Greetings,

I have  board  based on i.MX6 and configured  with PARALLEL NOR  (EIM) as the boot device.

XTALOSC =24 MHZ and the data width of NOR is 16.

As per RM  below are the cloks at  boot time.

My question is ,

After the  power good signal, how much time does it take to run the first instruction of a secondary boot loader (considering BT_FREQ=0)?

XTALOSC =24 MHZ, System PLL = 792

NOR  DATA Width = 16.

NOR  ADDR Width = 25.

Thanks for your heads up.
