Ah, in /boot/loader.conf, not /etc/sysctl.conf. Thanks! That fixed the problem.

It's a Kingston 1GB 50x 'elite pro' The problem is that the CF card reports DMA capability but on older 4801's the CF card is not wired for that. FreeBSD cannot see the missing wires, and things get stuck. You can set hw.ata.ata_dma=0 in the loader to tell the disk driver to not attempt DMA. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [EMAIL PROTECTED] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. ___ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech

I can't boot the Soekris box, so I can't run atacontrol there. How do I make the appropriate settings on the other box (the one that has the CF on a USB reader) so that they live through the bootup on the Soekris box? --Paul Hoffman ___ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech
Re: [Soekris] net4501 I/O Port
Hi, Many thanks for your advices :) I've built a kernel, using an AMD Elan subarch, just to try... I've bought my soekris less than two weeks ago... I've built a kernel like that to see if there was optimization in linux kernel. I will compile a new kernel in a x86 subarch, you are right, it will make me easier compile kernel module, or userland code ;) Best regards, Serge.

What seems to "fix" it is a packet going on the outbound interface will 'unwedge' it so that the box can received packets once again. In the logs, a vr0: Using force reset command. will appear. It also seems to happen more frequently on vr0 than the other nics. Not sure if its an interrupt issue ? The newer version of the driver soon to go into HEAD seems to reduce the amount of "force reset command" that I see. I havent yet seen a situation where the interface stops receiving packets with the new driver. But then again, I cant make this situation appear on demand so I dont know if the problem is gone, or just less visible. ---Mike >___ >Soekris-tech mailing list >Soekris-tech@lists.soekris.com >http://lists.soekris.com/mailman/listinfo/soekris-tech ___ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech
[Soekris] net5501 vr(4) repeated unplug/replug -> port stops working
I've seen some problems with the onboard NICs on net5501, where if the device connected is unplugged and replugged, the interface has link, is able to transmit packets, but is unable to receive packets (nothing shown in tcpdump on the interface). Bringing the interface down and back up fixes it. Has anyone noticed this on OS other than OpenBSD? ___ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech

I really don't understand the problem: - The net4501 is just an x86 PC. It runs standard x86 code. - You can boot vmware using the same image that you use to boot the net4501. - You can build the gpio-controlling binary on *any* x86 platform. If you are building kernel modules which need to be optimised for some particular quirk or extra instruction available on the SC520 CPU then maybe I'd understand, but you really don't need to be doing this. I run OpenWrt on Soekris. I just build it for x86. Regards, Brian. ___ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech

The net4501 manual tells you how the pins are brought out, and this is on the Soekris website. Google for the SC520 data sheet for programming information.

Re: [Soekris] net4501 I/O Port
Thanks for your response. that link was already in my bookmarks :) I need to install another new small linux using the AMD Elan subarch to be able to compile this code and run it. I was not able to find any documentation about the I/O ports of this board (nothing on soekris website, nothing on AMD website...) Did you find something interesting ? Thanks for your help.
