be willing to invest this kind of money, my tarket was to establish a
development platform for engineering offices. I
Well that was my point in my previous comment. Whereas I think QNX is a
really great RTOS hopefully brigded to opensource -whereas being closed
source- in recent years (yes recent compared to 20 years of existence) ,
from the start I've believed in the µKernel architecture as the best one.
Anyway,

I think you are going about it wrong. I would start by adding a device to
the bus and them with the basic commands like i2cdump, i2cget, etc, control
it.
If you want to learn Linux internals, that is great, but start at the
device driver. assuming you know how the kernal works.

The BeagleBone Black ethernet interface will fail after a few hours of
operation. As an example, we did a fresh install of both Debian and Ubuntu
on two Beagles (Newest updates for the Arm OS), connected them to the
network and sure enough the next morning, both of the interfaces had
failed.
So if the board never works again, have you sent it in for repair via an
