About two AGX Xaiver use PCIE connect

Hello, Nvidia

We designed a custom board, which can insert two AGX Xavier by default.

On the board,

we used PCIE to connect two AGX Xavier by default. So far, it works well.

However, we found that after configuring EP Xavier, we need to restart RP Xavier to correctly identify EP Xavier. But the normal logic of our board is to enable two AGX Xavier to start at the same time.

Do you have a way for RP Xavier to recognize EP without restarting? Maybe it’s a good idea to reset the PCIE driver? But I don’t know how to do it.

Thanks.
