PCIe Device is recognized randomly

Hello,

We are testing connect KC705(xilinx) with AGX Xavier.

AGX Xavier find KC705 board randomly while booting.

Those are dmesg for each case.

• 
  

  Recognized
  log_3_fpga_connect_w_ssd.txt (81.9 KB)

  
  


• 
  

  Not recognized
  log_4_no_connect_w_ssd.txt (65.1 KB)

  
  

And we can reconnect it manually as below

1. 
   Unbind : echo 141a0000.pcie > unbind


2. Reset FPGA


3. 
   Bind : echo 141a0000.pcie > bind
   
   And this is the dmesg when we reconnect it manually.
   log_5_forced_connect_w_ssd.txt (124.9 KB)

Anyway, this manual connecting is much of a hassle.

So, we want these devices are connected as stable while booting process.
