When the nano powers up, it does many things but the 2 items that I’m interested in at the moment are the assertion of NANO_SYS_RESET_L and the detection of the camera. Is the assertion of NANO_SYS_RESET_L before or after the detection of an attached camera? If “before”, can I get an approximation regarding how much time is between the assertion and the camera detection?
Rationale: in the system that we’re building, the plan is to provide power to the camera when the NANO_SYS_RESET_L is asserted. We need to make sure that the camera is up before the camera-detection starts. One of the guys here says "I think the Nano has a PMIC that it uses to drive that signal, so I think it releases the RESET once the Nano power supplies are up, but before the Nano has finished (or probably even started) booting. " … did he get that right?
