uuu using u-boot-with-spl.imx

[Michael Nazzareno Trimarchi]

Hi Fabio

I have managed to boot with this lts

uuu_version 1.2.39

# @_flash.bin            | bootloader
# @_uboot.bin            | uboot.dtb
# @_image [_flash.bin]   | image burn to nand, default is the same as bootloader

# This command will be run when i.MX6/7 i.MX8MM, i.MX8MQ
SDP: boot -f _flash.bin

# These commands will be run when use SPL and will be skipped if no spl
# if (SPL support SDPV)
# {
SDPV: delay 1000
SDPV: write -f _uboot.bin
SDPV: jump
# }

FB: ucmd setenv fastboot_buffer ${loadaddr}
FB: download -f _image
FB: ucmd if test -z "$fastboot_bytes"; then setenv fastboot_bytes $filesize; fi
# Burn image to nandfit partition if needed
FB: ucmd if env exists nandfit_part; then nand erase.part nandfit;
nand write ${fastboot_buffer} nandfit ${fastboot_bytes}; else true;
fi;
FB: ucmd nandbcb init ${fastboot_buffer} nandboot ${fastboot_bytes}
FB: Done

and using
sudo uuu -b nand_spl.lst SPL u-boot-dtb.img u-boot-with-spl.imx

I need to arrange the UBOOT_OFFS and OFFS_REDUNT position to take into
account the padding of 0x11000 and the two copies of nandbcb tools.

Do you know how others are flashing nand on the imx6 family?
