I have an image built out side of QNX Momentics IDE, and I imported it to a QNX System Builder project. But I'm having 
trouble to download it to my board (Freescale ADS512101).

I've got the tftp server running on my host (my laptop) by QNX Momentics IDE, but when I kick off the downloading using 
command "tftp 200000 my_image_name" in a serial terminal, I always get "Retry count exceeded: starting again". Does this
 mean there's some network connection issue? Or I should increase the retry count limit (I didn't find out how to change
 the retry count setting)?
