Dave Chapman c2933cd46e Remove the dependency on sufficient free space in the padding at the end of the firmware block by storing the ucl unpack function in the main firmware block, immediately before the compressed firmware image. Also simplify the memcpy function in test.S. This has been tested successfully on a Clip. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18682 a1c6a512-1295-4272-9138-f99709370657		2008-10-02 12:37:47 +00:00

I repeat: This is UNTESTED and needs reviewing fully before attempting to install on a device.	2008-10-01 09:15:44 +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".
