Subject: [Xenomai] Illegal instruction/bad syscall
Date: Tue, 24 Apr 2018 12:38:06 +0000 [thread overview]

Hi!
I recently managed to run a cobalt core for raspberry pi 3, Im using ipipe #9 for arm, kernel version 4.1.21, Xenomai 3.0.6.
I managed to build the xenomai API but when I try every executable file, for example latency test bench, I get "illegal instruction", and in dmesg I get "[Xenomai] bad syscall <0xff7000af> ...".
The crosscompiler Im using is https://github.com/raspberrypi/tools/tree/master/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian and I have also tried compiling it on the RPI3 itself but Im getting the same error.
I have compared my kernel config next to Harco Kuppens working image (http://www.cs.ru.nl/lab/xenomai/) But the only difference is that I have higher values in XENO_OPT_SYS_HEAP, XENO_PRIVATE_HEAPS, XENO_OPT_SHARED_HEAPSZ, XENO_OPT_TIMERS.
Im uploading a readme with the steps I have taken with the installation and also my kernel config.
Any ideas on why I get "Illegal instruction"?
Regards
Gustav Johansson
