Update from original Marvell U-Boot to mainline U-Boot: ------------------------------------------------------- Generate the U-Boot image with these commands: $ make helios4_defconfig $ make The resulting image including the SPL binary with the full DDR setup is "u-boot-spl.kwb". Now all you need to do is copy this image on a SD card. For example with this command: $ sudo dd if=u-boot-spl.kwb of=/dev/sdX bs=512 seek=1 Please use the correct device node for your setup instead of "/dev/sdX" here! Boot selection: --------------- Before powering up the board, boot selection should be done via the SW1 dip switch (0: OFF, 1: ON): - SPI: 00010 - SD/eMMC: 00111 - SATA1: 11100 - UART: 11110 Boot from UART: --------------- Connect the on-board micro-USB (CF Pro: CON11, CF Base: CON5) to your host. Set the SW1 DIP switches to UART boot (see above). Run the following command to initiate U-Boot download: ./tools/kwboot -p -b u-boot-spl.kwb /dev/ttyUSBX Use the correct UART device node for /dev/ttyUSBX. When download finishes start your favorite terminal emulator on /dev/ttyUSBX.
