13.4. Firmware Loading
When your player powers on, it loads the Archos firmware in ROM, which automatically
checks your player’s root directory for a file named ajbrec.ajz. Note that Archos
firmware can only read the first ten characters of each filename in this process, so do not
rename your old firmware files with names like ajbrec.ajz.old and so on, because it is
possible that the player will load a file other than the one you intended.
13.4.1. Using ROLO (Rockbox Loader)
Rockbox is able to load and start another firmware file without rebooting. You just
“play” a file with the extension .ajz. This can be used to test new firmware
versions without deleting your current version.
13.5. Rockbox in Flash
13.5.1. Introduction
When you bought your Recorder, it came with the Archos firmware in flash ROM.
When you power on your player, this Archos firmware starts, and then loads an updated
firmware from disk if present (ajbrec.ajz). An ordinary Rockbox installation only
replaces the on-disk firmware, leaving the flash ROM contents intact. That means the
Archos firmware still controls the boot process.
The main reason to change this is to improve the startup time of your player. The
Archos bootloader is rather slow. With Rockbox in flash, your player will boot much
faster, typically in three to five seconds. Furthermore you might prefer a clean Rockbox
environment, with as little remnants of the Archos software as possible.
Warning: Flashing your player is somewhat dangerous, like programming a mainboard
!
BIOS, CD/DVD drive firmware, mobile phone, etc. If the power fails, the chip breaks
while programming or most of all the programming software malfunctions, you’ll have a
dead box. We take no responsibility of any kind, you do that at your own risk. However,
we tried as carefully as possible to bulletproof this code. There are a lot of sanity checks.
If any of them fails, it will not program.
