Hi,
I was wondering what it takes to connect the ethernet port of a beagle-
xm directly (without a switch) to a PC and use it from u-boot.
So far I tried direct connections with straight and crossover cables
without success.
As soon as I put a switch in between everything works as expected.
Here is what I do with U-Boot 2011.12 mainline with a switch attached:
OMAP3 beagleboard.org # dcache off
Data (writethrough) Cache is OFF
OMAP3 beagleboard.org # setenv usbethaddr 0:0:1:2:3:4
OMAP3 beagleboard.org # setenv ipaddr 192.168.66.135; setenv serverip
192.168.66.35; setenv netmask 255.255.255.0; usb start
(Re)start USB...
