1. You need a FLASH programmer, capable of preogramming the Atmel 29LV1024 chips.
   (At least that's what's on my machine).
2. Somehow, either by programmer magic or programmatically, you need to split the
   binary image up into two halves.  One FLASH will get bytes 0,1,4,5,8,9,...
   while the other gets 2,3,6,7,10,11,...

That's about all there is to it.  The FLASH devices end up in sockets U35, U45.

Hello,
i worked also with brutus. If you has a running angel on brutus, then you can make a
small program header for your program. This header has to be linked as the first part
of your program. It is only uses for the angel debugger to identify the file format.
The header itself has no functionality. But now you can use the angel development
tools to download your binary image and burn it into flash (using the fmu - sample).
Select the switches for starting user image and angel starts your program. If you
need more information, please use 'cc Roman.Jordan@planet-interkom.de'. I will try to
check, what i have done some weeks ago.

greetings from germany,
