As the title says, I don’t know how to expand the Apalis TK1 PCI express from 1 lane to 2 lane.
I am using the Apalis TK1 with a Zynq 7015 and want to realise a communication between these two models with the PCI express.
I tried to look at the board-apalis_tk1-pinmux.c but don’t find the PCI express pins.
Can you share a schematic of your carrier board?
Here is may schematic and the connection between Zynq and Apalis
Did you look at my answer as given here?
Yes I saw and studied it.
I know that it is possible, but now I try to figure out how to enable the second lane.
How to configurate it that I can use it with my connection.
Thanks for your fast answer.
You can try running mainline kernel, it should support PCIe x2, but as mentioned earlier it was never tested/investigated due to lack of hw.
