Plug your ESP8266 device into a USB port on your linux machine (or, if you’re using VirtualBox, map the USB device through from your host to your guest).
dmesg | grep usb
You should see output like this (in this example I am using a Wemos D1 mini - the precise text with vary depending on the USB TTL device you are using):
[90279.476382] usbcore: registered new interface driver usbserial_generic [90279.476412] usbserial: USB Serial support registered for generic [90279.480721] usbcore: registered new interface driver ch341 [90279.480755] usbserial: USB Serial support registered for ch341-uart [90279.481709] usb 2-1.8: ch341-uart converter now attached to ttyUSB1
Note the value provided right at the end - here ttyUSB1 - you’ll need this in a sec.
Install docker if not already installed:
You may need to log out and log back in again at this point so that your user is part of the docker group.
Run the container containing pre-built otb-iot images. Change <usb-device> to the value you noted earlier - in my example this would be ttyUSB1:
docker run --rm -ti --device /dev/<usb-device>:/dev/ttyUSB0 piersfinlayson/otbiot
Once the container has been pulled and run, Flash the device and connect to it over serial:
make flash_initial && make con
Use Ctrl-] to terminate the serial connection.
When you want to terminate the container run:
