imx8mn boot from 8bit NAND, 256 pages per block

[tvothang]

Hi,

We are designing a custom board, based on imx8mnlpddr4evk.
But instead of booting from the NOR flash, we will be booting from the NAND flash.
NAND flash is MT29F16G08CBACAWP: 8bit NAND, 256 pages per block.

In imx8mnlpddr4.conf, we have UBOOT_CONFIG[sd] and UBOOT_CONFIG[fspi], but no UBOOT_CONFIG[nand].
How can we generate the uboot defconfig for NAND?
Does IMXBOOT_TARGETS need to be modified?

How can I generate the bootloader for NAND?

Thanks,
Thanh

Hi Thanh

for  nand "UBOOT_CONFIG" one can look at

https://community.nxp.com/t5/i-MX-Processors/Overwrite-UBOOT-CONFIG-on-imx6ullevk/m-p/925724

for MT29F16G08CBACAWP, it is MLC, one can look at
