IMX8MN Boot From NOR Flash

Hi Team,

We are using IMX8MNano processor with wind bond NOR Flash (W25Q01JV ). We are trying to use NOR Flash as boot device.

we built imx-boot-imx8mn-ddr4-evk-fspi.bin-flash_ddr4_evk_flexspi using Yocto.

I copied this file in NOR Flash and changed switch settings.

mtdinfo /dev/mtd0
mtd0
Name: u-boot
Type: nor
Erase lock size: 65536 bytes, 64.0 KiB
Amount of erase blocks: 32 (2097152 bytes, 2.0 MiB)
Minimum input/output unit size: 1 byte
Sub-page size: 1 byte
Character device major/minor: 90:0
Bad blocks are allowed: false
Device is writable: true

flash_erase /dev/mtd0 0x0 32
flashcp imx-boot-phyboard-polis-imx8mm-5-fspi.bin-flash_evk_flexspi /dev/mtd0

We are not seeing any log over UART Console.

Could you please guide us for this issue.

Regards

Ramji Mishra

Are you using NXP reference board or the board you designed yourself? Which version BSP are you using?
