Our boss just replace i.mx6Q with i.mx6DL for our product(using SDK_3.0.35-4.1.0), and it was almost a success. but we got some defect product which always hang up at PCIe initialization.
our HW team told me the signal on PCIe TX pin of the i.mx6DL is too high; and i.mx6Q seems have no this issue.
I just check the kernel source to see if there a way to change the resistance about the PCIe TX pin; but I can't find it,
I can only change all pins defined at kernel_3.0.35/arch/arm/plat-mxc/include/mach/iomux-mx6dl.h, and there seems no PCIe TX pin define here.
Any suggestion would be help, thanks.
