UNTESTED, could ver well brick your Clip+ If it works, booting should just be delayed by a small delay (perhaps not noticeable) Hopefully the Clipv2 checks will work for Clip+ and then we'll be able to test the other Clipv2 code (LCD/button) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@24219 a1c6a512-1295-4272-9138-f99709370657

|
|

A tool to inject a bootloader into a Sansa V2 (AMS) firmware file.

|
Usage
|
|
-----
|
|
|
|
mkamsboot <firmware file> <boot file> <output file>
|
|
|
|
<firmware file> is an original Sansa firmware file obtained from the Sansa
|
|
forums for example : http://forums.sandisk.com/sansa/?category.id=devices
|
|
|
|
<boot file> is the code you want to execute (a rockbox bootloader), previously
|
|
scrambled with tools/scramble utility.
|
|
|
|
<output file> is the resulting firmware file which you'll have to copy on your
|
|
Sansa player. See "Firmware filenames".
|
|
|
|
|

For the firmware upgrade to happen, the firmware has to be named specially:

|
|
clip : m300a.bin
|
|
clip+ : clppa.bin
|
|
fuze : fuzea.bin
|

|
Dual-Boot
|
|
---------
|
|
|
|
The purpose of this program is to provide dual-boot between the original
|
|
firmware and the new (rockbox) firmware.
|
|
|
|
By default the player will boot into the new firmware.
|
|
|
|
To boot into the Original Firmware, you need to press the Left key.
|
|
***Note : on the c200v2 you need to press the Right key.
|
|
|
|
The player will boot into the Original Firmware as well if it is powered up by
|
|
inserting an usb cable.
|
|
***Note : on the m200v4 powering up by usb will cause booting into the new
|
|
firmware
|
