If it truly works with 0.4.0 and not with 1.1.4, I would speculate that 
your memory map with 1.1.4 is not compatible with your hardware... 
either your 1.1.4 image is in a different location or it is bigger.

Check your image sizes and locations (objdump for elf, less (the program 
;-) for S-record files, xxd and some luck if all you have is a 
VisionProbe binary lump).
