SBC2 Ethernet issue

Postby berkinet » Thu Mar 17, 2016 12:22 pm

I have had an ongoing problem, like over a year, with an SBC2 (details below). This problem only occurs on this particular SBC2 (I have 3 others). At seemingly random times the Ethernet port freezes. That is, it stops communicating and seems to power down - the switch the SBC is connected to shows the port as disconnected. Simply unplugging the RJ45 from either the SBC2 or the switch resolves the problem - until it occurs again. I have tried switching ports on the switch, and changing cables, but the problem happens of every port I have tried. (FWIW, this is a high-quality 24port HP switch).

I already doing a reboot at 03:00 in the cron. However, I usually notice this problem in the morning, so, it is possible the port never actually starts up after the reboot. As noted above, this only happens occasionally, usually 2 or 3 time a month.

Any ideas on this problem?

Richard

You could try a system software update from here: http://www.phidgets.com/docs/OS_-_Phidg ... _Downloads

This would blow away your entire userspace, and upgrades the kernel and system to Debian 7.8. There were some ethernet fixes in the 1.1.1 release, I'm not sure if you are having that same issue.

Thanks Patrick. Since the only data I have on the SBC is my one-line crontab entry, I will give the update a try.

Patrick:

The Phidgets OS web page states:
You will need to have an update file on a USB key inserted into the SBC, of type:
    UBI Image (system_ubi.img), or
    Kernel image (uImage), or
    Phidget Upgrade package containing both UBI and Kernel images (phidgetsbc*.bin)
These are either obtained from the Phidgets website,


But, I can't seem to find the "Phidget Upgrade Package" anywhere?
