Examples for k2hk, for k2e and k2l just replace k2hk prefix accordingly.
Don't forget to add ARCH=arm and CROSS_COMPILE.

+Open BMC and regular UART terminals.

+1. On the regular UART port start xmodem transfer of the u-boot.bin
+2. Using BMC terminal set the ARM-UART bootmode and reboot the EVM

+3. When xmodem is complete you should see the u-boot starts on the UART port
