How to load Linux Image into Flash NOR QSPI using custom board based on iMX93

[Bob_NXP_user]

Hello everyone,

I'm tryng to flash into my custom iMX93 board with UUU the .wic. I'm using this built-in command:

uuu.exe -b qspi core-image-minimal-imx93-11x11-lpddr4x-evk.rootfs-20250328061745.wic

But it doesn't work.

The only thing that works is the bootloader. Indeed, when I use the following command:

uuu.exe -b qspi imx-boot-imx93-11x11-lpddr4x-evk-sd.bin-flash_singleboot

the bootloader starts, even if I reset the board with the boot mode configuration "FlexSPI Serial NOR", so I think it is correctly flashed into memory.

1. What am I doing wrong with the .wic download?
2. What am I supposed to do in order to flash the .wic file into QSPI-flash?
3. Do I need to change something into the source files of the bootloader or it should be working as it comes from the nxp site?

Thanks in advance,

Best regards,

Bob

Hello,

• The following command burns boot image into FlexSPI NAND:

uuu -b spi_nand <nand_uuu_fw> <bootloader>

• To generate boot image for FlexSPI NAND boot on i.MX 93, run the following command:

make SOC=iMX93 flash_singleboot_spinand

• Note: Two binaries are generated:
  • flash.bin is the boot image burned into the SPI NAND.
  • flash_fw.bin is the NAND UUU FW image used by the UUU tool.
