Why does the data-log code furnished with the sensor tile kit not work reliably? I am including all error codes and will copy the complete code if needed. Thanks, Ralph

Hi @RTrim.1 , from the OpenOCD it seems that the .bin upload has properly finished... which error do you exactly refer at?

Regards

Hi Eleon, All I know is that once in a great while, this code will run on the sensor tile, a second com port will open on the host computer using putty and all the sensor readings will update every 1000ms as promised but most of the time nothing happens because the "shutdown command invoked". The complete code is included below. Thanks for any solution, RalphTrimnell
