Problem on downloading bitstream to a Stratix 10 MX board

I see. Thank you so much for the clarification!

But I'm still confused with the inconsistency of DIP switches configuration in the documentation. For example, in the following Figure 3, there is a mismatch between the real board and the explanation in terms of the PCIe RT signal. In specific, the PCIe RT setting in the real board was set to the left side. But the PCIe RT setting in the explanation was set to the right side.

Also, from Figure 3, it seems like SW2-1 corresponds to the board label named "S10". However, the board label named "S10" is actually SW2-4 in Table 3.

Thus I have the following two questions:

(1) What is the real position of "S10"? SW2-1 or SW2-4?

(2) What is the correct explanation of the default setting of SW2?

Thanks,

Hanchen
