on Raspberry there is a config file on /boot that allows tweaks and over clocks?
on Banana Pi there is the TDB file one can tweak in kernel source;compile and replace the /boot/dtb/* one?

You can use the dtc (device tree compiler) to rebuild the binary blob (the "DTB") like this:

so that's what its for?

Ok so for USB 3, only put "xHCI support for NVIDIA Tegra SoCs" as a module and it will work (4.9.0 kernel).

As a note, fuse is not activated in the tegra defconfig.

Has anyone solved the black / blank screen problem ?

With recent kernels, the HDMI out sends no image. Reverting to the official pre-compiled Nvidia kernel make the screen working again.

the official one is an 3.x kernel, right?

The working one I use is the 3.10.40

warning, rant ahead:

It seems, anything that is solved on ARM is solved on the 3.x series of kernels?

Since the mainline moved to 4.x, it's either use an old "feature rich" one or use an recent one (kernel) lacking proper support?

In the meanwhile (while we waited) the Raspberry Pi (arm v6) became (even!) obsolete and will never have both recent kernel and video acceleration anymore.

I can't but wonder will the same fate strike any of the other SBC devices of the v7 series too, now that the AA64 has approached production phases?

Does anyone knows how to activate the console screen ?
I can run X and have a display, but nothing without X.

Also, I have a poor choice of resolutions under X.
