[cip-dev] B@D: mapping serial device to the VM for ser2net

[Daniel Sangorrin]

Hi,

I'm trying to setup ser2net for LAVA to access the serial port output of the 
Renesas iwg20m board via local telnet from within the B at D virtual machine.

I managed to get it working by using the Serial port settings window at
the Oracle VM Virtualbox Manager (GUI). In particular, I used port mode 'Host Device'
and '/dev/ttyUSB1' for the Path/Address (the device file name on the host).

That maps the host's /dev/ttyUSB1 to the VM's /dev/ttyS0, so I also had
to modify the /etc/ser2net.conf file and specify that port 2000 is supposed
to use a 115200 baud rate.

Although works fine (telnet localhost 2000), I see that you guys are using the 
port 8020 for /dev/ttyUSB0 by default so I was wondering if there is a better strategy. 
# I have also tried using the "USB" settings in the Virtualbox Manager (after installing 
# the extension pack), but I haven't figured out how to it works yet

Thanks,
Daniel

For the USB settings have you tried the config suggestions at the end of this page:
https://wiki.linuxfoundation.org/civilinfrastructureplatform/beagleboneblackboard
points 15-16 intended for windows but should also work with debian

I don't remember changing my local ser2net.conf and wondered whether
8020 was a default (or is that what you're saying), but it's been quite
a few months since I set it up!

Yes, I had already tried those instructions but I couldn't see any devices showing up on my Virtualbox manager.
I solved the problem with these instructions:

$ sudo apt install virtualbox-ext-pack
$ sudo adduser $USER vboxusers

Now I can see the USB devices as in the instructions. Thanks for your help.

Regards,
Daniel
