| 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. |
