Error in Installing Drivers in RK 3399-PC

penguin

Hi Srikrishna, how do you install the driver?

Do you compile the driver directly on the board?
Then you need to download the full kernel source code
to the board for convenience. The Firefly root filesystem
currently does not contain the kernel headers.

Copy the code

Some regulators have conflict GPIOs, please check your PCIe dts node.

Please check the log quoted before. You have to inspect the GPIOs used in PCIe dts node and dvdd-1v2 regulator node carefully.
