Question

OTP memory howto?

I'd like to read and write OTP memory with STM32CubeProgrammer, but this does not seem to be possible via SWD.

Error: STM32AP OTP programming commands are not supported with JTAG/SWD debug interface

The subject of OTP programming seems to be missing from the User Manual. Given the potentially destructive nature of the operation, I'd like to ensure I am programming my device properly.

I tried using DFU via USB:

Error: OTP programming is currently not supported on STM32F & STM32L devices

So, a complete bust for me. When is this expected to be supported?
