You have to configure the number of each type of RTEMS object<br>
you want. You didn't configure any semaphores and probably<br>
didn't link in the semaphore manager either.<br>
<br>
But the bigger question is.. is Ray using the termios console<br>
driver? I thought he was only using printk() and avoiding the<br>
full featured console device driver and the termios subsystem<br>
entirely.<br>

When it works, I would like to see another BSP merged.<br>
If the hardware is close enough, you might be able to<br>
share a BSP and use a "variant" to change compile time<br>
options.<br>
