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?

Hi Fabio and Marek
Trying to understand the reason why I can boot using imx_usb loader and not the uuu tool
If I do:
./imx_usb SPL ./imx_usb u-boot-dtb.img
It works

If I tried with the combined image using uuu it does not work like that.

Any idea?
