I used STMCube Programmer v2.16.0 yesterday to update both my TinySA and my NanoVNA-H4 successfully. ? I just used the "Full Chip Erase" function (using the button to the right of the programming panel) before "start programming".?
I presume it would also work if you use the "Automatic Mode" and check the "Full chip erase" box.
It appears that in this version they have separated the erase function from the programming.? In the "Log" on v2.15.0 you see lines showing blocks being erased during the programming; those are not present in v2.16.0.
Note that this version also uses the Win10 default "STM Bootloader" driver, no need to install the "STM Device in DFU mode" driver required by nanovna-app and dfusedemo.? (And my earlier mention of v2.16.1 was a typo)
