Stratix 10 GX SI Board - issue with the Board Test System (BTS)

We recently purchased several Stratix 10 GX Signal Integrity development boards and would appreciate your advice regarding an issue with the Board Test System (BTS).

When attempting to program the FPGA using the .sof files available under the Configure tab in BTS, none of the designs can be successfully programmed. The system consistently reports:

“Detected bts_config.sof on FPGA.”

It appears that the FPGA remains running the default bts_config.sof, and the selected configurations do not load as expected.

This happens when the Quartus version in the QUARTUS_ROOTDIR is the Quartus standard.

If I change it to Quartus Pro version ( I tried 22.1 24.1 and 25.1), the BTS will not be open, and it gets stuck at "Setup connection to System Console server".

Could you please let us know whether this is a known issue and advise on how to resolve it? I think it might be related to the version of Quartus we use. If so, please can you suggest which latest version we should use for the BTS?

Thank you very much for your assistance.

Best regards,
