I have a question about i.MX6D external crystal.
Is there any restrict to input sequence between external 24MHz crystal and 32kHz crystal?
(e.g. external 32kHz crystal have to start oscillation before 24MHz start it)
Actually, some custom boards didn't boot.
Then, these boards worked when remove external 32kHz crystal and when replace it to 32kHz external oscillator.
So I doubted the 32kHz crystal as root cause and checked what is different between custom boards and MCIMX6Q-SDP.
Then, the difference is oscillation sequence of 32kHz and 24MHz as attached file. (sorry, the image includes Japanese)
So I want to know whether this is root cause or not.
For your information, I have checked the resistor and capacitor values on 32kHz oscillation circuit are suitable.
And have added 2.2M ohm resistor to XTALI for ERR005777.
