Hello

I just need a confirmation.

Is there really no support for firmware upgrade over USB (DFU) in the STM32L0 MCUs???

The STM32L0 is not listed in the

http://www.st.com/st-web-ui/static/active/en/resource/technical/document/application_note/CD00264379.pdf?s_searchtype=keyword%20

document.

But in the CubeMX tool the DFU usb profile can be selected for STM32L0 MCUs.

Is DFU supported or not?

Thank you

The 4K ROM in the L053 doesn't seem to be adequate to support USB/DFU.

Perhaps Cube referencing a FLASH based DFU loader?

Hi fischbach.paul,

If you refer to table 3 of

http://www.st.com/st-web-ui/static/active/en/resource/technical/document/application_note/CD00167594.pdf

, you should find the information that DFU bootloader is available for STM32L07/L08 devices.

Then, AN3156 will be updated to include STM32L0.
