Hi,

who wants to review and/or test a serial Flash loader for the 68HCS12
(Motorola / Freescale) using Base64 encoding and running at 115kBits/s
withouth need for handshake?

A short preliminary description is at
http://www.oliverbetz.de/FlashLoader/FSFL.html

Any comments appreciated.

The code (PC: ANSI C, HCS12: assembler) has some crude parts at the
moment, therefore I don't want to release it to the public until it's
cleaned up and reviewed by somebody experienced.

There will be also a version with encryption, but I need some feedback
about the concept and possible vulnerabilities (will ask in
sci.crypt).

Oliver
