IAR i.MX 8MPlus M7 boot

Hi, I'm developing with IAR the M7 core.

I installed the iar_segger_support_patch_imx8mp.zip and all seems works but there is a little problem, I can load, and run, the M7 code only if the A53 is stopped into the u-boot console

I would like to run M7 code without any code running in A53 but is not possible, I remember that I had the same problem with the i.MX 6SoloX, problem solved loaded with IAR  two JLinkScript files

iMX6SoloX_Connect_CortexM4.JLinkScript and  iMX6SoloX_Connect_CortexA9.JLinkScript

Are there the same files for A53 and M7 cores?
