Part Number: TDA4VH-Q1

Tool/software:





Hello, there is a description of LCPD-37899 on our SDK10, which has solved the speed issue of PCIe. I couldn't find the corresponding modification in our TI kernel. Can you help confirm which modification it is? 
We look forward to your reply!

    Hi Quansheng,

    It should be a change to the generic endpoint driver for PCIe: drivers/pci/endpoint/functions/pci-epf-test.c. You may clone the kernel source code and run something like "git log --follow drivers/pci/endpoint/functions/pci-epf-test.c" to see the commits made and compare against your version of the SDK/kernel.

    Regards,
