I.MX93，If M33 is running , then it fails to start the Linux kernel..

[adaihua13]

    Hello, I'm realizing I. MX93 development board A55 core (Linux) and M33 core (bare machine) run at the same time encountered difficulties.

     Here's how it works: First，Uboot starts from the SD card, stays in the UBOOT stage, and starts the M33 core with the following command：
1、tftp 0xd0000000 sdk20-app.bin
2、cp.b 0xd0000000 0x201e0000 0x20000
3、bootaux 0x1ffe0000
      After the above three steps, the M33 core is up and running. I then proceeded to boot the Linux kernel on A55 using the following command：
1、setenv bootcmd "tftp 0x80400000 Image; tftp 0x83000000 imx93-11x11-evk-rpmsg.dtb; booti 0x80400000 - 0x83000000"
2、run bootcmd

      After the above 2 steps, started the Linux kernel, but failed to boot, has been stuck in the following stag：

Hello @adaihua13 

Have you tried with boot command?

After of saving you environment with your fdtfile as imx93-11x11-evk-rpmsg.dtb, please try to boot with boot command.

Best regards.
