Just a thought, but if internal storage is an issue for whatever reason, how about 2 external slots? One could be a boot slot holding a smaller, less expensive card containing the rockbox firmware and such and the other, non-bootable slot could be for the larger storage card. The advantage to this would be if the memory chip goes bad the end user can easily change it out himself. Another advantage, of course, would be ease of upgrade for the end user as external memory cards continue to increase in capacity and decrease in price. Thirdly, twice the slots means twice the potential memory capacity.
That's sort of where I was going. However I'd keep the firmware SD internal as a microSD card. Doing so removes confusion over which is which albeit at the compromise of a second user accessible slot. microSD has become quite cheap and a microSD socket will add less than US$1 to the BOM cost. The PCB footprint even including mounted card isn't much greater than a 56 pin TSSOP flash part yet provides the trivial upgrade/replacement option as above. -john -- [email protected]
