How to set NAND_READ_CMD_CODE1/2 for NAND Boot

MartinHo — Thu, 24 May 2018 14:05:45 GMT

Hi I'm working on the fuse configuration to boot from my raw NAND (MT29F4G08ABAEA), but I'm confused if I have to set the two NAND_READ_CMD_CODE fields. Do I need to burn this fuses and if Yes to what value (Read Page --> 0x00 and 0x30 ?).

I have already set the following fuses:

0x05 (b00,w05) 0x0450 OCOTP_CFG4 = 0x00001280

CFG1 = NAND, raw, 1 Device, 3 row address bytes (nedds to be 5 row?)

CFG2 = Block has 64 Pages, BOOT_SEARCH_CONT = 4

CFG3 = not used

CFG4 = not used

0x06 (b00,w06) 0x0460 OCOTP_CFG5 = 0x00000010

(BT_FUSE_SEL = 1)

Con You please help me to set

0x07 (b00,w07) 0x0470 OCOTP_CFG6

thanks

Martin

Hi Martin

nand boot will work fine without changing default NAND_READ_CMD_CODE fields.

They can be used for some non-standard cases.
