Luckfox Forums

I am trying to use the upgrade tool but I am getting the following message when I type the following command sudo upgrade_tool uf upgrade.img

Loading firmware...
Loading firmware failed!

I am using Ubuntu 22.04. I have followed the instructions on the website. My LuckFox Pico has a MicroSD in it and is connected to the computer through USB. How can I fix this problem?

Hello, the upgrade_tool only supports flashing images to SPI NAND and eMMC. If you are using the Luckfox Pico (which does not have SPI NAND), the flashing will not be successful. You need to use a card reader to flash the image to the SD card first, then insert it back into the Luckfox Pico and power it on to boot.
