Flashing XC886 using ULINK2

Thanks. That is useful information, I had this doc opened before but somehow missed the -j0 part. I have been able to program the device without opening GUI, however that is still not ideal for me. Since messages are suppressed there is no way for me to confirm whether the flashing has been been successful.

It would be ideal that after the succesfull programming it would print or return something for me to be able to determine whether some kind of error has occurred or everything executed properly.

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()

Thanks for sharing your solution, Lukas
