11.5.8. Try A Different PCB
Multiple instances of the same PCB, or multiple instances of the same interface, on physically different hardware platforms may exhibit different behavior. You can determine if the configuration is fundamentally not working, or if some form of marginality is involved in the issue.
Issues are often reported on the alpha build of a development platform. These are produced in very limited numbers and often have received limited bare-board testing, or functional testing. These early boards are often more unreliable than production quality PCBs.
Additionally, if the IP is from a previous project to help save development resources, determine whether the specific IP configuration works on a previous platform.
