Hi port-arm,

Just a mail to sum up how to boot NetBSD current on ENP2611/Radisys
board for IXDP2400/xscale  perhaps it could help someone else or it
could be integrated later in the source tree. 

Currently,  I have problem with I82557(fxp0 driver) ethernet controller
for BOOTP request to mount root file system as a NFS.

my bootp reqesut coudnt go outside output interface.

below are mt ENP2611/IXDP2400 bootup messages

hang....

My questions are...

1) Is there any problem related to ethernet driver or hardwar problem?
2) i can see clearly in fxp driver that it used DMA operation rather
than IO or  memory operation..is it a problem related to DMA operation 
2) how to mount Flash file system for Ixp/xscale??

Thanks
