Enable PCI

I'm trying to use the PCI bus to communicate with a FPGA.

In the device tree I had to disabled the PCI bus during bootup, since it got stuck during bootup because the PCI bus could not link up (EP mode).

The FPGA won't be loaded until the Linux is booted up, how do I enable the PCI "driver" after the kernel is up and running?

Thanks,

Niklas

Hi Niklas

please check sect.40.2.2 Kernel Configurations

attached Linux Manual. Note, PCI Express support can't be built as a module.
