Python script to debug my binary using gdb on QNX OS

Question

OS: QNX 11.1 Python: 3.10 Host OS: Windows SDP: qnx710

I'm trying to debug my application which will be running on QNX. When I execute the below python program, it doesn't execute os.system('file {}'.format(binpath)). It just stopped at gdb prompt.

##Test Program
import os
import subprocess

ip_to_check = ('***.***.*.*')
targetIP_Port = ('***.***.*.*:****')
qnxPath = ('C:/qnx710/host/win64/x86_64/usr/bin')
binpath = ('D:/Project/develop/sample')
#FILE = ('gdbInit.txt')

os.system('cls')

returnStatus = os.system('ping -n 4 {}'.format(ip_to_check))
print('\n')
print('#'*60)

if returnStatus == 1:
    print('Please check the target connection, restart and try again...')
    print('#'*60)
else:   
    cwd=os.getcwd()
    print("Current Working Directory: {0}".format(cwd))
    print('\n')
    print('#'*60)

    print('Changing Directory to qnx path')
    os.chdir(qnxPath)

    cwd=os.getcwd()
    print("Current Working Directory: {0}".format(cwd))
    print('\n')
    print('#'*60)

    os.system('aarch64-unknown-nto-qnx7.1.0-gdb.exe')
    os.system('file {}'.format(binpath))

If I manually execute in command prompt, the symbols are read.

C:/qnx710/host/win64/x86_64/usr/bin/aarch64-unknown-nto-qnx7.1.0-gdb.exe D:/Project/develop/sample

Has anyone tried to automate remote debugging the application using gdb on QNX OS. Can you please point out what is wrong in the above script?
