Zephyr on R5/M4F

Current SoCs frequently feature heterogeneous remote processor units in asymmetric multiprocessing (AMP) setups, which may be running several Linux or other real-time OS instances. One such SoC is TDA4VM, with heterogeneous multicore support it can run multiple operating systems simultaneously. TDA4VM has Dual 64-bit Arm® Cortex®-A72 microprocessor subsystem at up to 2.0 GHz, Six Arm® Cortex®-R5F MCUs at up to 1.0 GHz, Two C66x floating point DSP, up to 1.35 GHz, 40 GFLOPS, 160 GOPS and 3D GPU PowerVR® Rogue 8XE GE8430, up to 750 MHz, 96 GFLOPS, 6 Gpix/sec. Zephyr is a small real-time operating system for connected, resource-constrained and embedded devices supporting multiple architectures. Zephyr allows for easy handling of multiple configuration options, APIs and external components, and is well suited to structured application development. Another benefit of Zephyr is that it targets some very serious protocol and standard implementations, being e.g. the first open source RTOS to introduce TSN support – by way of Antmicro’s contribution. The rising popularity of TSN in automotive and aerospace applications, and just about everywhere else, could be a very important reason to start using Zephyr in your TSN-capable product. The goal of the project is to add Zephyr RTOS support to run on Cortex R5 processor core loaded from A72 core running Linux through remoteproc and add few peripheral support (Interrupts, Gpio, UART, Timers) for TDA4VM. The Cortex R5 processor cores are built to provide deeply embedded real-time and safety-critical systems. Adding Zephyr RTOS support for R5 cores in TDA4VM will be very helpful for the Users.. Programming Languages: Assembly Programming, C.
