Could you teach the timing which starts access to Boot Device after POR is de-asserted?
OS image is stored in eMMC.
In this case, I understand that they are the following sequences.
(1)POR is de-asserted => (2)internal Boot loader start => (3)Read Boot cofig pins => (4)access start to eMMC
Is the time from (1) to (4) defined?
For example, It is 5HCLK necessity from POR_deassert to eMMC access. etc.
Your kind helps would be greatly appreciated.
