Re: [ts-7000] TS7200 Real Time Programming

[Ronald Gomes <>]

Hi,

If you are able to run all the RTAI kernel and user space examples, then you succeed on the RTAI installation step.

However, to build RTAI application you will also need the rt-kernel header files. You can patch the ts8 kernel with the Adeos patch provided at ftp://oz.embeddedarm.com/rt/arm-ts8/ and build it. All the needed information for this step is provided by the "Getting Started with RTAI" guide, developper section.

After building the rt-kernel, use the new linux-include dir when compiling your RTAI application, for example:

gcc -Wall -I/usr/src/linux-2.4.26-ts8-rt/include -I/usr/realtime/include -c test.c -o test.o

Anyway, I will place a tarball with the rt-kernel header files at the ftp server soon... I let you know when done.

Regards,
Ronald.

Hi,

I am trying to setup my ARM board to execute some control code every 1ms so I decied to use the RTAI kernel provided. I have been able to install the rt kernel load the modules and run the test programs successfully. Where I am having a problem is trying to compile a program which uses the header

#include <rtai_lxrt.h>

This header includes others which eventually always comes down to missing a file.
I have tried setting up the system using TS8 and TS9 files sets have the same issue.

gcc -Wall -I /usr/realtime/include -c test.c -o test.o
In file included from
 /usr/realtime/include/asm/rtai_hal.h:116,
                 from /usr/realtime/include/asm/rtai.h:42,
                 from /usr/realtime/include/rtai.h:26,
                 from /usr/realtime/include/rtai_sched.h:22,
                 from /usr/realtime/include/rtai_lxrt.h:69,
                 from test.c:12:
/usr/realtime/include/asm-arm/arch/rtai_arch.h:28: asm/arch/ep93xx_tsc.h: No such file or directory

I have looked in the TS9 and TS8 files and niether tar files supplied contain this file.

ls usr/realtime/include/asm/arch/
 -l

-rw-r--r--  1 cliff users 1994 Aug 15 17:18 rtai_timer.h

I've even tried downloading the RTAI-3.2 tar file and it is not contained in there.
Am I doing somthing wrong?

Thank you,
Cliff Blackburn
