Hi.

I am testing with the ST Discovery Lora Kit, B-L072Z-LRWAN1.

Dfuse Demo (v3.05) does not download firmware properly.

The error message is shown below.

The following image is the contents of the option byte.

There is no revision.

A similar error has been found in the STM32L0 series.

Is there a problem with the STM32L0 series?

Please give me the solution to the above.

Well the error you've provided just indicates you have a generic STM32 L0, which can't be differentiated from millions of others, or thousands of other customers products using an L0, and not with some unique VID/PID to you as a customer.
