OMAP-L138: L138 bootloader supported NAND device

Tony Tang

Part Number: OMAP-L138

For device ID is not in the supported list, bootloader will ready 4th ID byte. 

Does it only support bit 6 with 0 (8bit device)? how about bit 6=1 device?

The LCDK use MT29F4G16ABA, its device ID is 0xCC, not in the support list. and 4th ID is 0x56, which bit 6 is 1, so I think the bootloader app notes Table 13 missed something.

    Tony,

    That is correct. The 6th bit is used for differentiating between 8bit and 16 bit NAND devices.

    0 corresponds to 8bit  NAND

    1 corresponds to 16bit NAND

    Here is the ROM code that shows this configuration:

    I will file an lit bug for the document to add the 16 bit NAND buswidth reference to the document.

    Regards,

    Rahul
