Notes: serial bootloader speed seems to work up to 115200 (at higher speed often it doesn't work) Notes:
1) Serial bootloader speed seems to work up to 115200 (at higher speed it often doesn't work)
2) Serial bootloader works only when USB port is disconnected (otherwise the MCU starts in DFU mode). So, in case you put this MCU on a Bluepill PCB, you need to power the MCU from 5V or 3V3 pin and not with USB cable.

You can replace the MCU on the Bluepilll board with the AT32F403A. It is pin fully compatible. You can replace the MCU on the Bluepill board with the AT32F403A. It is pin fully compatible.
Just need to replace BOOT0 resistor from the present value of 100K with the value of 10K. This will allow the MCU to enter in Bootloader mode and flash it via UART1.
