7. Make sure the DIP switch settings on the board enable booting from FlexSPI NOR (or eMMC / SD card). (Refer to “On-
board switch options” in the preceding section for switch settings.)
8. Power-on the board and stop autoboot to enter the U-Boot prompt.
9. Program/update the composite firmware to FlexSPI NOR flash (or eMMC / SD card) as described below.
Note: <filename> in below steps refers to
firmware_ls1028ardb_uboot_xspiboot.img
for FlexSPI NOR flash boot source,
firmware_ls1028ardb_uboot_sdboot.img
for SD card, and
firmware_ls1028ardb_uboot_emmcboot.img
for eMMC as
boot source.
• Load firmware image from storage media.
Storage media
Command in U-Boot
USB
=> usb start
=> load usb 0:2 a0000000 <filename>
SATA
=> load scsi 0:2 a0000000 <filename>
SD
=> load mmc 0:2 a0000000 <filename>
eMMC
=> load mmc 1:2 a0000000 <filename>
• If FlexSPI NOR flash is to be used as boot source execute the commands below to program the FlexSPI NOR flash.
=> sf probe 0:0; sf erase 0 +$filesize; sf write a0000000 0 $filesize
=> qixis_reset
• If SD card is to be used as boot source execute the commands below to program the SD card.
=> mmc rescan; mmc dev 0; mmc write a0000000 8 0x25000
=> qixis_reset sd
• If eMMC is to be used as boot source execute the commands below to program the onboard eMMC.
=> mmc dev 1; mmc write a0000000 8 0x25000
where, 0x25000 is number of blocks (max) on eMMC that are required to write the eMMC composite firmware. Each
block is 512 bytes size.
Reboot with eMMC as boot source.
=> qixis_reset emmc
10. The system will automatically boot up BSP Ubuntu distro available from the removable storage device.
3.1.4.3 Option 2 - Deploy BSP images directly to the storage device on
a board
If the user does not have a local Linux host machine that can connect to a removable media, and/or the user does not have local
access to a reference board, the user can directly deploy BSP images to the storage device on a reference board. The reference
board may be accessed by the user remotely. For this option, a network connection to the reference board is required.
