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
