Jetson Nano as LinuxCNC driver

It runs Linux, has a bunch of GPIO's and appears to be faster than snot.

It would be really cool if there was a project to port LinuxCNC to the Nano. Sadly I'm not qualified to do it, but I'm hoping to drum up some interest since NewEgg only has one or 2 motherboards with native parallel ports available

It looks very promising until it dawns on me that Nvidia does a lot of power saving on everything and they tend to do it properly ( looking at you, AMD ).
I would order it right now to play with it, but i can not due to customs not playing nice here.

Parallel ports are just one of many ways to interface LinuxCNC to your hardware. And the worst way.

There are lots of PCI and Ethernet options.

Actually, GPIO from a synchronous von Neumann architecture is the best idea, but the "way" to it has been clouded and crippled by modern CPU architecture featuring non-von Neumann "improvements", and not providing standard GPIO other than the corrupt and obsolete implementation of parallel ports.

The founding principle and ideal of LinuxCNC is that one computer does it all. The software is free, the computers get better and cheaper, the future is happy!

It's a technical tragedy that you can buy a motherboard with 100s of millions of transistors, but you can't do what you want with them. The hackery of a BIOS or Intel Management Engine owns the real time. You have to add another board, that amounts to another computer, with 1/1000 the complexity and 1000 times the price/transistor to fix that.

Something like the Jetson Nano might give back control of these factors, if you can control the GPUs or cores. But figuring that out will be a huge effort.

I miss the days of Multibus and ISA.

I don't !
To much fiddling to make it work.
While we are at it, Token Ring anyone ?

Token Ring, wow, you are no more the joungest in class?
Haven't heard that since years...
