This repository is a re-distribution of Ivan's project (Project page: http://tuxotronic.org/wiki/projects/stm32loader)

In the original version, using this script need to corporate with the set and reset on BOOT0 and RESET pin. The set and reset usually were executed by hand. To create a totally automatic download process, you need to modified your hardware stm32 devices. Following are the steps you need to follow:

1. Identify you UART-to-USB Chip you are using and find the RTS and DTR pin.
2. Connect the RTS pin on your UART-to-USB Chip to the BOOT0 pin on you STM32 device
3. Connect the DTR pin on your UART-to-USB Chip to the RESET pin on you STM32 device

Note: For the connection of pins in steps 2 and 3, you can change the order in an opposite way(RTS->RESET, DTR->BOOT0). If you do this, you need exchange the usage of setRTS() and setDTR() functions in bootloader.py.

Python script which will talk to the STM32 bootloader to upload and download firmware.

Usage: ./bin.py [-h help] [-p port] [file.bin] -h This help -p Serial Port, default "COM6"

./bin.py -p "Port" example/main.bin

Example: bin.py -p COM5 somefile.bin

This will pre-erase flash, write somefile.bin to the flash on the device, and then perform a verification after writing is finished.
