Upgrade went wrong - now I cant even connect with serial cable

  • I tried to upgrade my Pfsense appliance but after flashing the firmware the device couldnt be seen on the network again.

    I attached a null modem cable to try and see what's wrong with it, but the output of the screen is barely intelligible. I tried connecting via a linux box using screen like this:

    screen /dev/ttyS0 9600,cs8,-parenb,-cstopb,-hupcl

    I can barely make out that the device is booting, the last thing to be seen on the screen is this

    Here is the output I do see on the screen

    I've tried 115200 baud aswell as 38400 neither seem to work! Is this some emulation problem?</cf></amd></sb></ata></a<br></amd></isa></vi></via></mii></ge>

  • Looks like an ALIX, which should be 38400 by default. Though the baud rate you were using where you got that text has to be correct, otherwise you wouldn't see anything legible like that. The weirdness of the display makes me wonder if it's a USB to serial adapter issue (hardware or driver).

  • After Googling ALIX, it certainly does look like one.  The connection is from a serial port on a linux desktop to the serial port on the appliance via null modem cable, no USB involved at all. I had slightly better luck using minicom instead, but 9600 baud is the only speed that will work sort of. It doesnt appear to be taking any input.

    What can I do now? Can I flash the appliance again? I've effectively bricked the device, unless I can find a way forward

  • Banned

    Sure, just remove the CF card and reinstall.


  • Fresh install 2.2 with PuTTY. Alix HW output reads with 9600 or 38400. pfSense 1st boot & base setup output works with 115200. Until you've set 38400 in webgui.
