Hi Guys! :slight_smile:

I accidentally formatted my SD card and now it wont boot…
the log says:

Any idea to get the configuration on the SD card again?

You need seven files in the SD card root directory. You can find the latest versions in the IoTaWatt git at


There is a directory called SD that contains the files. Download the git and copy the files from the directory SD to your SD card. Should boot up fine after that.
