Howto install bootloader using jtag?

Howto install bootloader using jtag?

[Nitesh Goyal]

Hi,
I'm using a IBM PPC 405GP board(from embeddedplanet) I accidently
deleted the bootloader.

I have the bootloader srecord image on my host, but I do not know how to
burn it on board using JTAG ?

Is there a utility available that I can use on host to download the
bootloader image to tbe board ?

Thanks,
NItesh

Depending on what JTAG debugger you're using, there should be a way to
download and execute the S-Rec file (usually a .mot file). The bootloader
file provided by Emdedded Planet is actually an executable that contains the
boot loader image. You should be able to download and execute it in one
simple step.

The first thing you do is create an appropriate config file for the debugger
and board.  If you go to ftp://ftp.denx.de/pub/BDI2000/ you can get Abatron
BDI config files for the ep405 board.  You run this script then download the
pcl____.ep file that is on the documentation CD.  This file executes at
location 0x100000 and will burn the bootloader into flash.

It is important to note that the JTAG/COP connector on the ep405 ships with
the COP enabled, not the JTAG.  There is very little difference between JTAG
and COP but this can mess people up under certain circumstances.  I have
used the Abatron BDI 2000, Macraigor RAVEN, Macraigor OCDemon and the IBM
RiscWatch.

I have downloaded the script(config file) on my host machine (x86). How do I run the script ? If I am right, it has to be run on the board, but the problem is, I can't communicate to the board with serial-port.

The problem is I do not know how to download an image from the host to the board because I've overwritten the bootloader.

Also, if I'm right, the JTAG has to be connected to the parallel port of host and the bootloader image needs to be downloaded using "some" utility ?

TIA,
