Bootloader Installation

Disclaimer: Rockbox is not in a usable state yet. Unless you know what you're doing AND interested in getting the port forward by contributing to the project, please reconsider installing the bootloader again, and once more. Even though the bootloader installation is tested, there's always a fair risk of rendering your device useless. Again: There's no known recovery method which works on all AMS Sansas. We are not responsible for any damage your device takes during this procedure. Also, bootloader installation has been confirmed to permanently disable DRM support on the e200(to be investigated on other targets).

Building the bootloader consists of three parts: Building the actual bootloader, patching a OF file with the bootloader using mkamsboot, and putting the firmware file on your device so that the standard firmware update mechanism installs the patched firmware.

You build the Rockbox bootloader using tools/configure. You then pass the created bootloader file (which should be named like bootloader-{device}.sansa) and a OF file of your choice (that fits your device of course) to mkamsboot. To do so, copy the bootloader file and the OF to rbutil/mkamsboot/, cd to that location and execute mkamsboot {firmware file} {boot file} {output file} (e.g. mkamsboot fuzea.bin bootloader-fuze.sansa patched.bin). Note: You may need to type make before to build mkamsboot. Finally you copy the output file to your device, using the same filename as the input file had.
