[U-Boot] Fw: TFTP fails when using network switch

Hi Everyone,

I am having an interesting problem with am m5282Lite Dev Kit. I had
done all of the previous development work by connection the card
directly to a spare ethernet card in my PC via a cross-over
cable. This worked just fine and the tftp download was very fast. Now
I have run a long Ethernet cable and can download the uClinux using
u-boot, but the hub is 10Mbit. I get some "bad len" errors but
eventually (seems to take a long time) the download completes and
uClinux boots. I then tried to hook up a spare 100MBit switch i had
running one Ethernet cable to the pC (tftp server) and one to the
coldfire board (now using regular network cable) but the tftp just
times out. The funny thing is i seem to be able to ping the coldfire
from the PC side but not the PC from the coldfire side. Does anyone
have an idea of what is wrong? Thanks in advance!

Alex
