The NAND-Flash used on ICnova SAM9G45 OEM and ICnova SAM9G45 SODIMM is the same and connected nearly equally. The following parameters are met for this device:
Typ | NAND02GW3B2 |
VCC | 3.3V |
Buswidth | 8bit |
Startaddress | 0x40000000 |
ALE-AddressBit | 21 (0x40200000) |
CLE-AddressBit | 22 (0x40400000) |
CE on GPIO | PortC Pin8 on OEM, Pin 14 on SO-DIMM |
RnB on GPIO | PortC Pin11 on OEM, Pin 8 on SO-DIMM |
To acccess the NAND-Device using a custom bootloader, the AT91SAM9G45 EBI Interface must be configured accordingly and the EBI_CS3A Bit in the EBICSA Register must be set to activate NAND-Logic.
