contain a copy of Rockbox 3.2 in the main image. It can easily be updated/replaced
later.
The bootloader allows to select which image to run. Pressing F1 at boot selects the
first image. F2 selects the second image, which will also be booted if you don’t press
any button. The button mapping is only there for completeness. F3 selects the built-in
serial monitor called Minimon. You should know this in case you invoke it by accident.
Minimon won’t display anything on the screen. To get out of it, perform a hardware
shutdown of your player.
12.5.3 Initial Flashing Procedure
You only need to perform this procedure the first time you flash your Recorder. You may
also want to perform it in case the update procedure for the second image recommends
it. In the latter case do not perform the steps listed under ”Preparation”.
Preparation
First, check whether your Recorder is flashable at all. Select System → Debug (Keep
Out!) → View HW Info. Check the values in the line starting with ”Flash:”. If
it shows question marks after ”M=” and ”D=”, you’re out of luck, your player is not
flashable without modifying the hardware. You can stop here. Sorry.
If your player is flashable, you should perform a backup of the current flash ROM
contents, in case you want to restore it later. Select System → Debug (Keep Out!)
→ Dump ROM contents. You’ll notice a few seconds of disk activity. When you
connect your player to the PC afterwards, you’ll find two files in the root of your player.
Copy the 256KB-sized file named internal rom 2000000-203FFFF.bin to a safe place.
Flashing
1. Download the correct package for your player from http://download.rockbox.org/
bootloader/archos/. It is named flash-<model>-<version>.zip. The current
packages are v3.
2. Unzip the flash package to the root of your player. This will extract two files
to the root, firmware <model>.bin and firmware <model> norom.bin. (The
<model> part is slighty different from that in the .zip file name.) The flash
plugin will select the correct one for your player. Now safely disconnect USB.
3. Make sure your batteries are in good shape and fully charged. Flashing doesn’t
need more power than normal operation, but you don’t want your player to run
out of power while flashing.
4. Select Plugins → Applications, and run the firmware flash plugin. It will
tell you about your flash and which file it is going to program. After pressing F1
it will check the file. If the file is OK, pressing F2 will give you a big warning. If
