I have a Nucleo board with a new MCU, base board is the Nucleo-G070RB. Now it is a ST link with a STM32G0BORE.
I have a problem with the internal bootloader where i cannot upload a new program via USB DFU.
There is no hardware problem because VCP works just fine. No data corruption of something.
I have tried .HEX .BIN and .ELF all have the same problem.
This is the error log is have:
