Hello All,


I am new to this topic of bootloader and kernal image loading.

I am trying to use uuu tool and it only executes the first command of loading the bootloader. It stucks there and could not able to proceed to the next command.

My script contains,


uuu_version 1.2.39

# Please replace below item with actual name
# @_flash_fw.bin | boot loader firmware, for i.MX8QM/QX, it's different from _flash.bin, for all other platforms, it's same as _flash.bin
# @_flash.bin | boot loader file burn to NAND
# @_Image | linux kernel image, zImage for arm32, Image for arm64
# @_board.dtb | board dtb file
# @_initramfs.cpio.gz.uboot | initramfs
# @_tee | optee image
# @_rootfs.tar.bz2 | rootfs

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

FB: ucmd setenv fastboot_buffer ${loadaddr}
FB: download -f zImage
FB: ucmd setenv fastboot_buffer ${fdt_addr}
FB: download -f imx6ull-14x14-evk-gpmi-weim.dtb
FB: ucmd setenv fastboot_buffer ${initrd_addr}
FB: download -f fsl-image-mfgtool-initramfs-imx_mfgtools.cpio.gz.u-boot
FB: ucmd setenv bootargs ${bootargs} ${mtdparts}
#FB: ucmd setenv bootargs console=ttymxc3,115200 ${mtdparts}
FB: acmd ${kboot} ${loadaddr} ${initrd_addr} ${fdt_addr}


The Output is:
