Hi,

  1. Your idea may not be the right direction. It is common that a pcie device is not getting detected.
    Please follow this document to debug this.

    The “power goes down” is just the result. It is not the cause. Your device cannot link up is not due to the power is missing. It is your device cannot be detected with some reasons so that the power goes off by the kernel.

  2. Yes, it looks like getting stuck in UEFI. You need to enable full log as my previous comment said. We have no solution yet because you didn’t provide any useful information so far.

  3. I actually don’t understand the situation. Does your jetson boot up or not? Does it fail to boot up because of your pcie device?
