First data fetch by i.MX8QM SCU from the flexSPI FLASH after a power-on reset

[ToarteFretter]

Hi,

Is it somewhere specified/documented when you let the i.MX8QM boot from a connected flexSPI FLASH, when the SCU will make the first access to the FLASH measured from the power-on reset de-assertion of the i.MX8QM?

We want to check if our connected FLASH will be ready to be accessed, once its power-on reset (which is the same that goes to the i.MX8QM) is de-asserted, at the moment the i.MX wants to perform the first access...

Thanks!

Kind regards.
