[U-Boot] boot qnx image from NOR Flash

Hello,

I'd like to ask for some help regarding QNX operational system. The problem is that i don't know how to boot a QNX image situated in the NOR Flash. It boots fine form network over tftp. Neither "raw" nor "elf" image could be booted. I've tried with bootm, bootelf and go commands, but it didn't work. What should I do exactly to be able to boot a QNX image from a NOR Flash? Many Thanks in advance.
