Re: Problem uploading to STM32F103C8T6 board
Also search Youtube for help. This video is a couple of years old but it looks similar to your hardware: https://www.youtube.com/watch?v=Tm7IWQLrKYs

Re: Problem uploading to STM32F103C8T6 board
As mentioned elsewhere in this forum, most of these boards come with the flash write protected and have to be unlocked before general use. Is your led blinking with both jumpers set to 0? Also, the quality control on these boards is awful. You should buy at least 3 boards in hopes that one of them i...

Re: Various problems with bluepill, stlink and serial
With BOOT0=1, press reset. It should not be blinking. BOOT1 is next to the reset switch, BOOT0 is near B10 and B11.When I select BOOT0=1, the blink sketch continues working.

Re: Various problems with bluepill, stlink and serial
Every blue pill I've had came with the flash write protected. You will need to use a tool such as stm32flash. $ ./stm32flash -h stm32flash Arduino_STM32_0.9 http://github.com/rogerclarkmelbourne/arduino_stm32 Usage: ./stm32flash [-bvngfhc] [-[rw] filename] [tty_device | i2c_device] -a bus_address Bu...

Re: Compilation? problem with Arduino 1.8.12 and Olimexino STM32 board
I have a board with a similar disconnect circuit. In setup(), I set the disconnect pin to an output and digitalWrite the pin low so that the 1.5K resistor is always in the circuit. Put a Serial.begin() in setup. In the USB menu, enable CDC generic serial. Upload using ST-Link and the USB Serial port...

Re: STM32 Resets the com port problem
Are you using Serial USB? If so, the USB port will disappear every time your smart board is reset. To work around this, you would need to attach a USB serial to TTL adapter on one of the USARTs and redirect your serial output. This will let your serial port will remain open during a reset. Another i...
