custom mpc8240 student project (long)

[Ron Bianco]

My $.02:

Why don't you just use a regular old EPROM to hold your ppcboot monitor image.?
IIRC, it has a serial driver and provision for downloading linux kernels to
SDRAM.
I'm not sure if it has provision for R/W of flash, but maybe.

You're planning to run at a very low clock speed on your wire-wrapped board.
Ugh!
Better check the 8240 datasheet, there may be lower limits to what's allowed.

You'll be very handicapped by not having a BDI2000, which, BTW, uses JTAG port
for fast downloads to SDRAM.
Surely your school has a budget for development tools?  The BDI would have other
uses besides just your 8240 project.

Good luck, Ron
