Booting from SD card but running on QSPI for IMX6ULL

Hi everyone,

my application starts from SD card flashed from custom kernel coming from 4.14.78-r0.

My intention would be keep the boot from SD card but use the application ruuning from QSPI.

Is it possible to do that easily?

thanks

Fabio

Hi Fabio

seems most easy way to run m4 core from qspi using examples from

SDK2.2_iMX6ULL_WIN

Sorry Igor,

I didn't understand.

Where I have to look for? 

Absolutely I need to have the sd card for booting the board and also for the application ... but

I was thinking something like move the application on qspi to run ...

thanks

Hi Fabio

I think one can use approach described in sect.5.2 Using Manufacturing Tool attached

Getting Started with MCUXpresso SDK for i.MX 6ULL Derivatives.pdf

check for "b. QSPI XIP image".

Sorry Igor

I need also only a simple test to check the QSPI for hardware validation ...

Is it possible via unit_test?

Thanks
