zephyr: samples/subsys/openamp_rsc_table on an STMH7 based board - libopen_amp.a(remoteproc_virtio.c.obj): in function `metal_io_read': build/modules/libmetal/libmetal/lib/include/metal/io.h:252: undefined reference to `__atomic_load_8'

by murali.karicheri＠sandc.com

Hi Experts, I have also posted this to zephyr dev mailing list and thought to add it here as well as it is related to OpenAMP. I tried it in v3.4.x version of Zephyr before the final v3.4.0 release. I am able to get the OpenAMP Bare-metal sample application work for core-to-core messaging using the STM32CubeIDE. We are using Zephyr in our project that interfaces with Bare-metal. The OpenAMP master runs on Bare-metal and it uses resource table. So I am working to enable the samples/subsys/openamp_rsc_table. I am able to build this sample for another STM32 board as west -v build -p always -b stm32mp157c_dk2 samples/subsys/ipc/openamp_rsc_table I have added the overlay and conf required to my project files and trying to build the sample and get the below linker error. As my target is also M4 on STM32H755 SoC, I believe I am missing some change to allow the metal_io_read() to be resolved to a proper library function. Some has suggested using set(CMAKE_CXX_LINK_FLAGS "${CMAKE_CXX_LINK_FLAGS} -latomic") per https://github.com/alexa/avs-device-sdk/issues/1404 I have tried to add it to the lib/openamp CMakeLists.txt but didn't help. Since this sample builds fine for stm32mp157c_dk2 , some build flag missing for my STM32H755 SoC??? Any help on this will be appreciated.

RPMsg in U-Boot Proof of concept Patch v1

by Shah, Tanmay

Hello All, RPMsg in U-Boot is under development. First proof of concept patch v1 was sent to upstream mailing list as RFC patch here: http://patchwork.ozlabs.org/project/uboot/list/?series=365 Here is the video of demo of RPMsg framework introduced in above patch series: https://www.youtube.com/watch?v=PxGNR_FYGt8 This document explains patch series and motivation to introduce RPMsg in U-Boot and future work that needs to be done: https://drive.google.com/file/d/1Bjtzj58klMPVuWEtRK89oyem7_Hdajn8/view?usp=… This patch series is very basic implementation of virtio based RPMsg framework referenced from the Linux kernel. For now, U-Boot is communicating with remote processor over fix hard-coded endpoint. More advance features such as name-service, multiple endpoint support etc.. will be added in coming revisions of this patch series. Meanwhile, please feel free to review existing work and provide review comments and any other suggestions. Thanks, Tanmay Hello All, RPMsg in U-Boot is under development.
