Hello,
I am trying to boot a custom linux image with tftpboot with uboot, because I have multiple boards connected to my network.
I am able to ping my tftp server, but I don't know where to load the kernel.
Can someone help me with the setup please?
Thank you.

Thank you for your prompt response. This worked for me: - unplug the board - keep pressing the boot button - replug the board ``` Bus 003 Device 074: ID 2207:110c Fuzhou Rockchip Electronics Company ./upgrade_tool ld Using /luckfox-pico/tools/linux/Linux_Upgrade_Tool/config.ini List of rockusb conne...
