PandaBoard-ES Rev B3 - No network connection


#1

Hello,
after proceeding twice with https://www.digikey.com/eewiki/display/linuxonarm/PandaBoard I don’t have any network connectivity (neither eth0 nor wlan0). Had anyone simmilar problem? I have checked on two boards (we have couple of them in office). Also Ubuntu 18.01 is using netplan (not ifupdown).
Br,
Marek

@marverix, which kernel are you currently using? Did the smsc95xx usb module load?

Regards,

Hello Robert!

I send email to eewiki@digikey.com but probably didn’t reached you out, so I will paste part of it:

Thank you for great wiki page about PandaBoard! We have in our company couple of them and those were lying without purpouse because lack of software.

I have followed wiki step by step and PandaBoard-ES B3 is booting (finally!), but it doesn’t see any network adapters.

Also one comment: on Ubuntu 18.04.1 (which I’m using) ipdownup is not longer use - they use netplan. I tried both ways, but still nothing.

I have tried twice - first with everything according to Wiki, and second with other (newer) packages (Linaro 7.3.1, U-boot v2019.1, Ubuntu 18.04.1 2018.12.26).

Kernel which I’m using right now is 4.14.x (previously I tried 4.19.x).

Regarding smsc95xx. I’m attaching log from COM1.

Didn’t found module that you mentioned. Also lsmod shows empty list.


#4

@marverix, please run “sudo depmod -a” we use compressed modules and it looks like your development pc didn’t generate that… (ubuntu finally updated kmod in 18.10 to support xz modules by default.)

Regards,


#5

Should I get any output? Because sudo depmod -a shows nothing.
Br,
Marek


#6

@marverix, it doesn’t output any information, lsmod should show a few modules loaded, otherwise after a reboot more things should be shown with lsmod…

Regards,


#7

@RobertCNelson you are the Life Saver! After reboot worked like a charm! Thank you so much! :slight_smile:


#8

@RobertCNelson Could you help me also with WiFi? Ethernet is working fine (thru netplan), but WiFi is soft blocked by some reason by kernel (rfkill shows it). I tried to unlock it, but it’s going down all the time… :frowning:

I will try tomorrow with new kernel then. Thanks one more time for your time and huge help!

@marverix, does this service file fix it?

Hello @RobertCNelson,
Nope… Command rfkill unblock wifi is not working for me. I mean in theory it is working, but still for some reason wifi is going down. In free time I will try 4.19 kernel. My last idea is to try to calibrate adapter according to TI tutorial.
