I don't have a pdk and it's difficult to find them so I need to check. Anyway some revision of the firmware on this pendrive are working but the latest one is not working. I have a lot of pen drives and all of them are fully working. > Benoît brings a good point: what is the exact pin that causes the USB > failure on your case? I have tested only with uart and already it does not let it work properly. So I can try to limit in my boot case but I don't think that having SION bit pre-defined it's valid at all. We have a limited number of pin mux with SION enable on any nxp architecture right now for every architecture. * Benoit * can you test them? I will provide a better changeset let sdcard and some ethernet pin in the right configuation (even ethernet was working without SION enable) > > Let's try to understand the exact pin that is causing the problem on your > board. > I will check it out.
