Flashing from NOR FLASH in i.MX-93

[Robbi]

Hi Team,

                  I had tried successfully booting from eMMC and SD, now I' trying to boot from NOR-FLASH. Please guide me the approach. which commands need to be used to copy the files from SD-card to QSPI and any changes need to be done like offset. Please do the needful.

Thanks

In your Yocto build environment, please add the following line in build-wayland-imx9/conf/local.conf

UBOOT_CONFIG = "fspi"

Then buil FSPI NOR flash image with the following command.

$  bitbake imx-boot

You will get imx-boot-imx93-14x14-lpddr4x-evk-fspi.bin-flash_singleboot_flexspi in folder build-wayland-imx9/tmp/deploy/images/imx93-14x14-lpddr4x-evk.

Then deploy this image from SD u-boot with the following command.

=>tftp 0x80000000 imx-boot-imx93-14x14-lpddr4x-evk-fspi.bin-flash_singleboot_flexspi

(If copy from SD card fatload mmc 0:1 0x80000000 imx-boot-imx93-14x14-lpddr4x-evk-fspi.bin-flash_singleboot_flexspi）

=> sf probe 0:0

=> sf erase 0 +$filesize

=> sf write 0x80000000 0 $filesize

Then configure the switch setting to boot from QSPI NOR flash.
