[Avila] RedBoot partition corrupted with bad image;

[Ron Eisworth]

Bhanu,
Unfortunately it sounds like you will need to use a JTAG programmer to
reflash the standard Gateworks image.=20

Gateworks offers a JTAG programmer as part of their development kit or =
you
can buy one as a separate item.=20

Regards,

Subject: [Avila] RedBoot partition corrupted with bad image;=20
Subject: [Avila] My redboot partition got corrupted with my experiments to load custom =
build
redboot.

I copied the RedBoot image from Linux using /dev/mtd0. The bad part is =
that
the two boards I have, got RedBoot partition screwed.

1.	How can I make my board come alive?

2.	My board allows loading through http, tftp, and serial but not
from disk. I tried to load RedBoot using xmodem but got strange =
characters.
Ethernet was also not accessible as the NPE drivers were not properly
integrated with RedBoot. How can I successfully load the redboot =
(ROM/RAM
images) using serial, since I don't have JTAG?

4.	I tried to load SnapGear image on the board through xmodem so
that I can manipulate mtd0; but failed to load snapgear image.

SETUP -
Avila GW2348-4-A
16MB Flash
IXP425
RedBoot 2.02
SnapGear 3.4.0
