[ECOS] help:problem running ecos application

Hi all,
Im trying to run a simple eCos application in target RAM. When I try to 
load the executable through GDB it fails to load .text section to LMA 
0x0080 0000 (Ext.RAM base address) with msg "packet 
error,continuing...". Im presuming that this is an illegal operation 
since RedBoot_ROM would have copied the VSR table to this location 
(correct me if mistaken). Does anything look suspicious here?

eCos was configured for RAM startup, inherit  console settings. Target: 
PhyCore555. Thanking in advance.

Regards,
Rohit
