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.
