NAND Flash
Nand Flash Read
nand read <SDRAM address> <NAND Flash address> <Bytes>
Example: nand read 80000000 400000 b40000
Description: Copies 11,25MByte from NAND Flash address 0x40_0000 to SDRAM address 0x8000_0000
Nand Flash Erase
nand erase <Block base address> <Bytes>
Example: nand erase 400000 40000
Description: Deletes NAND Flash content from address 0x40_0000 to 0x43_FFFF
Note: The Bytes information needs to be block size aligned!
Nand Flash Write
nand write <SDRAM address> <NAND Flash address> <Bytes>
Example: nand write 80000000 400000 b40000
Description: Cpoies 11,25MByte from SDRAM address 0x8000_0000 to NAND Flash address 0x40_0000
Note: The Bytes information needs to be page size aligned!
