IMX93 M33 add LPSPI3 initialize code in ethosu_app_rpmsg

lzxxxx — Fri, 25 Apr 2025 08:02:07 GMT

Hello,

I'm using both M33 and A55 (imx93). I want to drive a lcd screen from MCU ( LPSPI3) in project ethosu_app_rpmsg.

When i compile this project and move the output elf file to A55(imx93) to execute, unexcepted error occurred:
