R-CAR Spider S4 (ARM64)
#######################

Overview
********
R-Car S4 enables to launch Car Server/CoGW with high performance, high-speed networking,
high security and high functional safety levels that are required as E/E architectures
evolve into domains and zones. The R-Car S4 solution allows designers to re-use up to 88
percent of software code developed for 3rd generation R-Car SoCs and RH850 MCU applications.
The software package supports the real-time cores with various drivers and basic software
such as Linux BSP and hypervisors.

Hardware
********
The R-Car S4 includes:

* eight 1.2GHz Arm Cortex-A55 cores, 2 cores x 4 clusters;
* 1.0 GHz Arm Cortex-R52 core (hardware Lock step is supported);
* two 400MHz G4MH cores (hardware Lock step is supported);
* memory controller for LPDDR4X-3200 with 32bit bus (16bit x 1ch + 16bit x 1ch) with ECC;
* SD card host interface / eMMC;
* UFS 3.0 x 1 channel;
* PCI Express Gen4.0 interface (Dual lane x 2ch);
* ICUMX;
* ICUMH;
* SHIP-S x 3 channels;
* AES Accerator x 8 channels;
* CAN FD interface x 16 channels;
* R-Switch2 (Ether);
* 100base EtherAVB x 1 channel;
* Gbit-EtherTSN x 3 channels;
* 1 unit FlexRay (A,B 2ch) interface.

Supported Features

Programming and Debugging
*************************

The onboard flash is not supported by Zephyr at this time. However, it is possible to
load the Zephyr binary using U-Boot commands.

One of the ways to load Zephyr is shown below.

.. code-block:: console

   tftp 0x48000000 <tftp_server_path/zephyr.bin>
   booti 0x48000000

Here is an example for the :ref:`hello_world` application.

.. zephyr-app-commands::
   :zephyr-app: samples/hello_world
   :board: rcar_spider_s4/r8a779f0/a55
   :goals: build

개요

R-Car S4는 E/E architecture가 domain과 zone 구조로 발전하면서 필요한 고성능, 고속 networking, 높은 security와 functional safety를 갖춘 Car Server/Communication Gateway(CoGW)를 구현합니다. Designer는 3세대 R-Car SoC 및 RH850 MCU application용으로 개발한 software code의 최대 88%를 재사용할 수 있습니다. Software package는 여러 driver와 Linux BSP, hypervisor 같은 basic software로 real-time core를 지원합니다.

하드웨어

R-Car S4에는 다음 기능이 포함됩니다.

1.2 GHz Arm Cortex-A55 core 8개(2 core × 4 cluster)
Hardware lockstep을 지원하는 1.0 GHz Arm Cortex-R52 core
Hardware lockstep을 지원하는 400 MHz G4MH core 2개
ECC를 갖춘 32-bit bus(16-bit 1 channel + 16-bit 1 channel) LPDDR4X-3200 memory controller
SD card host interface / eMMC
UFS 3.0 1 channel
PCI Express Gen4.0 interface(dual-lane × 2 channel)
ICUMX
ICUMH
SHIP-S 3 channel
AES accelerator 8 channel
CAN FD interface 16 channel
R-Switch2(Ether)
100BASE EtherAVB 1 channel
Gigabit Ethernet TSN 3 channel
FlexRay 1 unit(A/B 2 channel) interface

지원 기능

Renesas rcar_spider_s4/r8a779f0/a55 board configuration은 다음 hardware feature를 지원합니다.

인터페이스	드라이버/컴포넌트	지원 수준
`PINCTRL`	`pinctrl`
`CLOCK`	`clock_control`
`UART`	`serial`	`interrupt-driven / polling`

그 밖의 hardware feature는 아직 이 보드에서 활성화되지 않았습니다.

프로그래밍과 디버깅

현재 Zephyr는 on-board flash를 지원하지 않지만 U-Boot command로 Zephyr binary를 load할 수 있습니다. 한 가지 방법은 다음과 같습니다.

tftp 0x48000000 <tftp_server_path/zephyr.bin>
booti 0x48000000

다음은 hello_world application을 build하는 예입니다.

west build -b rcar_spider_s4/r8a779f0/a55 samples/hello_world
