History

Dave Chapman 2c096e463d It turns out that in-place UCL decompression isn't as easy as we thought, so we copy the OF to an unused part of RAM before decompressing it. This works - I have successfully patched m300a-1.1.17A.bin and installed on my Clip with this code. Thanks to Rafael Carre (funman) for the actual patch. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18679 a1c6a512-1295-4272-9138-f99709370657		2008-10-01 23:19:14 +00:00

README

This directory contains the following tools related to the Sansa V2
(AMS) firmware files:

1) amsinfo

A tool that dumps information from an AMS firmware file.

2) mkamsboot

A tool to inject some code (contained in test.S) into a firmware file.

Edit the INFILE variable in the Makefile to point to the original
firmware file you want to patch, edit "test.S" appropriately, and then
type "make".
