TIP:
address. This will cause trouble if there are two or more boards in the same
local network. Assigning a custom MAC address is easy. When U-Boot is
starting press a key to enter the U-Boot shell. There set the Ethernet
address:
And then save the settings to dataflash:
Another option is to open the programming script
and set the Ethernet address there. Search for "ethaddr" to find where to
edit. Then reflash the board memories (see the RESTORING THE
INSTALLATION section).
TIP:
via TFTP. You need to set the board's IP address, the TFTP server IP
address and a few more U-Boot environment variables. So stop U-Boot by
pressing ENTER during the countdown after reset, and type the following
lines in the U-Boot prompt:
The above example assumes you board gets IP 192.168.0.239, your TFTP
server has IP 192.168.0.225, and the kernel image filename is "uImage".
CAVEAT:
touchscreen utilities from operating on a 24bit framebuffer. This is fixed in
the provided root filesystem images. In case you're building your own root
filesystem, here is a patch that fixes the problem:
