I have a Problem with the DfuSe Demo (v3.05) and the STM32L073CZT on chip bootloader.
It is not possible to upload or down Load from/to the InternalFlash.
Downloading or Uploading the DATA Memory is possible.
I have tried it with our own borad and a nucleo board both the same problem!
Does anyone knows what the problem is?
Is it a Problem from the STM32L073CZT chip or from the DfuSe Software?
today i tested it with the DFU Tester (v3.0.1).
there the Flash is also shown as not readable writeable.
but it is possible to write or erase the Flash, also leave dfu mode works.
