Overall steps:
- Prepare an SD card or eMMC Module as a boot disk.
- Burn Uboot firmware into EMMC.
- Flush the system image to the NVME SSD.
- Unplug the SD card and boot from NVME.
Prepare an SD card or eMMC Module as a boot disk
The firmware can be downloaded from the Armsom official website
Refer to the section on making a MicroSD boot disc to install the system on the SD card.
Burn Uboot firmware into EMMC
There is no SPI flash on the development board, and the Uboot firmware needs to be installed on the EMMC.
There are two storage paths for uboot firmware:
One is in the system image:
armsom@armsom-sige7:~$ ls /usr/lib/linux-u-boot-current-armsom-sige7/
idbloader.img rkspi_loader.img u-boot.itb
Another one is generated during the compilation of the source code:
armbian/build/output/debs/linux-u-boot
Use the dd command to flash firmware into EMMC：
dd if=./idbloader.img of=/dev/mmcblk0 seek=64 conv=notrunc status=none
dd if=./u-boot.itb of=/dev/mmcblk0 seek=16384 conv=notrunc status=none
Flush the system image to the NVME SSD
Insert the NVME SSD into the board and verify that the NVME is recognized by the system
armsom@armsom-sige7:~$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
mmcblk0 179:0 0 115.3G 0 disk
mmcblk0boot0 179:32 0 4M 1 disk
mmcblk0boot1 179:64 0 4M 1 disk
mmcblk1 179:96 0 29.7G 0 disk
└─mmcblk1p1 179:97 0 29.4G 0 part /var/log.hdd
/
zram0 251:0 0 15.5G 0 disk [SWAP]
zram1 251:1 0 50M 0 disk /var/log
zram2 251:2 0 0B 0 disk
nvme0n1 259:0 0 13.4G 0 disk
└─nvme0n1p1 259:1 0 13.3G 0 part
As shown above the system already recognizes the NVME SSD as nvme0n1 (in Linux NVMe devices are usually recognized as nvmeXnY)
Copy the system image you want to run into the development board
PC Host: scp /path/to/img armsom@boardIP:/tmp
Then dd the system image into NVME on the board .
armsom@armsom-sige7:/tmp$sudo dd if=./Armbian_community_24.11.0-trunk.351_Armsom-sige7_noble_current_6.11.5_gnome-kisak_desktop.img of=/dev/nvme0n1 bs=1M status=progress
Unplug the SD card and boot from NVME
After removing the SD card, power up the system using the 12V/2A PD power adapter, then the system starts booting from NVME and HDMI displays the desktop
