If you passed the build, then the next step is to create a bootable image (SD or CF card). On a PC that is unfortunately a little complicated. You can look at e.g. board/ts/ts5x00/ for an example. Next, you'll probably want to make a custom kernel configuration because the i386_defconfig is pretty bloated. So do a 'make linux-menuconfig' and remove all the drivers you don't need. Finally, to save all that configuration, you can create a board/ directory and a defconfig. Look at the BR2_EXTERNAL explanation in the manual for suggestions on how to approach that. > > Can you give me any pointers? > > > > ?

I haven't used RTAI myself, but I thought it's Kconfig was merged with the kernel's. Hm, looking at RTAI's README, it turns out that I was wrong... Well, currently we only support the automatic configuration of RTAI, not the interactive configuration. Patches to improve that are welcome. Regards, Arnout > > Thanks for reading.
