Well, than this feature shoulb be added to the mkimage tool. I suggest to add a directive to the configuration file (imximage.cfg), such as PADDING or something like this. > We would not have to care for the correct offset > then (which is more error prone). And it is necessary btw, to have this > offset added, when using the FSL kobs-ng tool To my knowledge: do you have the sources for this tool to better understand what it does ? I can find binaries with different version (I think 1.3 is the last), but no sources at all. I have not found if it is open source or not.
