Hi @xwuupb,
If I remember correctly the mention 'intel_s10sx_pac:pac_s10_usm' are BSP for Intel PAC D5005, and suspect there would be some interconnect differences. (Note: no hard trying to compile and program but likely it would fail or not behaviour correctly)
Noted on the hardware involved, unfortunately as it is coming from Bittware, we would need them to provide the correct workable BSP to continue. Hence would suggest to get in touch with their support channels and provide them with the references design you are using to understand further.
Hope that clarify.
Best Wishes
BB
