Hello

I checked pci driver sources provided for IMX.6 CPU. It seems that ddr memory window reserved for root complex is limited to 16M. I need at least 256M for BAR0 in my application. Is it possible to patch the driver to support such memory size?

Hello,

Only 16 MB address range is available for PCIe in i.MX6 system memory map.


Have a great day,
Yuri
