Test Environment

System Information

System version: v2.2-minimal
Download Links: https://archive.spacemit.com/image/k1/version/bianbu/v2.2/
Reference Installation Document: https://wiki.sipeed.com/hardware/en/lichee/K1/lpi3a/1_intro.html

Hardware Information

Lichee Pi 3A
Power Adapter
A USB to UART Debugger
A microSD Card (If flash to SD card)
A type-C cable for fastboot flash

Installation Steps

Flashing the Image (SD Card)

Please make sure to choose the file ending with .img.zip After downloading and extracting the image, use dd to flash the image to the microSD card.

unzip bianbu-24.04-minimal-k1-v2.2-release-20250430181626.img.zip
sudo dd if=/path/to/bianbu-24.04-minimal-k1-v2.2-release-20250430181626.img of=/dev/your-device bs=1M status=progress

Flashing the Image (eMMC)

Please make sure to choose the file ending without img After downloading and extracting the image, use fastboot to flash the image to the eMMC.

unzip bianbu-24.04-minimal-k1-v2.2-release-20250430181626.zip

Hold the BOOT button while powering on/RST, to enter the fastboot mode. You shall see the dfu-device in your system:

❯ sudo fastboot devices
dfu-device       DFU download

sudo fastboot stage factory/FSBL.bin
sudo fastboot continue
# Wait for 1 sec
sudo fastboot stage u-boot.itb
sudo fastboot continue
# Wait for 1 sec
sudo fastboot flash gpt partition_universal.json
sudo fastboot flash bootinfo factory/bootinfo_emmc.bin
sudo fastboot flash fsbl factory/FSBL.bin
sudo fastboot flash env env.bin
sudo fastboot flash opensbi fw_dynamic.itb
sudo fastboot flash uboot u-boot.itb
sudo fastboot flash bootfs bootfs.ext4
sudo fastboot flash rootfs rootfs.ext4

Logging into the System

Logging into the system via the serial port.

Default Username: root Default Password: bianbu

Expected Results

The system should boot normally and allow login via the onboard serial port.

Actual Results

A Kernel Panic occurred during the boot process. See the boot log below for details.

Boot Log

A KP occurred during the boot process, in spacemit_snd_sspa_pdev_probe.
