[ECOS] Some irregular issue in redboot

[<madhusudhan dot gowda at wipro dot com>]

Hi,

The error  "Err 92 Can't program at region 0x50080000" is 
doesn't occur anymore and we are able to load the images properly (
kernel and cramfs image ) "version 1.92 - built 17:43:07, Oct 20 2003".

But sometimes when we try to access some of the web pages ( our coyote
board has a web server running ), it does not respond at all 
and the interface ixp0 on the coyote board hangs . That is you cannot
ping the IP address of ixp0 as well as ping from ixp0 to other machines.
basicallly ixp0 interface fails to receive and send any packets
The command ifconfig ixp0 down also hangs 
Only way to recover from this is to reset the coyote board
This issue occurs occasionally and is seen only with J3C flash  ( No
such issues when we use J3A flash )
 
It will be helpful if someone could let us know whar may be the issue
still with J3C flash ?
Do you suspect that there might be issues still in reading / writing
from / to the flash ?

Whereas release note says that there is a still newer version of redboot
( Dec 15, 2003 build )
Will this make a difference for the above issue ?

 I'am also pasting the output of Redboot "fis list" command for your
reference and also the Redboot release note.
