This change is made because the paragraph contains the Wiki link that provides valuable information about libmetal internals, including a detailed section titled "OpenAMP Overview". It also addresses multiple format issues, including missing or duplicate spaces in the text, and corrects the line length to match the format used in README.md.

Open-AMP compatibility question

by murali.karicheri＠sandc.com

Hi Erwan, Arnaud, et all I am using the Open-AMP ping pong example available in STM32CubeMX/IDE on a STM32H7 SoC. The example (not sure if it it is the same version) is at https://github.com/STMicroelectronics/STM32CubeH7/tree/master/Projects/STM3… It is a Bare-metal example. I am trying find out which example in Zephyr can interface with this example. Currently I am using https://github.com/zephyrproject-rtos/zephyr/blob/main/samples/subsys/ipc/o… since it uses resource table as in the PingPong Bare-metal example. But as you know the open-amp package used in Zephyr side is very new (I am using Zephyr 3.4.0). I have made couple of changes listed below to work with the PingPong example 1. resource_table in linker file to use the SRAM4 on STM32H7 SoC that I am using 2. I had to define CONFIG_RAM_CONSOLE=y since without it, the shared memory resource table offsets are different as seen by the Bare-metal side. 3. The PingPong application is using name service. So I have updated Zephyr side to use name service. 4. Remove tty application. Modify the Client application to receive a 4 byte data, increment and send it back to Master With these changes, I can see the NS message sent out by CM4 running Zephyr. But my CM7 Bare-metal application doesn't see the message. So the first question is if Open-AMP/Shared memory structs are compatible? Other piece of information is Zephyr runs on CM4 and Bare-metal on CM7. On my debug, I found that the vring struct in memory has len = 0 instead of 100. Not sure where that goes wrong. Still debugging

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.
