I now have the same problem as the post below:
https://community.nxp.com/t5/Layerscape/LS1046A-PCIe-compliance-mode-set-speed-to-5Gbit-s/m-p/809940
My LX2080 is currently in RC mode, I did the following operation but could not see the 5Gbps signal,
I wonder if LX2080 supports Compliance? How do I configure it ?
1. do a Read-Modified-Write configure write to PEX controller's Configure Space Link Control 2 Register. Please do not touch other bits except the following:
a. Set the Target link speed bit field (T_LS) to the desired speed (0x2).
b. Set the Enter Compliance (EC) bit
There is no link for the pcie signal integrity test。Signal integrity testing has nothing to do with the pcie
link,I need to test Compliance now, but after compliance is configured, the rate cannot reach 5G。
I can confirm that my pcie function is fine because I have tested the pcie function。

Yes I know, we tested pcie at a third party testing facility. The device is connected like this:
1. Now I want to know how to configure lX2080 pcie Compliance test.
2. blow picture is how I'm currently configured, Excuse me, this way is correct ?
3. Whether the CLB is recognized as an EP device
