Zephyr for ARM A53
Sandeep Kulkarni <skulkarni@...>
This is Sandeep from Maxlinear Technologies.
We are building a solution using ARM A53 – Wherein we plan to run RTOS on a couple of cores for time critical functions and we also need openAMP support.
Currently we are exploring the options – FreeRTOS, Zephyr, Threadx etc
Zephyr seems to support most of what we need in-terms of features/functionality, but I don’t find much information for Zephyr with A53 on web, only thing I see is the QEMU support.
So need your guidance on this topic.

Hello all,Zephyr has support for multiple ARMv8 based SoCs/boards. Take a look at:
There is also an ongoing PR to support NXP IMX8M SoC that has ARM Cortex A53.
* Has anyone tried Zephyr on A53 hardware ? Rpi or any other platforms?Support for ARM64 is still new compared to ARM32 in Zephyr but if you find
something is missing or broken, let us know :)
* How is the community support for this?There is some interest but it is still picking up pace.
* OpenAMP b/n Zephyr and Zephyr on A53This one works pretty well and I've tested it on STM32MP platform.
* OpenAMP b/n Linux and Zephyr on A53This should also work but I haven't tested personally.
