wget or scp command
$ flex-installer -b bootpartition_LS_arm64_lts_<version>.tgz -r rootfs_ubuntu_bionic_LS_arm64.tgz -
d /dev/sdX
Step 3: Power on or reboot the target board after finishing the distro installation, the system will enter boot loader (U-Boot) and
automatically scan boot configuration script from the attached SD/USB/SATA disk and boot the target LS1028A BSP distro if found,
otherwise it falls back to boot from Flexspi-NOR flash with tiny ramdisk distro.
How to program firmware to SD/Flexspi-NOR flash media

For SD card (on all platforms):
1. Download the prebuilt image (take LS1028ARDB for example):
— Option 1: Load the prebuilt image from SD card in U-Boot:
=> load mmc 0:2 a0000000 firmware_ls1028ardb_uboot_sdboot.img 
— Option 2: Download the prebuilt image using the wget command:
$ wget https://www.nxp.com/lgfiles/sdk/ls1028a_bsp_03/
firmware_ls1028ardb_uboot_sdboot.img
— Option 3: To locally generate firmware_ls1028ardb_uboot_sdboot.img, run the command as below:
$ flex-builder -i mkfw -m ls1028ardb -b sd
2. Program firmware_<machine>_uboot_sdboot.img to SD card:
—
Under U-Boot:
=> load mmc 0:2 a0000000 firmware_ls1028ardb_uboot_sdboot.img 
=> mmc write a0000000 8 1fff8 (same on all platforms) 
=> qixis_reset sd
—
Under Linux:
$ flex-installer -f firmware_ls1028ardb_uboot_sdboot.img -d /dev/mmcblk0
•
For Flexspi-NOR flash:
— On LS1028ARDB:
1. Download the image using the following options:
◦ Option 1: Load prebuilt image from SD card.
=> load mmc 0:2 a0000000 firmware_ls1028ardb_uboot_xspiboot.img
◦ Option 2: Download the prebuilt image using the wget command.
$ wget https://www.nxp.com/lgfiles/sdk/ls1028a_bsp_03/
firmware_ls1028ardb_uboot_xspiboot.img
◦ Option 3: To locally generate firmware_ls1028ardb_uboot_xspiboot.img, run the command as below:
$ flex-builder -i mkfw -m ls1028ardb -b xspi
