I am also trying the same thing with a bluepill and blackpill however I am unable to program it that way. Can you tell the steps you followed to do this ? Thanks

Note that Blue/Black/other-coloured "Pills" are unlikely to have genuine STM32 chips, so their behaviour cannot be guaranteed or supported by ST - especially in "unusual" configurations like this.

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
