HPCN MPC8641D Development Board

giajh01 — Fri, 14 Sep 2007 15:27:53 GMT

Hi,

I'm using a HPCN MPC8641D Dev Board for evaluation purposes and I'm trying to setup a direct ethernet connection to my development PC. When I try to ping me PC from the dev board it fails most of the time.
I've include an example session at the end of the post.

My ethernet configuration looks as follows

HPCN MPC8641D Dev Board
ipaddr=192.168.1.100
serverip=192.168.1.1
gatewayip=192.168.1.1
netmask=255.255.255.0
ethact=eTSEC1
ethaddr=00:04:9f:00:56:af
eth1addr=00:04:9f:00:56:b0
eth2addr=00:04:9f:00:56:b1
eth3addr=00:04:9f:00:56:b2

Any help/ideas/suggestions on whats going wrong would be greatly appreciated.

giajh1,

As you are having intermittent problems, your basic setup is probably OK, so here is what I'd do for your case.

First as your host is a Windows PC, if you haven't done so already, download and learn how to use the free Network Monitor tool from Microsoft. Here is the download link:

http://www.microsoft.com/downloads/details.aspx?familyid=18b1d59d-f4d8-4213-8d17-2f6dde7d7aac&displaylang=en

Running this should be able to help you narrow down the problem if it is a problem with the target board sending pings, the host responding to them or the target dropping the ping responses.

Another thing I did with my Windows PC ( I am running Vista, but XP should be the same) was for the dedicated port connected to my target, I went in to device manager and turned off and disabled all all other protocols ( examples, DHCP, DNS, IPv6, network sharing, QoS, etc. ) as one thing a Windows host will do is "look for friends" and "auto configure" when you really don't want it to.

One other thing I did notice that you had both your serverip and your gatewayip set to the same address. This combination would normally only be configured if your PC is also your router (Windows can do it, but I wouldn't recommend it). It probably shouldn't affect u-boot, but you also might try changing your gatewayip to a different address than your serverip.

Hope this helps,

P.S. It looks from your trace that your Windows PC is setup for German. I did a quick look a the Microsoft Germany site, but it only had a link to the English site, so it appears that there isn't a German Download of this program.

Hi abartky,

Thanks for the quick and helpful reply. Ironically enough it fixed itself i.e. powered everything back up Monday morning and ping, tftp etc. worked without a glitch and more importantly without any changes from my side. Sadly I'm none the wiser as to what was wrong originally. Should the problem occur again I'll be sure to try out your suggestions.

In the meantime I'll try to find the cleaning lady, as she appears to know more about this development board than I do :smileywink:

thansk again for your help
