I have a standalone ls1021a, eMMC, a Atemega328P chipset on the board and a JTAG interface. I want to bring the board up to initiates the power-on reset flow. I am trying to implement the CPLD logic into C using Atemega328P to achieve the board initialization stage.
Does any one know how many signals do I need to consider which I need to trigger them in the right sequence?
According to the QorIQ LA1021A Reference Manual.
I also have a question specifically during the POR sequence,
Do I have to give a signal to the cfg_eng_use0 or once the POR starts everything will be handled by itself.
