RTP project

[chinnap...@gmail.com]

hi,

How to connect a target server to the target for an RTP project.
please send me the details of creation of RTP project.

here what is the target.
is it IPaddress of system or simulator name (likevxsim8).

Thanks

hi ..,

Iam creating RTP project on vxWorks workbench-2.6.
but it doesn't spawn a process. rtpSpawn returns -1.

I follow the procedure as below:

1. vxworks image project was created. I included the cpp components &
RTP process components which r in the OS components.
2. vxworks ROMFS project was created In the filesystem romfs I
created a new folder bin.
3. vxworks RTP project was created. In this project, i import the my
rtpSpwan file.
4. RTP project was included to ROMFS project and ROMFS project was
included to
IMAGE project.
5. Build the project.
6. I connected to simulator. Here i changed the custom simulation path
to vxworks path.
D:\kalworkspace\rtpImage\default\vxWorks.
7. In the simulator window I gave
->cd "/romfs/bin".
8. ->rtpSp "rtpSp11.vxe"
value = 272447072 = 0x103d3660 = '`'
-> AA - Hai
RTP task not Spawned
All the best for next trail

If anybody know the problem here plz help me.

My code is...

#include <stdio.h>
#include <rtpLibCommon.h> //kal

int main (void)
{
const char *argv[]= {"D:/kalworkspace/rtpSp11/SIMPENTIUMdiab_RTP/
rtpSp11/Debug/rtpSp11.vxe", NULL};
const char *envp[]=
{"HEAP_INITIAL_SIZE=0x20000","HEAP_MAX_SIZE=0x100000",NULL};
int rTP;

printf("AA - Hai\n");
rTP = (int) rtpSpawn (argv[0], argv, envp, 100, 0x10000, 0, 0);
//rTP = (int) rtpSpawn ("welcome.out", argv, envp, 100, 0x10000, 0,
0);
if (rTP == -1)
{
printf ("RTP task not Spawned \nAll the best for next trail\n");
}
return 0;
}

Regards
chinni.

Hi Chinni,

You do not say what the errno is after rtpSpawn() returned on error
but I think it is very likely that the problem is with the path to
your executable. I bet that the path "D:/kalworkspace/rtpSp11/
SIMPENTIUMdiab_RTP/rtpSp11/Debug/rtpSp11.vxe" does not mean anything
for your VxWorks target. To verify this, simply try to open this file
from the target shell (in C interpreter mode): open "D:/kalworkspace/
rtpSp11/SIMPENTIUMdiab_RTP/rtpSp11/Debug/rtpSp11.vxe", 0

I think this will fail. What you must use is a path that is meaningful
for VxWorks, such as /romfs/bin/rtpSp11.vxe (BTW, you realize that,
when this works, you are going to recursively launch rtpSp11.vxe,
right?).

Hope this helps,

hi..,

error no is -1.

Actually this is the returned status and it simply indicates that an
error happened (-1 means ERROR, 0 means OK). The error number is
obtained with the errnoGet() API. To display the errno is a clearer
format use the printErrno() API: printErrno (errnoGet());

Cheers,

hi ..,

Eventhough I included vxWorks.h, I got some errors in some system
header files.
To get error I included the header files as follows.

#include <vxWorks.h>
#include <stdio.h>
#include <rtpLibCommon.h>
#include <errnoLib.h>
#include <usrLib.h>

int main (void)
{
const char *argv[] ={"D:/kalworkspace/romfsproject/Contents/bin/
rtpSp11.vxe ", NULL};

const char *envp[] =
{"HEAP_INITIAL_SIZE=0x20000","HEAP_MAX_SIZE=0x100000",NULL};
int rTP;

printf("AA - Hai\n");

rTP = (int) rtpSpawn(argv[0], argv, envp, 100, 0x10000, 0, 0);
printErrno(errnoGet());

My mistake. The printErrno() API is not available for RTPs. All you
can do is get the error number and simply print it out. Then use
printErrno() from the target shell and pass it the error number to get
the error string. Note that you want to know the error number only if
rtpSpawn() returned ERROR. Regarding the header files, usrLib.h does
not exist for RTPs and you probably want to use rtpLib.h instead of
rtpLibCommon.h (rtpLib.h includes rtpLibCommon.h).
