Yes, I believe so, I atleast haven't seen the issuess with more recent TI components. The boot problems on omap3 (and 4?) were afaik a combination of boot rom issues/erratas (and therefore depending on chip revisions) and sw limitations (E.G. early xloader versions had various limitations). https://groups.google.com/forum/#!topic/beagleboard/ro5k5r4Cuq4 http://elinux.org/Panda_How_to_MLO_%26_u-boot I do have an early pandaboard somewhere that I can try to dig out and do some tests with. -- Bye, Peter Korsgaard
