The next step is to load the final U-Boot version (normally named 'u-boot.bin'). This time the transfer
starts automatically. The result looks as follows:
Now you can start the final U-Boot version with ' go 81000000 '.
5.2 Ethernet Bootloader
For download over Ethernet you need a TFTP (Trivial File Transfer Protocol) server with DHCP ability.
Note: Use only the first Ethernet port (J1600).
Some preference changes are necessary:
This method strictly needs a jumper on pin header J1101 (see User's Guide chapter 'Serial
Console').
Rename the U-Boot-MIN file named 'u-boot.min.eth' in 'MLO'.
Copy 'MLO' and u-boot.bin' into the same directory.
The ROM code tries first to load the U-Boot-MIN part over the serial interface but this approach fails.
Afterwards the ROM code etablish the Ethernet connection and loads MLO and subsequently the real U-
Boot version. As a result of the serial interface timeout the network connection is rather slowly.
