You need two things: You need two things:
\begin{itemize}
\item The first is a \playername. Be sure you're using the correct package,
they are different!
\item Second, you need an in-circuit programmable flash. \opt{recorder,recorderv2fm,player}{The older chips are not flashable.}\opt{ondio}{This should always
be flashable on Ondios, because Archos does itself provide flash updates for
these.} You can find out via Rockbox (\setting{Info $\rightarrow$ Debug $\rightarrow$ Hardware Info}). If the flash info gives you question marks (Flash M=?? D=??),
you're out of luck. The only chance then is to solder in the right chip
(SST39VF020), at best with the firmware already in. If the chip is blank,
you'll need the UART boot mod as well.
\end{itemize}
\subsection{Flashing procedure}
Short explanation: copy the \fname{firmware\_*.bin} files for your model from the
distribution to the root directory of your \dap, then run the
\fname{firmware\_flash.rock} plugin.
Long version, step by step procedure:
\begin{enumerate}
\item Completely install the Rockbox version you want to have in flash, from a
full \fname{.zip} distribution, including all the plugins, etc.
\item Back up the current firmware, using the first option of the debug menu
(\setting{Info $\rightarrow$ Debug $\rightarrow$ Dump ROM Contents}).
This creates 2 files in the root directory, which you may not immediately see
in the Rockbox browser. The 256kB-sized \fname{internal\_rom\_2000000-203FFFF.bin} one is your present firmware. Back both up to your PC. You will need them if
you want to restore the flash contents.
\item Download the correct package for you model. Copy one or two files of it to
your box: \fname{firmware\_*.bin} (name depends on your model) into the root
directory (the initial firmware for your model, with the bootloader and the
Archos image). There now is also a \_norom variant, copy both, the plugin will
decide which one is required for your box.
\item Enter the debug menu and select the hardware info screen. Check your flash
IDs (bottom line), and please make a note about your \opt{recorder,recorderv2fm,ondio}{hardware mask value}\opt{player}{ROM version}. The latter is just for our
curiosity, not needed for the flow. If the flash info shows question marks,
you can stop here, sorry.
\item Use the \opt{recorder,recorderv2fm}{\ButtonFTwo\ settings or }the menu (\setting{General settings $\rightarrow$ File view $\rightarrow$ Show files}) to
configure seeing all files within the browser.
\item Connect the charger and make sure your batteries are also in good shape.
That's just for security reasons, it's not that flashing needs more power.
\item Run the \fname{firmware\_flash.rock} plugin. It again tells you about your
flash and the file it's gonna program. After \opt{recorder,recorderv2fm}{\ButtonFOne}\opt{ondio}{\ButtonLeft}\opt{player}{\ButtonLeft} it checks the file. Your
hardware mask value will be kept, it won't overwrite it. Hitting \opt{recorder,recorderv2fm}{\ButtonFTwo}\opt{ondio}{\ButtonUp}\opt{player}{\ButtonOn} gives you
a big warning. If we still didn't manage to scare you off, you can hit\opt{recorder,recorderv2fm}{\ButtonFThree}\opt{ondio}{\ButtonRight}\opt{player}{\ButtonRight} to actually program and verify. The programming takes just a few seconds. If
the sanity check fails, you have the wrong kind of boot ROM and are out of luck
by now, sorry.
\item In the unlikely event that the programming should give you any error, don't
switch off the box! Otherwise you'll have seen it working for the last time.
While Rockbox is still in DRAM and operational, we could upgrade the plugin via
USB and try again. If you switch it off, it's gone.
\end{enumerate}
\nopt{player}{
Now the initial procedure is done. Since the second half of the flash is still
empty, there is ``just'' the Archos image starting when you reboot now. Not much
has changed yet. The Archos software starts a bit quicker than usual, then loads
Rockbox from disk. The fun really starts when you add Rockbox to the flash, as
described in the next section.

\note{You may delete the \fname{.bin} files now.}
\subsection{Bringing in a Rockbox build}
Short version: very easy, just play an \fname{.ucl} file like
\fname{rockbox.ucl} from a release or build:

marks, you're out of luck. The only option for
flashing if this is the case is to solder in the right chip
(SST39VF020), preferably with the firmware already in. If the chip is
blank, you'll need the UART boot mod as well.
\end{itemize} \end{itemize}
\subsubsection{\label{ref:FlashingProcedure}Flashing Procedure}
Here are step{}-by{}-step instructions on how to flash and update to a
current build. It is assumed that you can install and operate Rockbox
the usual way. The flashing procedure has a lot of failsafes, and will
check for correct model, file, etc. {}- if something is incompatible it
just won't flash, that's all.
Now here are the steps: Long version:
\textbf{Preparation} The second image is the working copy, the \fname{rockbox\_flash.rock} plugin from
this package reprograms it. The plugins needs to be consistant with the Rockbox
plugin API version, otherwise it will detect mismatch and won't run.

Have the Jukebox nicely charged to avoid
running out of power during the flash write. Keep the Jukebox plugged
into the charger until flashing is complete.
{\bfseries Rockbox developers using Linux will have to download it from there and compile
Backup } it. For Win32 and Cygwin the executables are next to the packages. The sample
program from that download is called \fname{uclpack}. We'll use that to compress
\fname{rockbox.bin} which is the result of the compilation. This is a part of the
build process meanwhile. If you compile Rockbox yourself, you should copy
\fname{uclpack} to a directory which is in the path, we recommend placing it in
the same dir as SH compiler.
Backup the existing flash content. This is not an essential part of the
procedure, but is strongly recommended since you will need these files
if you wish to reverse the flashing procedure, or if you need to update
the bootloader (as opposed to the firmware) in the future. Keep them
safe!
Access the main menu by pressing F1 then select \textbf{Info Here are the steps:

your Jukebox now should contain two strange .bin files. Copy the larger
one named
\textbf{internal\_rom\_2000000{}-203FFFF.bin}
to a safe place, then delete them both from the box.
{\bfseries \begin{enumerate}
Copy the new flash content file to your box } \item Normally, you'll simply download a \fname{.zip} distribution. Copy all the
content to the USB drive, replacing the old.
\item Force a disk boot by holding \opt{recorder,recorderv2fm}{\ButtonFOne}\opt{ondio}{\ButtonLeft}\opt{player}{\ButtonLeft} during power-up, or at least rolo into
the new Rockbox version by \emph{Playing} the \fname{ajbrec.ajz}/fname{archos.mod} file. This may not always be necessary, but it's better to first run the
version you're about to flash. It is required if you are currently running
RomBox.
\item Just \emph{play} the \fname{.ucl} file in the \fname{.rockbox} directory,
this will kick off the \fname{rockbox\_flash.rock} plugin. It's a bit similar
to the other one, but it's made different to make the user aware. It will check
the file, available size, etc. With \opt{recorder,recorderv2fm}{\ButtonFTwo}\opt{ondio}{\ButtonUp}\opt{player}{\ButtonOn} it's being programmed. No need for
warning this time. If it goes wrong, you'll still have the permanent image.
\item When done, you can restart the box and hopefully your new Rockbox image.
\end{enumerate}
Depending on your model (recorder, FM, V2 recorder), download one of the You may find two \fname{.ucl} files in the \fname{.rockbox} folder. The
3 packages: classical, compressed one is \fname{rockbox.ucl}. If your model has enough flash
space left, there may be an additional \fname{rombox.ucl}, which is uncompressed
and can run directly from flash ROM, saving some RAM. The second way is the newer
and now preferred one. Use this if available.
\url{http://www.jens-arnold.net/Rockbox/flash_player.zip} If you like or have to, you can also flash the Archos image as the second one.
E.g. in case Rockbox from flash doesn't work for you. This way you keep the dual
bootloader and you can easily try different later. The \fname{.ucl} of the Archos
firmware is included in the package.
\url{http://www.jens-arnold.net/Rockbox/flash_rec.zip} \subsection{Restoring the original firmware}
If you'd like to revert to the original firmware, you can do like you did when
you flashed Rockbox for the first time. You simply use the backup files you saved
when flashing Rockbox for the first time and rename \fname{internal\_rom\_2000000-203FFFF.bin} to \fname{firmware\_*.bin} (name varies per model, use the filename that \fname{firmware\_flash.rock} asks for) and put it in the root.
\url{http://www.jens-arnold.net/Rockbox/flash_fm.zip} \subsection{Known issues and limitations}
Rockbox has a charging screen, but it is not 100\% perfect. You'll get it when
the unit is off and you plug in the charger. The Rockbox charging algorithm is
first measuring the battery voltage for about 40 seconds, after that it only
starts charging when the capacity is below 85\%.
\opt{recorder,recorderv2fm}{You can use the Archos charging (which always tops off) by holding \ButtonFOne\ while plugging in.}\opt{recorderv2fm}{Some FM users reported charging problems even with \ButtonFOne, they had to revert to the original flash content.}
\url{http://www.jens-arnold.net/Rockbox/flash_v2.zip} If the plugin API is changed, new builds may render the plugins incompatible.
When updating, make sure you grab those too, and ROLO or \opt{recorder,recorderv2fm}{\ButtonFOne}\opt{ondio}{\ButtonLeft}\opt{player}{\ButtonLeft} boot into the
new version before flashing it.
\url{http://www.jens-arnold.net/Rockbox/flash_ondiosp.zip} There are two variants of how the boxes starts, therefore the normal and the
\_norom firmware files. The vast majority of the \daps\ all have the same boot
ROM content, differentiation comes later by flash content. Rockbox identifies
this boot ROM with a CRC value of 0x222F in the hardware info screen. \opt{recorder,recorderv2fm}{Some recorders have the boot ROM disabled (it might be unprogrammed) and start directly from a flash mirror at address zero. They need the new
\_norom firmware that has a slightly different bootloader.}
Without a boot ROM there is no UART boot safety net. To compensate for that as
much as possible the MiniMon monitor is included, it starts with \opt{recorder,recorderv2fm}{\ButtonFThree+\ButtonOn}\opt{ondio}{\ButtonRight+\ButtonMenu}\opt{player}{\ButtonRight+\ButtonOn}.
Using that the box can be reprogrammed via serial if the first 2000 bytes of the
flash are OK.
\url{http://www.jens-arnold.net/Rockbox/flash_ondiofm.zip} \subsection{Download the new flash content file to your box}
Jens Arnold hosts flash content for download. Use the following url:
The zip archives contain two .bin files each. Those firmware*.bin files \opt{player}{\url{http://www.jens-arnold.net/Rockbox/flash\_player.zip}}
are all we want, copy them to the root directory of your box. The names \opt{recorder}{\url{http://www.jens-arnold.net/Rockbox/flash\_rec.zip}}
differ depending on the model, the flash \opt{recorderv2fm}{\url{http://www.jens-arnold.net/Rockbox/flash\_fm.zip},

This procedure is only necessary the first time you flash Rockbox.
Unplug the USB cable again, then select \textbf{Browse
}\textbf{Plugins}\textbf{ } from the main menu (F1). Locate \textbf{firmware\_flash.rock}, and start it with PLAY. Rockbox now displays an info screen, press F1 to acknowledge it and start a file check. Again wait for the disk to
settle, then press F2 to proceed to a warning message (if the plugin
has exited, you don't have the proper file) and F3 to actually program
the file. This takes maybe 15 seconds, wait for the disk to settle
again. Then press a key to exit the plugin.

{\bfseries
\label{ref:FlashingRockbox}Install the Rockbox binary in flash}
All the above was necessary only once, although there will not be any
obvious difference (other than the Archos firmware loading a bit more quickly)
after the step above is complete. Next install the actual Rockbox firmware thatwill be used from ROM. This is how Rockbox will be updated when
installing a new release from now on.
\begin{itemize}
\item Unpack the whole build that you are installing onto the Jukebox,
including plugins and support files. This can be done using the Windows setup program to install the new version onto the Jukebox.
\item Test the build you are going to flash by playing the .ajz file so
that ROLO loads it up. This puts the firmware in memory without
changing your flash, so you can check that everything is working. If
you have just installed the bootloader (see above) then this will happen automatically as the existing Archos firmware loads the .ajz that you have just installed. If upgrading ROMbox, this step \textbf{must }be carried out since Rockbox cannot overwrite the ROM while it is running from it.
\item Play the .ucl file, which is usually found in the
\textbf{/.rockbox} directory, this will kick off the
\textbf{rockbox\_flash.rock} plugin. It's a bit
similar to the other one, but it's made different to
make the user aware. It will check the file, available size, etc. With
F2 it begins programming, there is no need for warning this time. If it
goes wrong, you'll still have the permanent image.

UCLs for the latest Recorder and FM firmware are included in Rockbox 2.4
and also the daily builds.
\subsection{\label{ref:KnownIssuesAndLimits}Known Issues and Limitations}
There are two variants as to how the Jukebox starts, which is why there
are normal and \_norom firmware files. The vast majority of Jukeboxes
all have the same boot ROM content, but some have different flash
content. Rockbox identifies this boot ROM with a CRC value of 0x222F in
the hardware info screen. Some recorders have the boot ROM disabled (it
might be unprogrammed) and start directly from a flash mirror at
address zero. They need the \_norom firmware, it has a slightly
different bootloader. Without a boot ROM there is no UART boot safety
net. To compensate for that as much as possible the MiniMon monitor is
included, and can be started by pressing F3+ON. Using this the box can
be reprogrammed via serial if the UART mod has been applied and the
first \~{}2000 bytes of the flash are OK.
\subsubsection{ROMbox}
ROMbox is a flashable version of Rockbox that is
uncompressed and runs directly from the flash chip rather than being
copied into memory first. The advantage of this is that memory that
would normally be used for storing the Rockbox code can be used for
buffering MP3s instead, resulting in less disk
spin{}-ups and therefore longer battery life
Unfortunately being uncompressed, ROMbox requires more space in flash
than Rockbox and will therefore not fit in the space that is left on an
FM recorder. ROMbox therefore runs on the V1 and V2 recorder models
only.
The procedure for flashing ROMbox is identical to the procedure for
flashing Rockbox as laid out on page \pageref{ref:FlashingRockbox}.
The only difference is that the file to install is called
