I'm working with the SMP affinity on an i.MX8 system (on a SolidRun HummingBoard Plus) and there are a couple of things that confuse me, but mostly that one of the affinities keeps changing.
It's for a timer interrupt, e.g.:
root@sr-imx8:~# cat /proc/irq/6/smp_affinity
4
root@sr-imx8:~# cat...
I can recommend the O'Reilly book "Making Embedded Systems" by Elecia White as a general resource for embedded programming.
For a book that focuses more on specific hardware, see the Embedded Systems books (intro to cortex-m microcontrollers, real-time interfacing to cortex-m microcontrollers...
This indicates that the system you're trying to run on is very different (different version of the C library) from the one you're trying to run it on. Make sure that whatever software you've downloaded is for your system (RedHat 6.7, it seems?) and not generally for Linux/another version of RedHat.
Does anyone know of any Linux distros that are certified to safety standards like ISO 26262 or DO-178B/C?
I've been tasked to research this area in general but I'm not coming up with much, any pointers would be appreciated!
