custom board or NV devkit?

What device in use?

Which jetpack release in use?

4

custom board or NV devkit? NV devkit, connected to fpga via oss cable adapter
What device in use? Oss cable adapter
Which jetpack release in use? 35.4.1, jetpack 5.1.2

5

please try to bind and unbind the pcie controller after boot. FPGA usually needs more delay after boot up.

6

How can I bind and unbind C4 and C5 controller? Let me know the command.

8

Something like

cd /sys/bus/platform/drivers/tegra194-pcie
echo 14160000.pcie > unbind
echo 14160000.pcie > bind
