Flash Filesystem and the Edge SD socket
Hi all !
With the arrival of the Flash Filesystem, is there any sense to look at moving the Edge on-board SD card onto it's own group of pins, so that files could potentially read/write simultaneously between the devices ? This might as well include hooking in all DAT pins, even if the extra (4-bit) 2 might not be used so often. (Though it might be nice to keep the DAT pin order consecutive... so that leads to the next question...)
Is there any collective preference of which IO pins an on-board SD card might consume? And should the extra 2 DAT pins share with the on-board LEDs if the DAT-to-SmartPin order need not be strict?
And if all that happened, would having a power-cycle signal still be necessary- and if so, then which would be the preferred IO pin for that function ?
Note: I'd expect with such a change we'd want to ensure the DipSwitch settings still allow the ability to boot either from SD or Flash. (Don't think about that for now).
Note2: Maybe a power-cycle (or power-down) could be accomplished by holding the SD card pins in a certain state, to save having an additional pin for that function. Or wire in the card detect pin to an IO, and then use that as a power-down function when asserted low, or as an input to detect the card.
