Running I.MX7 - ARM cortex M4 automatically

Hi,

 

I have tested ARM cortex M4 in I.MX7 by using below commands. 

 

fatload mmc 0:1 0x7F8000 hello_world.bin
dcache flush
bootaux 0x7F8000

 

The application is started on the ARM Cortex-M4 core with dmesg output in the UART2 console. Now I am trying to run this Auxiliary core automatically during the boot. In the u-boot, I can see the below information related to M4 core.   

 

Output of printenv

 

loadm4image=fatload mmc ${mmcdev}:${mmcpart} 0x7F8000 ${m4image}
m4boot=run loadm4image; bootaux 0x7F8000
m4image=m4_qspi.bin

 

Though, M4 core is not launched automatically during the boot sequence. Can anyone help me out on this?

 

Thank You for support.
