Subject: RE: Ondio question
From: [IDC]Dragon (idc-dragon_at_gmx.de)
the Ondio has an internal 128MB memory, which is basically an MMC card on a
chip, firmly mounted. The control can be switched to an external MMC in a
slot. SD cards are thicker and don't fit into the slot, although the logic
which drives the card should be capable of SD as well.
Archos uses these memories mutually exclusive. If an MMC is plugged, you
don't see the internal any more. For USB operation, it certainly has to be
like this, because the USB<->MMC bridge chip can only talk to one card.
For Rockbox, it is imaginable to switch at runtime as desired, using the two
memories like 2 drives. But this is a new concept, so far only one HD was
supported, don't hold your breath for that.
Rockbox on Ondio will have the voice UI, no reason to drop that. Since flash
memory has no spinup time/power demand, it may even be better with "while
Because the transfer is much slower than from disk, I may have to change the
way the voice file is handled. Right now it is completely loaded into the
mp3 buffer (and has to fit there) when first used, to avoid later spinups.
This may be a big latency with MMC, so it's probably better to load only the
index, and the clip parts later on demand. So the voice file can grow as
large as you want on Ondio.
