I am not sure if the AM3517 is even on the radar, but it has > an sgx530 as well. My estimate is am3517 is wired the same way as omap34xx with a 60% chance, then 30% chance it's wired the same way as omap36xx, and then 10% chance for similar wiring to am335x.. So hopefully that leaves 0% chance for yet something different for it's wiring :) If you have a chance please give it a try. Also check the TRM for the sgx sysconfig register bits to see which of the above matches, and if 3517 has a related rstctrl register like am335x has. Regards, Tony
