CONFIG_SECURE_BOOT is too generic and forbids to use it for cross architecture purposes. If Secure Boot is required for imx, this means to enable and use the HAB processor in the soc. Signed-off-by: Stefano Babic <sbabic@denx.de> |

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
