can‘t start Cortex M33 demo images using imx-mkimage on iMX8ULP

[wendy-liu]

Dear all,

    My steps are as follows：

     1、Generate container image table with imx-mkimage

make SOC=iMX8ULP REV=A1 flash_dualboot

     Result boot image container is iMX8ULP/flash.bin    

     2、Write flash.bin to flexspi0 nor flash with uboot

     3、switch to low-power boot mode (sw5[8:1] = 1000 0001)

     4、 open fourth enumerated serial port(Cortex-M33’s serial console)

      But  the console print nothing!

      What's wrong with my steps?

      Thank you so much!

Regards!

Hello,

Please refer this, if you want to burn dual boot image, need to prepare four files.

The uuu_8ulp_dual.auto can be got from the demo images.
