udoo problem connecting json server to arduino-due
I still am having problems getting the serial-port-json-server to connect to the arduino-due on the UDOO board. The verbose output is listed here: udooer@udoo:/etc/init.d$ sudo service serial-port-json-server start

I wonder if the seriallist_linux.go would find the /dev/ttymxc3 port if it used getListViaTtyList() rather than getAllPortsViaManufacturer() in lines 25-26? Are there other changes that would be necessary if I compiled it changing those lines?
If you open a port directly with SPJS it should just open, regardless of whether it is in the port list that SPJS sends you. So the fact that it still doesn't seem to be able to open your port is a bad sign and seems more of an issue outside of SPJS. Are you able to connect to /dev/ttymxc3 from other apps successfully?
With respect to the port list, yes, you should try tweaking the code in seriallist_linux.go. It would be cool to try to fix getAllPortsViaManufacturer() to recognize your ports and then do a pull request because then it could benefit others. You could swap to getListViaTtyList() just to see if it helps, but you lose all the dual port detection of the TinyG G2.
I was able to upload tinygg2.bin to the Arduino on /dev/ttymxc3 using bossac. Also I can see the initial code on loading Udoobuntu v2 (14.04) so I believe that the port works.
I compiled serial-port-json-server on my amd64 machine changing the seriallist_llinux.go code at line 25-26 and it compiled fine and listed my tty ports. I will try to compile it on the UDOO using dave chaney's unofficial go for ARMv7 multiarch.

With the compiled serial-port-json-server, I got the Chilipeppr logo simulation to run.
It still says that there are no serial ports found on the json server
