Hi,
I have developed a custom PCB for our application.
i have replicated everything regarding the programming Jumpers and programming pins as we do in STM Blue Pill through Arduino.
some how i am unable to program the new chip.
Question in my mind is do we need to load bootloader for programming via RX TX Pins A9 A10 ? Pin no. 30 and 31 ?
Or Bare STM32F103C8T6 can directly be programmed using USB TO TTL ?
Please guide. this is 1st time i am handling STM32F103C8T6 Board.

Re: STM32F103C8T6 Custom Board Programming Issue
you don't need to load a BL, as the system memory BL is available:

So you should be able to flash using PA9/PA10 using USB/TTL. Check all condition are ok.
Pattern 1 Boot0(pin) = 1 and Boot1(pin) = 0
