Weird behaviour: input/output error and no commands after few minutes

I requested and got a refund the next day.

As far as I remember I tested it with original and updated BBB image and the problem persisted.

Argh, waiting on a pile of JST-XX connectors to get the Blue-world up and running. But thanks!

I happen to really like the https://www.seeedstudio.com/Grove-Universal-4-Pin-to-Beaglebone-Blue-4-Pin-Female-JST-SH-Conversion-Cable-10-pcs-pack-p-3026.html to get to 100-mill connections where I can simply plug in jumper wires. I use those connectors for Grove modules with Blue as well.

Regards to your challenges with what sounds like your root file system becoming unreadable (unable to execute commands), are you monitoring heat and power in any way? Is there free room on your root file system? Indeed getting a serial log should help you see what kernel errors are happening, but I’d be cognizant of what environment your running in when creating posts.

BTW, the network connection is typically supported through connmanctl rather than /etc/network/interfaces.
