Hardware: board bluepill stm32f103cb (gd32f10x, ARM Cortex M3) NRST button on R active low Boot0 button active high Key user-button available at PA0 active high PA12 have a pull-up resistor Blue Led PB2

Development environment: Platformio

My customisation: Config.h // added

elif defined TARGET_GD32F1_GENERIC_F103_PB2

#define LED_BANK GPIOB
#define LED_PIN 2
#define LED_ON_STATE 0
#define FASTBOOT 1

else

Makefile and platform.ini adjusted accordingly.

Problem: Program uploaded via bootloader only starts with serial terminal connection. With reset or poweron-reset only bootloader is started. Without fastboot, the blue LED flashes according to the bootloader programme (very fast, fast and off). What adjustments would I have to make so that the uploaded programme starts without a terminal connection via poweron reset?

With the bootloader https://github.com/WeActTC/BluePill-Plus/blob/master/SDK/STM32F103C8T6/Arduino/Bootloader/STM32duino-bootloader-PB2.bin poweron-reset does not work either.
