True, the flashing process is successful. But avoiding those warnings would provide a better user experience. We've had customers asking for it since to them it looks like something isn't copied properly. > - I haven't had time to investigate yet.... Well the whole image is downloaded to an aligned address which is fine. But then the header is skipped which gives a non-aligned data address for the write command: http://git.denx.de/?p=u-boot.git;a=blob;f=common/image-sparse.c;hb=HEAD#l153 Here is the backtrace when that happens (not sure if it helps): http://pastebin.com/Qun8uMXq Not sure what would be the proper way to fix, copy the buffer to align it seems inefficient.
