How to Update U-boot on Warp board
----------------------------------

Required software on the host PC:

- imx_usb_loader: https://github.com/boundarydevices/imx_usb_loader

- dfu-util: http://dfu-util.sourceforge.net/releases/

Build U-boot for Warp:

$ make mrproper
$ make warp_config
$ make

This will generate the U-boot binary called u-boot.imx.

Put warp board in USB download mode

Connect a USB to serial adapter between the host PC and warp

Connect a USB cable between the OTG warp port and the host PC

Open a terminal program such as minicom

Copy u-boot.imx to the imx_usb_loader folder.

Load u-boot.imx via USB:

$ sudo ./imx_usb u-boot.imx

Then U-boot should start and its messages will appear in the console program.

Use the default environment variables:

=> env default -f -a
=> saveenv

Run the DFU command:
=> dfu 0 mmc 0

Transfer u-boot.imx that will be flashed into the eMMC:

$ sudo dfu-util -D u-boot.imx -a boot

Then on the U-boot prompt the following message should be seen after a
successful upgrade:

#DOWNLOAD ... OK
Ctrl+C to exit ...

Remove power from the warp board.

Put warp board into normal boot mode

Power up the board and the new updated U-boot should boot from eMMC
