STM32F103RDT6 Bootloader

Post by hyur »

I made a PCB with the STM32F103RDT6 mounted on it.
Some of the designed circuits are as follows.
//
USB DP, DM : NC (PA11, PA12)
FTDI : USART3 (tx : PC10, rx : PC11)
RS232 : USART1 (tx : PA9, rx : PA10)
BOOT0,1 : LOW fix (NC)
ST-LINK : SWDIO, SWCLK, NRST (PA13, PA14, NRST)
//

Because of the above situation, BOOT0,1 cannot be controlled, so USART Bootloader upload is not possible.

So, after putting generic_boot20_pc13 bootloader on Flash with ST-LINK, I want to upload firmware with Arduino IDE by connecting only USB port like STM32duino.

I don't know if generic_boot20_pc13 is suitable for the STM32F103R series.

What I want to talk about is that like bluepill, after uploading the bootloader once, I want to upload the firmware (Arduino source) comfortably.
In particular, it would be nice to be able to upload firmware through FTDI.

Is this possible on my current board?
If not, please tell me why

There is not enough concept in this part, so I do not understand it well even if I search for the material.
Thanks in advance for your help.
