U-Boot> usb start U-Boot> usb tree U-Boot> setenv boot_targets usb0 mmc0 pxe dhcp ---> here I preserved priority to usb0 before mmc0 (for testing U-Boot capacity to select the right one - mmc, here second place) U-Boot> saveenv U-Boot> boot OBSD> set tty fb0 OBSD> boot ---> here I had to press RET twice or more for boot to work.
