1. You generate u-boot.imx in your Linux host PC

2. Put the boot jumpers to USB download mode on your board. (If you
don't have boot jumpers, then it will automatically enter in USB
download mode if a valid boot image is not found.)

3. Transfer the u-boot.imx binary via USB cable using the imx_usb
utility running on the Linux host

sudo ./imx_usb u-boot.imx

4. Then you shouls see U-boot on the board console;

Hope this helps.
