Re: [Crash-utility] using crash for ARM

Hi, I got the crash up on the target but I get following error.

WARNING: kernels compiled by different gcc versions: ./vmlinux: (unknown) live system kernel: 4.4.3

crash: cannot open secondary temporary file

I have taken System.map and vmlinux from the same build path.

If you are talking about running crash on a live ARM system, then option #1 is the only possibility. Option #2 does not exist for the crash utility; live system access requires either /dev/mem, /proc/kcore, or the /dev/crash misc driver. Dave
