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

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.

What am I doing wrong with the .wic download?
What am I supposed to do in order to flash the .wic file into QSPI-flash?
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

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.

Regards

I followed this document and it works. https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/all-bootloader-device-tree-Linux-kernel-...
