Michael Sevakis a36a498c57 i.MX31/Gigabeat S: This should fix stability problems. One problem was to start using the DVFS controller properly so that interrupts will be masked at the lowest and highest frequency indexes. Millions of useless interrupts were occurring at 132MHz because its index was 2, not 3, which masks it automatically when it can't go slower. Stopping the flood was enough to actually see the difference in general. IRQ must be disabled when fiddling with the CCM registers and only enabled when waiting for voltage ramp as having them enables also causes spurious DVFS ints. Implement interruptible ISR pro/epilogue more safely (always using IRQ stack even in SVC mode handling). Fix an improper inequality in DVFS code (which set regs for down when going up and v.v.). Misc. support changes. Have internal tables take less RAM.

flash Simplify powermgmt thread loops so it calls functions turn (no more power_thread_sleep). Do other target-friendly simplifications, generic battery switch handling and split sim-specific code. Whoever can, please verify charging on the Archos Recorder (due to change in the charger duty cycle code). 2008-12-24 16:58:41 +00:00

Build Your Own Rockbox

1. Check out 'rockbox' from SVN (or extract a downloaded archive).

   $ svn co svn://svn.rockbox.org/rockbox/trunk 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
