[Librem-5-dev] devkit flashing help

[Aaron]

Greetings,

I've had this same issue with my dev-kit since I got it.  I had originally
gotten an externally powered USB-C hub to help with power issues, but I
still had this issue.  The battery idea sounded interesting and I have
tried that as well, with the same results.  I have also tried turning off
the kill switches for the wifi, wlan and camera/mic in hopes to minimize
power consumption, with no success.

How do I get debug port output?  As per the documentation
<https://developer.puri.sm/Librem5/Hardware_Reference/devkit.html>, I have
only found the unpopulated JTAG and UART headers.  I would need to get
headers on one of those to be able to get the debug information mentioned?

Thanks,

Aaron
