Reset when try to connect to Bootloader (USB)

STM32L073RZ

We are entering the BL via boot0. The STM32Cube Programmer software sees the USB port but when I try to connect, the part resets out of the bootloader.

Appreciate any ideas.

Thanks

Rich

Well I am glad it is not a bug in my code or worse yet the bootloader.

When will the next rev be released?

Are there other software tools that support the USB bootloader?

Thanks

Hi @RSoen.1​ 

You can use the Dfuse tool available on st.com.

Please pay attention that drivers for STM32CubeProgrammer and Dfuse are not compatibles , You need to remove manually the CubeProgrammer driver before using Dfuse.
