Ставьте любую версии 4.5. Хотя, может и 5.0 подойдет.
На плате есть распайка под память в корпусе TSOP48. Можно ли впаять НАНД память в таком же корпусе?
Для работы с НАНД в прошивке должна быть ее поддержка, а если ее нету то и работать не будет.
Нарыл немного инфы по FORESEE NCEFAT28-08G:
FORESEE NCEFAT28-08G – NAND or eMMC? Discover here the true about this efSD memory

FORESEE NCEFAT28-08G
I have read some comments about Foresee NCEFAT28-08G memory. Some said it is a NAND Flash, others said it is an eMMC memory. None of them are true (or not at all).
I just got NCEFAT28-08G Datasheet and I could confirm that this is an hybrid memory called efSD memory with eMMC 4.51 specification compatibility.
FORESEE efSD is an embedded storage solution designed in the BGA package. The FORESEE efSD consists of NAND flash and eMMC controller. The controller could manage the interface protocols, wear-leveling, bad block management and ECC. FORESEE efSD has high performance at a competitive cost, high quality and low power consumption, and efSD is compatible with JEDEC standard eMMC 4.51 specifications.
