has used eCos on brh board, with networking support? 

2. I am wondering if ethernet driver support for eCos applications and 
Redboot could be different? Perhaps my hadware only has driver support for 
redboot.?( and hence eCos application can't find MAC address etc when 
Redboot is able to find it) I am not sure if the two are different though. 
If yes, any insight/pointers into how I can modify it to support eCos 
applications as well?

I am a newbie to eCos. I would really appreciate any insights into this 
problem..have been stuck for a while!

Thanks
-R.
