Dear Vladimir,

I use ELDK with RTAI patch installed on MPC850. I attempted writing a regular Linux driver (independent from RTAI calls) using down()/up() functions. When I attempted to load insmod to install my module I received error "unresolved symbols" for these calls.

Bad compiler options? Check for missing "-O"... Missing header file in your source code? Check for "include/asm-ppc/semaphore.h" ...

I assume some module should be added ELDK configuration. But, may be, the problem is in RTAI extension?

And what has all this to do with U-Boot?
