Enter U-Boot on cubox-m

I was able to build my own image based on GitHub - SolidRun/meta-solidrun-arm-imx8. With cubox-i device I was able to enter u-boot with any keypress during startup, but on cubox-m I am not able to do this.

I need to set up constant MAC address in u-boot. How to do this? Right now every restart generates random MAC address and new IP address from DHCP.

For the keypress at start issue. Make sure you don’t have hardware flow control enabled in your terminal emulator settings.

For the MAC address, there will be a new kirkstone meta-layer update pushed this week that will fix this.
