Hello
I'm using xenomai in a qemu setup.
My final goal is to use xenomai to port extisting pSOS application to the
linux platform.
The first step I did was building a kernel with the pSOS skin enabled. These
traces are generated at kernel startup:
[ 0.212363] I-pipe: Domain Xenomai registered.
[ 0.212363] Xenomai: hal/i386 started.
[ 0.212363] Xenomai: scheduling class idle registered.
[ 0.212363] Xenomai: scheduling class rt registered.
[ 0.246987] Xenomai: real-time nucleus v2.5.4 (Sleep Walk) loaded.
[ 0.246987] Xenomai: debug mode enabled.
[ 0.274658] Xenomai: starting native API services.
[ 0.274658] Xenomai: starting POSIX services.
[ 0.296357] Xenomai: starting RTDM services.
[ 0.296357] Xenomai: registered exported object RN#0 (regions)
[ 0.296357] Xenomai: starting pSOS+ services.
[ 0.305601] HugeTLB registered 4 MB page size, pre-allocated 0 pages
This is the example application:
#include <psos+/psos.h>
void task2_func(u_long a,u_long b,u_long c,u_long d)
{
while (1) {
tm_wkafter(1000);
}
}
int main(int argc, char **argv)
{
unsigned long tid;
unsigned long args[4] = {0,0,0,0};
t_create("TEST",10,160000,160000,0,&tid);
t_start(tid,0,task2_func,args);
while (1) {
sleep(100);
}
}
The command line used during compilation is:
/home/meeusr/repo/xenomai-configs/buildroot-output/staging/usr/bin/i686-unknown-linux-uclibc-gcc
-Os -pipe -Os -mtune=i686 -march=i686 -D_LARGEFILE_SOURCE
-D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64
-I/home/meeusr/repo/xenomai-configs/buildroot-output/staging/usr/include
-I/home/meeusr/repo/xenomai-configs/buildroot-output/staging/include
--sysroot=/home/meeusr/repo/xenomai-configs/buildroot-output/staging/
-isysroot /home/meeusr/repo/xenomai-configs/buildroot-output/staging
-I/home/meeusr/repo/xenomai-configs/buildroot-output/target/usr/xenomai/include
-D_GNU_SOURCE -D_REENTRANT -Wall -pipe -D__XENO__
-I/home/meeusr/repo/xenomai-configs/buildroot-output/target/usr/xenomai/include/psos+
rtprint.c -lpsos
-L/home/meeusr/repo/xenomai-configs/buildroot-output/target/usr/xenomai/lib
-lxenomai -lpthread -lpsos -Xlinker -rpath -Xlinker
/home/meeusr/repo/xenomai-configs/buildroot-output/target/usr/xenomai/lib
-lrtdk -o rtprint_ronny
When I try to run the application I get (first time):
# ./rtprint_ronny
Xenomai pSOS skin init: t_shadow() failed, status -14#
#
The second time I get
# ./rtprint_ronny
[ 145.049826] Xenomai: FAILED to register object MAIN (unknown type),
status -17
Xenomai pSOS skin init: t_shadow() failed, status -17#
#
I already read somewhere that the -14 and -17 error codes (negative values)
indicate that there is a problem in the nucleus
Can somebody tell me what I do wrong?
Best regards,
Ronny
