IMX6ULL EVK NAND Flash

I can't use the yocto project because I don't understand it.
I think it's too complicated.

So I used buildroot-2022.11.2 and tested SD Card boot on imx6ull evk board.

# make distclean

# make clean

# make freescale_imx6ullevk_defconfig

Now I'm trying to test my NAND boot, but I have a problem from the beginning.

Which Configs file should I use?

When testing the SD Card boot, L4.1.15_2.0.0-ga_mfg-tools.tar.gz was used.

I didn't touch the firmware part, and I used what was inside the mfgtools.

( Profiles\Linux\OS Firmware\firmware)

I changed all the binaries in the file folder.

( Profiles\Linux\OS Firmware\files\SD Card )

The mfgtool records well and the board works well.

However, I tried to boot NAND in the same way, but it doesn't work.

The binary in the firmware is put on RAM by mfgtool, but no recording operation is performed thereafter.

I was wondering how to build and record.

I'm in trouble because I don't know how to use the yocto project and the UUU tool.

I wish there was a guideline to do this simply.
