Networking Problems Cropping Up w/ NetWiFiuSD

Rate this Message:
I've been working with my new Gumstix stack for my robot (Verdex, netWiFiuSD, Robostix) for about a month now, finally got comfortable with everything and have started running into frustrating problem after problem now. Initially I was having a lot of trouble with the I2C Timeout problem that seems to plague at least a few people, but now severe problems with the networking are coming up.
Both the WiFi and ethernet were working great for several weeks but recently the wired ethernet has been grossly dropping packets and the WiFi has me completely perplexed. I can scan for APs and such and it works normally but if I try to associate with one it doesn't work. Sometimes the ethernet connection works great and drops few packets but other times it's completely hopeless. I've tried all the normal things, changed my cable, different drops, different network, reseating all my boards, different power sources, different rootfs/kernel. I would normally attribute it to a bad board but the performance seems to change so randomly whether or not I touch any of the boards that I'm unsure of it (though that does seem to indicate thermal expansion problems to me, but I'm just a mechE). I'll try to include all the relevant info I can here: gumstix_smc91x_init: smc91x chip not found, returning -ENXIO smc91x: Unknown symbol gumstix_smc91x_load eth0: LAN9117 (rev 2) at 0xc4870000 IRQ 131 eth0: Ethernet addr: 26:9f:27:80:cd:50 Bluetooth: Core ver 2.11 NET: Registered protocol family 31 Bluetooth: HCI device and connection manager initialized Bluetooth: HCI socket layer initialized Bluetooth: L2CAP ver 2.8 Bluetooth: L2CAP socket layer initialized Bluetooth: HIDP (Human Interface Emulation) ver 1.2 usbcore: registered new interface driver usbfs usbcore: registered new interface driver hub usbcore: registered new device driver usb pxa27x-ohci pxa27x-ohci: PXA27x OHCI pxa27x-ohci pxa27x-ohci: new USB bus registered, assigned bus number 1 pxa27x-ohci pxa27x-ohci: irq 3, io mem 0x4c000000 usb usb1: configuration #1 chosen from 1 choice hub 1-0:1.0: USB hub found hub 1-0:1.0: 3 ports detected Not netCF-vx board: using newer GPIO configuration CPLD responded with: ff Bluetooth: RFCOMM socket layer initialized Bluetooth: RFCOMM TTY layer initialized Bluetooth: RFCOMM ver 1.8 root: mount: special device /dev/hda1 does not exist root: mount: special device /dev/mmcblk0p1 does not exist root: mount: special device /dev/sda1 does not exist Setting up IP spoofing protection: rp_filter.

I went out and got a uSD card so I might try continuing my work with the gumstix while the ethernet is dead, but it looks like that is broken too. Here are the errors I'm getting:

A little more futzing around and I've become even more confused about the situation. I've been trying to get a handle on the I2C communication problems with my Robostix and ended up flashing this image from Dave Hylands: http://www.davehylands.com/gumstix-wiki/vx-1574-robo/ and upon booting up my ethernet works completely perfectly. I'm also able to use my uSD card from inside uBoot without any problems which is how I've been doing all my flashing.
I flashed the newest pre-built gumstix image from the feed to make sure it wasn't a hardware thing and the same old problems came right back. I flashed one of my own custom kernels without the framebuffer enabled (for the robostix) and have the same problem. I flashed Dave's buildroot image onto it and it works perfectly. I'm not sure what I have to do to get someone interested in helping me out, I've been doing all I can. I've got an order of several more gumstix coming to try to rule out possible hardware problems (though they seem to be taking forever like the first one I got) but I'm increasingly worried that I've got a software problem I can't handle. Does anyone have some idea what could possibly be going on here? --Zack Jackowski

Hi Zack,
I recently had problems with my netmicroSD and finally figured out that I was having the problem reported earlier http://www.nabble.com/NetMicroSD-eth0-transmit-but-no-recieve...-to13461420. html#a13461420 where some SMT parts on the underside of the netmicroSD were shorting out on the metal housing of the BT module. I don't know if you have the XM4-bt, but if you do here's what I found. Using ethereal I saw continual ARP requests from the gumstix (when trying to ping) following by MAC replies from the destination host which the gumstix never seemed to receive. Also, eth0 comes up as "half-duplex" which didn't seem right. To solve this I cut a small square of paper and slide it between the boards; eth0 now comes up as "full-duplex" and the problem disappeared. The boards still touch even using the spacer kit, so some kind of insulation is needed. Anybody with a XM4-bt + netmicroSD may potentially have this problem.

Hi Shane,
You need to use a GUI based application (such as X11) to run gnome-terminal in. ~Shane On Fri, 25 Jul 2008 16:48:13 -0600 "Shane Kirkbride" <skirkbri@...> wrote: > Hi, > I am trying to optimize the kernel for my Verdex.

Thanks for tip, definitely a good piece of info, but sadly not the case for me. Even though I don't have the BT module one of the first things I did in my attempts to solve this problem was put little slips of paper between each of the boards in my stack, just one of the things I've picked up to do over the years.
