ST32L476RG dfu bootloader bug via USB?

I have a

firmware.dfu

and

firmware.hex

file generated for the

STM32L476RG

. When I use

dfu-util

and upload the file the system doesn't work, if I use my segger jtag interface and uses

SWD

to upload the firmware.hex file everything works as expected. I noticed that some of the code seems to work when using dfu-util, however it looks like a flash sector or so is missing or corrupted.

If it is a problem, is there an

errata

sheet or something about it?

Regards,

Roland

Pretty sure ST isn't the developer for dfu-util
