Jens Arnold cfb073c452 Coldfire: New timer handling on CPU frequency change, adjusting the prescaler on the fly, for both tick and user timer. Precondition is that the higher frequencies are integer multiples of the base: now NORMAL is 45 MHz and MAX is 124 MHz. Removes the need for applications with longer timer periods (>= 10 ms) to boost the CPU all the time, e.g. the grayscale lib. Timer counts are now always based on the base frequency (CPU_FREQ). * Adjusted the RAM refresh timers to the new frequencies (all frequencies for H100) * All: Fixed the tick timer count being off by one.

docs Workaround for ALAC files that previousy wouldn't play. Libalac now skips unknown chunk IDs. Time display and seeking is broken for those files (the ones that played before still work). Patch by Alyssa Milburn. 2005-09-24 02:12:42 +00:00

Build Your Own Rockbox

1. Check out 'rockbox' from CVS (or extract a downloaded archive). You
   want to check out 'rockbox-devel' instead if you want the simulator
   code too (for trying out things on host before making target tests).

   (For more information about the simulator, read UISIMULATOR.)

   $ cvs -d:pserver:anonymous@www.rockbox.org:/cvsroot/rockbox login 
   $ cvs -z3 -d:pserver:anonymous@www.rockbox.org:/cvsroot/rockbox co rockbox

     or

   $ tar xzf rockbox.tar.gz

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

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. Make sure you have sh-elf-gcc and siblings in the PATH. Make sure that you
   have 'perl' in your PATH too.

   $ which sh-elf-gcc
   $ which perl

7. Run 'make' and soon the necessary pieces from the firmware and the apps
   directories have been compiled, linked and scrambled for you.

   $ make

8. Copy the archos.mod or ajbrec.ajz file to your archos, reboot it and
   *smile*.  Recent Rockbox versions need no reboots, just PLAY a new rockbox
   version and that'll be loaded and replace the currently running version.

   $ mount /dev/sda1 /mnt/archos
   $ cp ajbrec.ajz /mnt/archos
   $ umount /mnt/archos

Whenever the tools/configure script gets updated, you can make your makefile
updated too by running 'tools/configure update'.

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
