Python API to automate STMicroelectonics flash using ST-Link CLI Utility.

Required Packages:

• pywin32
• pypiwin32

Hardware used

ST-Link V2 that comes with STMicroelectronics Nucleo development boards. These ST-Links also provide USB-to-Serial ports.

Supported programmers

Check ST-Link Utility guide.

How to install and use

There aren't any installations. Clone the repository and use the methods. There are only two public methods:

• findall()
  This method returns all the ST-Link Probe number and corresponding COM port number.
• flash(hex_path, probe_no)
  This method takes the hex file path and the probe number (default = 0). It returns status ('successful' / 'failed') and the checksum of the hex/binary file.

Example

import stlink

if __name__ == '__main__':
    print(stlink.findall())
    status, checksum = stlink.flash('G:\\test.hex')
    print(status)

Output:

[{'probe': '0', 'com': 'COM4'}]
successful

pystlink's Issues

Not able to burn .bin format

I've been facing issues burning files in .bin format. I've tried .hex format and they work well, but most of the code we generate is in .bin and we don't want to convert it back to .hex format. Is there any way I can use .bin format?
