I am trying to run openamp_rsc_table example for imx95_evk board. On running west build command, zephyr.elf is generated. However, when I am running this elf file using remoteproc with Linux running on my A55 core, I don't see the messages sent between A Core and M Core. My M7 console only shows Zephyr Booting message and then halts. I have used yocto to generate Linux image for A55.
Hi Daniel, I tried building this example. However, SAMPLE_RPMSG_CLIENT configuration is not defined. Therefore, the module: rpmsg_client_sample.ko is not generated. While the application is building and successfully generating zephyr.elf, on running this elf on A Core (linux), it is not executing beyond Zephyr Booting message.
Hi Daniel, I had to add rpmsg_client_sample.c separately to linux build to generate an imx-image-full image. After copying zephyr_openamp_rsc_table.bin file and generating flash.bin, I booted the board. Post this my module is loaded but not in use. Moreover, my remoteproc's state is attached and I am unable to change the state.
