A91M55800 boot problem

Sun Apr 14, 2013 5:30 pm


I have faulty device with AT01M55800 on board which fails boot. I have checked required power and reset which seems ok. But a very low voltage(about 4mv ) 32768 Hz signal can be observed on Xin32 which is suspicious.
your help is greatly appreciated.
