Is the Navio2 supplied image RT?

[Mikebert4 (Mike Beaton)]

Just a quick clarification needed from @Emlid

The navio2 rpi image provided in the docs works great (I’ve got APM up and running and everything) - is there a link to the kernel source somewhere?

The only kernel source I can find is for the 3.18.9-rt5-v7+ used elsewhere in the docs for Navio+

A quick uname -r on the installed Navio2 image gives 4.1.6-v7+

Two questions off the back of this:

1. (as above) Is there a link to the kernel source for module compilation?
2. Is this still an RT kernel?

Bumping with an update because I’ve had time to do a proper search of the forums:

Kernel info in this thread is useful -

Any chance we can get this image working on the older Navios? Even if it’s not possible to detect the old Navio chipset (HAT EEPROM?) maybe you coild still keep one RT build and add the old drivers blacklisted in the modules path plus a simple batch script which enables the older hardware. Then you have only to maintain one kernel branch and the older customers have a greater chance they can keep up to date with newer kernels into the future. Then main point of concern are the newer C librari…

@Mikebert4

You can compile kernel modules agains this branch.

Thanks @staroselskiy - I was just this second sitting back down to this! Your timing is impeccable.
