IMX93 ethosu_apps_rpmsg例程使用咨询

现在需要在imx93的m33核通过lpspi3驱动一块lcd屏幕,在ethosu_app_rpmsg中添加了spi相关的驱动后,可以通过编译,但是在执行时会触发段错误,代码在加载时没有运行到相关的信息打印阶段就触发了错误。同时我们基于ethosu_app_rpmsg例程移植测试uboot阶段加载m33固件,出现报错,log如附件log1所示,基于ethosu_app_rpmsg例程移植测试在内核阶段加载m33固件,同样出现报错,不过错误log不一样,log信息如附件log2所示,SDK版本是6.1.55,基于官方imx93 evk开发板测试,ethosu_apps_rpmsg例程是做什么的,看没有相关的readme.md,是不是有什么前置条件?

Hello @chenyuansen 

 

I hope you are doing very well.

The Ethos-U65 NPU is integrated with NXP i.MX 93 processor and works in concert with the Cortex-M core and on-chip SRAM of the SoC.

You can find all of these information in the i.MX Machine Learning User's Guide chapter 6.2.

 

There is explained how Ethos-U works.

 

Best regards,

Salas.
