We got a question in OpenHours today that I couldn’t quite field. Assuming I understand correctly, the DragonBoard 410C exposes its GPS via SSBI. It then has a kernel module that exposes it as a tty. Do we have this included in the DragonBoard kernel snap? Covered by an interface? Has anyone experimented with GPS on the DragonBoard using Ubuntu Core?
nope, not yet (it isnt so easy to carrying around a dragonboard to get a GPS fix) … but i’m happy to add an interface if someone tells me the device name and data …
Hi guys (@kyrofa, @ogra), any solution for this issue?
I’m having also difficult to using the GPS on DG410C.
as i understand it the kernel would need the following config options enabled:
probably @ppisati can chime in here as the kernel maintainer and tell us if we have these bits …
along with that there are userspace parts that you’d need to ship in your snap to initialize the dsp (which drives the GPS chip) … this is called qdsp
there are some hints to git trees and such in:
