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, fo= r 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/mas= ter/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian and I have also tri= ed 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, X= ENO_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"?
