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.

Hi all

We have exactly the same two problems with STM32L083KZT6. Is there any chance to solve that issue (programming STM32L083 via Windows dfu).

Many thanks

Steve

I had this same issue and ST gave me a Pre-Release version of the DFUse(V3.0.6) Software today and the problem has been fixed.

I have the same problem with latest version of DfuSe program release (v3.0.5) using a STM32L073 MCU.

@Mo Nakhuda: I asked to ST via its support platform to give me a version v3.0.6 release, but they gave instead

a v3.0.3 version that is not stable (it crashes at the exit program and it always generates an error on a verify phase).

I again asked them to have the v3.0.6 but they didn't respond.

How did you obtain the version v3.0.6? 

Thanks in advance to everyone can solve the problem.
