On the Echo R1, the main regulator is enabled primarily by the power button and USB input, and secondarily by the CPU's own output pins (cpu_power_on signal or RTC alarm output). From a user perspective, the player should appear to power up and down only if the power button is long pressed, which must be implemented in software. These logical power states are called "active" and "inactive" in the bootloader. Going from inactive to active will attempt to boot Rockbox unless a button (d-pad down) is held to enter bootloader USB mode instead. Going from active to inactive will shut down the player. The bootloader will also automatically shut down after a short timeout, if USB is not plugged in. In the inactive state, the player is supposed to enumerate over USB so it can negotiate a charging current, but should otherwise appear "off". In particular it shouldn't expose mass storage or even power up the SD card, nor power up the LCD/backight. This isn't implemented yet, because there's no way to dynamically change USB configurations (eg. going from active to inactive should trigger re-enumeration to switch to charge only mode). To avoid surprising behavior, the bootloader will just boot Rockbox immediately if USB is plugged in at boot. Change-Id: Icd1d48ef49a31eb32b54d440e9211aaf40c6b974 |

Build Your Own Rockbox
1. Clone 'rockbox' from git (or extract a downloaded archive).
$ git clone git://git.rockbox.org/rockbox
or
$ tar xJf rockbox.tar.xz
2. Create a build directory, preferably in the same directory as the firmware/
and apps/ directories. This is where all generated files will be written.
$ cd rockbox
$ mkdir build
$ cd build
3. Make sure you have mips/m68k/arm-elf-gcc and siblings in the PATH. Make sure
that you have 'perl' in your PATH too. Your gcc cross compiler needs to be
a particular version depending on what player you are compiling for. These
can be generated using the rockboxdev.sh script in the /tools/ folder of the
source.
$ which arm-elf-eabi-gcc
$ which perl
4. In your build directory, run the 'tools/configure' script and enter what
target you want to build for and if you want a debug version or not (and a
few more questions). It'll prompt you. The debug version is for making a
gdb version out of it. It is only useful if you run gdb towards your target
Archos.
$ ../tools/configure
5. *ploink*. Now you have got a Makefile generated for you.
6. Run 'make' and soon the necessary pieces from the firmware and the apps
directories have been compiled, linked and scrambled for you.
$ make
$ make zip
7. unzip the rockbox.zip on your music player, reboot it and
*smile*.
If you want to build for more than one target, just create several build
directories and create a setup for each target:
$ mkdir build-fuzeplus
$ cd build-fuzeplus
$ ../tools/configure
$ mkdir build-xduoox3
$ cd build-xduoox3
$ ../tools/configure
