I have a UCD90160 on the circuit card I've been developing on. I have done many writes and stores on this device and today it stopped sequencing without the Fusion GUI running. If I disconnect the USB adapter on power-on, my power rails do not enable. Once I open the Fusion GUI , as soon as the Fusion Digital Power Design scans for USB device, the UCD90160 finally starts a power-on sequence.
Have I somehow corrupted the internal firmware? I have run an erase and reprogram on the device, but it still behaves the same
