Howto install bootloader using jtag?

[Steven Blakeslee]

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.

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.
