Hello, I just tested the following ipipe patches on arm32:
https://xenomai.org/downloads/ipipe/v5.x/arm/ipipe-core-5.4.107-arm-1.patch https://xenomai.org/downloads/ipipe/v5.x/arm/ipipe-core-5.4.93-arm-0.patch applied of course on the appropriate 5.4.x code base, configured with the sama5_defconfig kernel configuration, and in both cases the build fails with: In file included from include/xenomai/cobalt/kernel/thread.h:26:0, from include/xenomai/cobalt/kernel/sched.h:24, from kernel/xenomai/intr.c:24: kernel/xenomai/intr.c: In function ‘inc_irqstats’: include/xenomai/cobalt/kernel/stat.h:61:49: error: passing argument 1 of ‘atomic_long_xchg’ from incompatible pointer type [-Werror=incompatible-pointer-types] __prev = (xnstat_exectime_t *)atomic_long_xchg(&(sched)->current_account, (long)(new_account));
