Thus it seems to be a variation of the cold boot problem. It looks like the FPGA is not awake at that moment, or is in an incorrect state to correctly respond. In your case the system is waking up and already knows there is a device on the PCIe bus. This latter has solutions posted in the forums. Since the Jetson’s PCIe hot plug detect is not implemented, this means resolving the cold boot issue requires either of (a) making the FPGA turn on prior to the rest of the system, or (b) modifying the system to allow late detect. I couldn’t tell you how to fix this, but do you know if the FPGA wakes up as fast as the PCIe?ĭuring normal cold boot, if an FPGA takes too long to respond the system thinks there is nothing on PCIe, and powers this down.

It could be the issue of PCIE controller’s driver? We connect FPGA to one PCIE port,but after wake up system from standby, there will be endless PCIE error log.
