Update SPI Flash Firmware

Update the SPI Flash firmware of Radxa AICore AX-M1 from the host board.

Prerequisites

• This operation writes to SPI Flash. Make sure the power supply is stable and do not power off during the update.
• The following commands are executed on the host board (Host).

Install software

Go to the Downloads page to download the required software packages, and place them in the same directory.

Host

sudo dpkg -i axclhost-firmware_3.6.5-1_all.deb
sudo dpkg -i task-axclhost_3.6.5-1_all.deb
sudo dpkg -i axclhost-dkms_3.6.5-1_all.deb
sudo systemctl restart systemd-modules-load

Detect the device

Verify that the host recognizes the SPI Flash device node of Radxa AICore AX-M1.

Host

axcl-smi sh "ls /dev/mtd0"

If the output shows that /dev/mtd0 exists, the device node is present.

Update firmware

Go to the Downloads page to download the SPI Flash firmware file, and make sure the firmware filename matches the command arguments.

Host

axcl_spl_update -i spl_AX650_card_signed.bin -d 0

-d 0 selects the device with index 0.

Post-update verification

After the update is completed, it is recommended to reboot the host board and check that the device node is still present.
