LXRT-HOWTO

This section gives a step by step example on how LXRT could be used with mca2.

Compiling

Installing

  • Install your kernel/modules
  • boot your rtai-enabled system
  • Copy the compiled rtai modules (rtai_hal.o/ko, rtai_lxrt.o/ko, rtai_sem.o/ko and rtai_serial.o/ko) and the mca module (mca_lxrt_extension.o/ko) to your module directory

Note: if you copy all compiled rtai modules into the kernel module directory make sure to set the link rtai_ksched.MOD_EXT to rtai_lxrt.MOD_EXT to be sure the correct scheduler is taken on modprobe.
  • Load kernel modules (easiest modprobe way)

  • Load kernel modules (step by step insmod way)
If you have an adeos kernel with adeos compiled as module, first you need to insmod that

In all cases you then have to insmod the following

  • If using the rtai_serial driver in your MCA-program you also have to insmod that module:

Or with individual configuration parameters e.g.:

Testing

  • Test it

Call time_test twice with --no-lxrt and compare the summarized measured time values.
