A Simple application demo for RTEMS
- First you should locate your RTEMS BSP. For my PC it is installed in
/home/javad/ssd-workspace/rtems/output/5 - Next, the type of the target should be specified. This can be done by executing
rtems-bspsin the RTEMS kernel path. As I built it fori386, the target would bei386/pc386 - We should configure our simple demo with:
$ ./waf configure --rtems=/home/javad/ssd-workspace/rtems/output/5 --rtems-bsp=i386/pc386 The configuration result:
Setting top to : /home/javad/ssd-workspace/rtems/application/hello
