Updating BC660K-GL firmware from Command Line

Dear Forum Users,

I am looking for a way to update firmware of BC660K-GL device from command line. Right now I am using QFlash GUI program to flash BC660 modems by hand, but I would like to automate firmware updating to include it in our prouction process.

In the other topics on the forum I saw multiple programs like QFirehose, but their manuals do not mention BC660 so I assume they can’t be used in my case.

Based on the logs created by QFlash I tried to copy command line process called by QFlash :
cmd.exe /c "(…)\QFlash_V7.9\EFlashTool\1\flashtoolcli1.exe --cfgfile (…)\QFlash_V7.9\EFlashTool\1\config.ini --port=“COM7” probe ",
but it failed with an error of:
A fatal error occurred: could not open port ‘COM7’: FileNotFoundError(2, ‘The system cannot find the file specified.’, None, 2)

Is there any official Windows or Linux tool to get it done?

Best regards,
