Rockbox
8927df4205
Original fix by Marcin: it had a problem because crt0 on imx233 is more complicated than many targets: since we use virtual memory, we first disable the MMU, then move the entire image (including init and itext stuff), then setup a temporary stack to setup the MMU. Only when the MMU is enabled, can we move the init and itext stuff to its right location and finally boot. This requires some trickery because: - the initial move copies everything, including init and itext - the stack overlaps with init and itext to reclaim space - the temporary stack cannot be the same as the main stack to avoid trashing the init and itext code, also it needs to be a physical address Change-Id: Ibaf331c7d90b61f99225d93c9e621eb0f3f8f2dc |

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.bz2
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 sh/arm/m68k-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 acquired with the rockboxdev.sh script in the /tools/ folder of the
source, or will have been included if you've installed one of the
toolchains or development environments provided at http://www.rockbox.org/
$ which sh-elf-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-fmrecorder
$ cd build-fmrecorder
$ ../tools/configure
$ mkdir build-player
$ cd build-player
$ ../tools/configure
