Flashing XC886 using ULINK2

Lukasx

I would like to automate flashing process for my Infineon XC886 devices.


Currently, I use ULINK2 and I connect to my board via JTAG
https://developer.arm.com/documentation/101407/0540/Command-Line/Program-Flash-Example
and then I call the UV4.exe via command line. This command opens up Keil uVision5 and flashes the application to my MCU. This process works but is not convenient for production since it opens up Keil application everytime I flash my devices.

Can I use uv4.exe in headless mode (not opening application) or should I use different tool/method to flash my devices? Perhaps someone could suggest an alternative?

    I have been able to achieve this by simply running the command via Python and reading the log file in real time as the log file is being written to.

    from subprocess import Popen, PIPE, STDOUT
import os
import re
import time
import threading



def log_subprocess_output(pipe):
    for line in iter(pipe.readline, b''): # b'\n'-separated lines
        print(line)

KEIL_EXE_path = 'C:/Keil_v5/UV4/UV4.exe'
LOG_FILE_PATH = 'test_log.txt'





def tail_f(filename):
    with open(filename, 'r') as f:
        while True:
            line = f.readline()
            if line:
                print(line, end='')  # Print the new line
            else:
                time.sleep(0.1)  # Wait a bit before checking for new data

process = Popen([KEIL_EXE_path, '-f', 'test.uvproj', '-j0', '-l', LOG_FILE_PATH], stdout=PIPE, stderr=STDOUT)

# Run tail_f in a separate thread to print log file in real-time
log_thread = threading.Thread(target=tail_f, args=(LOG_FILE_PATH,))
log_thread.start()

# Wait for the process to finish
process.wait()

# Join the log thread
log_thread.join()


    The above script allows me to flash the device without running GUI and monitor the result
