Subject: Update: Rockbox running directly from flash rom (ROMbox)
From: Jens Arnold (arnold-j_at_t-online.de)
Date: 2004-07-30


Hello all,

I updated my ROMbox builds to the latest cvs, enabling the use
of the splitedit.rock if used in conjunction with a daily build
of 2004-07-30 or later. (In fact, it re-enables the use of all
plugins, since the plugin api has changed in an incompatible way
since the last ROMbox builds were released.

For your convenience, the instructions are included again.

Btw: Did no one dare to try this out on a V2 recorder yet?
I really would like to know if it works for these as well.

I use ROMbox on my V1 recorder all the time, and I didn't find
any problems with it so far.

Note to V2 users: The V2 version of Rombox is untested, and
compiled "blindly" based on the info stated by Jörg, so there
is a slight chance that Rombox won't boot on the v2. However,
the safety net (F1+On boot into Archos firmware) is there as
usual.

** Requirements:

            Archos Jukebox Recorder _V1_, flashed
OR (REALLY) Archos Jukebox Recorder _V2_, flashed

(The Player/Studio isn't currently flashable, and for the
FM Rombox won't fit in the remaining ROM space. This will
most likely change if this test proves that running from rom
is really useful)

** Procedure: (Recorder V1 / V2 ONLY!)

- Download & install a daily build of 2004-07-30 or later.
- Download the ROMbox version for your box
  V1: http://arnold-j.bei.t-online.de/Rockbox/rombox-recorder.ucl
  V2: http://arnold-j.bei.t-online.de/Rockbox/rombox-v2.ucl
  and copy it to your box as well
- RoLo into the daily build.
- flash rombox-recorder.ucl (V1) or rombox-v2.ucl (V2)
  respectively
- If flashing went ok: switch off the box and start it again
- Look into Info->Rockbox Info. The buffer value should be
> 1.790 MB (It reads 1.798 MB for me. I have the number of files
  per dir set to 300, and the maximum playlist size to 5000)

Play around with it as you would do with ordinary rockbox, and
report if anything doesn't work as expected. (Expected means
like ordinary rockbox). The only exception is the flash
plugin, see below.

Do _not_ delete ajbrec.ajz. You'll need to RoLo into it if you
want to flash another .ucl later, as you can't flash the ROM
if Rockbox is running from it. The flash plugin should tell
you that you are running from ROM and refuse to flash if you
try that.

If you want to do even more, you could do runtime tests,
comparing rombox runtimes with ordinary rockbox. I'm
especially interested in runtime tests with a Recorder v2.

Regards, Jens
