How to Update U-Boot on Warp7 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/ (if you are in a Debian distribution then you can get it via libdfu-dev package) - libusb: http://libusb.org/ (if you are in a Debian distribution then you can get it via libusb-dev and libusb-1.0-0-dev) In U-Boot folder, build U-Boot for Warp7: $ make mrproper $ make warp7_config $ make This will generate the U-Boot binary called u-boot-dtb.imx. Put warp7 board in USB download mode: Remove the CPU board from the base board then put switch 2 in the upper position Connect a USB to serial adapter between the host PC and warp7 Connect a USB cable between the OTG warp7 port and the host PC Copy u-boot-dtb.imx to the imx_usb_loader folder. Load u-boot-dtb.imx via USB: $ sudo ./imx_usb u-boot-dtb.imx Then U-Boot should start and its messages will appear in the console program. Open a terminal program such as minicom Use the default environment variables: => env default -f -a => saveenv Run the DFU command: => dfu 0 mmc 0 Transfer u-boot-dtb.imx that will be flashed into the eMMC: $ sudo dfu-util -D u-boot-dtb.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 warp7 board. Put warp7 board into normal boot mode (put the switch 2 in the lower position) Power up the board and the new updated U-Boot should boot from eMMC
