Flash STM32 Primer over UART1

Get STM32 primer.

Need write about device.

You need TTL3.3v serial port. Example USB to UART Prolific PL-2303 chip.

• Connect TX line of serial port to RxD (sic!) point on primer's board.
• Connect RX line of serial port to TxD (sic!) point on primer's board.
• Connect port and primer grounds GND.

Resolder R48 that would pull-down Boot1 processor pin.

R42 change with 10К resistor.

Connect Boot0 point to nRTS line of serial port or use jumper instead R49 to enter program mode after reset

Connect nDTR of serial port to Reset point via semi-key and/or connect button to Reset and GND points on primer board.

Install python and pyserial library. On Debian type command

apt-get install python python-serial

Download flash loader stm32loader.py.gz

Get help:

./stm32loader.py --help

Erase, write and verify compiled binary:

./stm32loader.py -e -w -v example/main.bin

Loader have bug: you must disconnect serial port after flashing and reset MCU.
