I have yet to open up my new Telos and have not seen this is an photos. Is there a set of pins to support the use of a serial monitor so I can log boot time kernel activity? I was able to do this with my Minix Neo X5 and that helped me solve some problems and get some kernel modules working properly. Thanks

Just a note for others... It is my understanding from the kind folks at CNXSoft that while there may be a connection on the board for this purpose, there are no pins in place. So some soldering would be required (not my forte). But I did find what may be a good enough solution for my needs. See Chainfire's LiveBoot app on Play Store <play.google.com/store/apps/details?id=eu...nfire.liveboot&hl=en>.
LiveBoot requires root and a my technique requires a custom recovery (I have been using Aleha's TWRP). In addition to displaying kernel messages and logcat information starting just after /data is mounted, this app can optionally put the same information in a file called /cache/liveboot.log.
If your system crashes/freezes during boot and you want to see this information for clues, this file can be retrieved before it is overwritten on the next boot by booting into the custom recovery, chmod'ing the file, and copying it onto the internal SD card.
There may be other ways to accomplish the same thing. But this is fairly easy if you have root and a custom recovery like TWRP.
