As it will always be, you will have to disassemble your AJB, unsolder
memory chips, solder on new memory chips, reassemble your AJB. At that
point, you will be able to turn on your AJB, enter USB mode, upload the
software, and finally reboot! Saving the recompililation step is 1% of the

Once you have the chips replaced, there is very little point in being able
to dynamically reconfigure your Rockbox software between 2MB and 8MB: if
you have a 8MB AJB you may want to go to 2MB for testing, but that will be
an unusual operation and you will undoubtedly be loading new software (the
target of your tests) anyway. If you have a 2MB AJB, you REALLY DON'T want
to change the configuration to use 8MB because it will not run (if you are
lucky) or it will wipe out your files (if you are unlucky) and could damage
your AJB (if you are really, really unlucky).
