I am using iMX8MM evk.

I am trying flashing Kernel image to eMMC using UUU tool.

I found mentioned UUU can download both u-boot ( aggregated with spl and other fw images ) and Kernel Image.

I tried it and bootloaders were flashed successfully but not the Kernel Image, because of its size .

This is the error I got :

sudo ./uuu -b emmc signed_flash.bin Image_pad_ivt.bin
uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.3.154-0-g47ddef5

Success 0 Failure 1

1:2 4/ 7 [image too large for partition ] FB: flash bootloader Image_pad_ivt.bin
1:3 3/ 3 [=================100%=================] SDPV: jump


is uuu -b emmc the right command to use or should I use other script rather than the "emmc" one?

I tried also other option "emmc_all" but I got same error.

My padded image with ivt is a bit larger than 24 Mbytes.


What is wrong ?Should I program to a FAT partition created by u-boot commands ? If so how can this be automated in production?
