VIM3 Firmware upgrading - no mouse and keyboard

My test was with image on 20191228.
And yet, it’s ALL about 20191231. After re-flashing 20191231, my khadas VIM3 won’t let me login, I mean: mouse and keyboard don’t work.

Now, how to disable PCIe? And, does that mean: there is one interface working at the same time? Either PCIe or USB? What’s more, how do I know if I successfully have PCIe disabled? which command to show that?

Cheers
