Can't boot from the NAND FLASH on our custom imx6ul board

Hi ,

Our custom imx6ul board can't boot from the NAND Flash after we burn in the nand flash via the micro-SD.

We just chose  the Micron MT29F32G08CBADBWP MLC NAND FLASH. We had found the nand flash hardware infomation when we burn in the nand flash via micro-SD:

nand: device found, Manufacturer ID: 0x2c, Chip ID: 0x44
nand: Micron MT29F32G08CBADBWP
nand: 4096MiB, MLC, page size: 8192, OOB size: 744
gpmi-nand 1806000.gpmi-nand: Default ecc strength(52) is beyond our capability(40). Try to use maximum ecc strength controller

After burn in, we had set boot mode as below:

Boot_cfg1[0:1]  = 00 (3 row address bytes)

Boot_cfg1[2:3] = 00 (1 nand device)

Boot_cfg1[4:5] = 11 (256 pages per block)

Boot_cfg1[6] = 0

Boot_cfg1[7] = 1 (nand boot)

But we boot from NAND flash failed. There is no any boot log in cosole. Please help us for this issue.

Thanks.

Hi,

You can refer to the How-To use NAND boot on i.MX6UL EVK board thread in our community.
Have a great day,
