New unit fails UART Loopback test
-
Hi all,
We recently purchased a Voxl Deck (not our first) and our application (which has been running great on other units) wasn't working - specifically we weren't getting anything on the UART line. Sure enough, we ran the included loopback test on UART 12 and it failed - the other ports passed.
Needing only 2 uarts, we moved our application to the other two UART ports... But we find that if one is in use, the other drops out. I assume this is a hardware issue with our unit. Furthermore, we ideally need all three available UART ports for our application so one and a half is a non-starter.
As part of our setup we flash the system image and the issue persists after a re-flash. An identical software setup has worked just fine on multiple other Voxl Decks.
Assuming this to be a hardware defect, we requested a return in private support channel but were instructed to post here instead. Can someone either facilitate a return/replacement or provide other guidance?
