APU : cannot install Pfsense…

  • Hi all,

    I've just purchased a PC Engines APU 4c and trying to install pfsense, but without success…

    I've prepared my USB stick with  pfSense-memstick-serial-2.1.3-RELEASE-amd64 img file, with Win32DiskImager.

    Trying to boot the APU with the USB Stick, but boot stops at this point :

    Booting from Hard Disk...
    Booting from 0000:7c00

    nothing else ...

    Any ideas?

    Thank you,

  • Hi Thomas.
    I am running pfSENSE from APU1C4.
    I managed to run in 2 ways:
    1. pfSENSE on USB memory stick - connected on USB
    2. pfSENSE on SD card - inside router case.

    For both of the cases I used same method: download the .img from pdSENSE site and then, using PhyDiskWrite to dump that .img on my card.

    The SD is 4GB card and USB stick is 2 GB
    The SD is using a Nano Card flash, serial console image
    The USB is using a USB, serial console image .

    Because I am using SD/USB to boot, I had to set some kernel parameter.
    Se my post here about these parameters: https://forum.pfsense.org/index.php?topic=77196.msg423350#msg423350

    Also, please be aware that APU board starts with console at 115200 baud rate but as soon as pfSENSE bbots, the console speed decrease at 9600 bps. Therefore, at least at first boot, please close your terminal client and reconfigure it at 9600 bps as soon as you see the booting process started!

    In my above post you will see how to add serial console parameter in pfSENSE configuration file in order to set the speed at 115200.

  • Hi hrts,

    You gave me the answer : reconfiguring my putty serial cnx from 115200 to 9600 bps at pfsense boot and voila!

    Thank you very much!


  • Needed to set the Serial's 'Flow control' in PuTTY to DSR/DTR.

    Otherwise I was not able to type ;)

  • so far so good.
    Now I setup VLAN (n)
    Lan: re1
    OPT1: re2
    still every thing ok
    Bootup complete
    Now Setup Interface IP (2)
    then LAN (2)
    that worked.
    I access the webpage to configure , I can login
    Now I change any settings, for example the timezone and click save
    that works
    Now I want to reboot
    But every time I have to restart with the question about the VLAN setup.

    Its like the save does not work
    What am I missing?

  • Seems good so far. Anything I change seems to be permanent. Try to check search for some logs over the console.
