Support for Thor configurations is provided in the HSB 2.5.0 release, which is available on github. In the device setup instructions, it shows how to use that tree to program your device with the FPGA firmware that’s released with that tree. Have a look at that and let us know if you have any further questions.
I should add that I am not using Holoscan Bridge COTS hardware like the ones mentioned in the GitHub repo linked above (Lattice/Microchip/Terasic). Instead, I am using a generic FPGA Dev Kit with my own custom logic wrapped around the Holoscan Sensor Bridge FPGA IP that I downloaded from the Nvidia NGC Catalog.
The issue is version 2412 is the latest available on the NGC Catalog and this is too old because the Thor Hololink SDK gives me an error message and calls for version 2501 or later.
