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 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
