Installation Steps

The following steps apply to flashing the image to the first board in the cluster

Flashing Image

Use gzip to decompress the image. Use dd to flash the image to the microSD card.

gzip -d /path/to/openwrt.img.xz
sudo dd if=/path/to/openwrt.img of=/dev/your_device bs=1M status=progress

Flashing Bootloader

Use the u-boot downloaded above for this step.

sudo ./fastboot flash ram ./path/to/your/lpi4a-$(ram_size)-u-boot-with-spl.bin
sudo ./fastboot reboot
sleep 10
sudo ./fastboot flash uboot ./path/to/your/lpi4a-$(ram_size)-u-boot-with-spl.bin

Logging into the System

Login to the system via SOL (Serial Over LAN).

Default BMC username: root

Default BMC password: 0penBmc Note that it is 0 not O

Connect using ssh -p 2301 root@lichee-rv.local

Upon initial boot, automatically logged in as root.

Common Issues

If USB is not working, it may be due to Linux device tree require patching. Download patch here

Expected Results

The system should start up correctly and allow login via SOL (Serial Over LAN).

Actual Results

The system booted successfully and login via SOL (Serial Over LAN) was possible.
