We have a problem downloading to the STM32L100 processor. It was programmed using STLink. Now we want to use STM32CubeProgrammer. Writing is not possible! It is not possible to change the RDP value either. If we use STLink, all is OK.

We had an old version, v2.8.0. Now we have a new version v2.9.0 and it works fine!

Thanks for the warning and I'm sorry, that should have occurred to me.😉
