Dear Eric,
Thank you for your answer. Indeed, what I need is "Bittworks II Toolkit Lite". The issue is that the tool is no longer available for download anywhere after the support has been terminated on July 31 2020.
This is the response I received from Bittworks: "As of July 31, BittWare no longer provides support or access to tools/updates for Intel PAC. Please contact Intel directly for assistance."
So far I have not been able to obtain the tool neither from Bittworks nor from Intel. Meanwhile I have managed to make contact with the vendor (Mouser Electronics), but the issue remains unresolved.
Kind regards,
Rok
