I've used the pre-installed u-boot loader (I think of the SD-Card, not
eMMC) delivered together with the board. This is the u-boot greeting:
U-Boot 2009.08 (Apr 29 2013 - 18:01:51)
I use the following script procedure, first the commands of the
SD-card's boot environment:
dhcp; source 0x10800000
The DHCP server delivers another script:
setenv serverip X.X.X.X
tftp 0x30000000 /var/lib/tftpboot/uImage
bootm 0x30000000
The last commands load the uImage file from my machine and runs it.
Best regards
Stefan
