Internet visdom is that it's corrupted translation table and that secure erase or firmware update might help.

This I assume reseted traslation table on ssd. First invocation of smartctl complained that I have to use -s on to turn smart on, so I did.

And it seems to work. All smart counters are reset (beacuse smart was off after secure erase).

This doesn't boot on x200 dual-core for me.

Different to board on this page, mine has following markings:

boot loader mode

Short GPIO0 and GND during boot to enter flash mode before connecting to the serial programmer. The power indicator LED will be strong red to confirm the device has entered this mode. As soon as the short is removed, the red color will be dimmed. The device will then be ready for flashing.

TL;DR -- it doesn't work for me at all -- it reboots when I access web page and doesn't send data over mqtt or influxdb reliably. I can't recommend it at all, but I'm leaving my attempts below....

connect to first boot AP

When asked for credentials, enter "admin" as username and "fibonacci" as password.

I configured mqtt and start pushing data using telegraf to influxdb. json doesn't work with telegraf.

Is version 1.13.6-dev broken?
