For people who don't know your CPU (system? flash architecture? way to boot?) and have no real idea what's "the onenand_ipl features" might be: Do you kindly like to give some additional details about the problem, what onenand_ipl features are, why it is hard to add the new code etc. Getting a better idea about the problem would help to get a solution for this ;) If you have, some example code might help, too. Many thanks and best regards Dirk
