RZ/N2L Industrial Network SoM Kit

AI-generated Summary: The Serial Host interface library enables shared memory access between an external SPI master and the RZ/N2L microcontroller, facilitating direct access to internal resources such as System SRAM and mailbox/semaphore registers. It supports exclusive control and interrupt signaling between the internal Cortex-R52 CPU and the external host CPU. The library manages read/write operations to shared memory and CPU notifications. The document details system configuration examples, operation conditions, peripheral settings, API functions, and sample applications demonstrating the use of the shared memory interface.

AI-generated Summary: EtherCAT slave functionalities on the Renesas RZ/N2L platform run on a single core using EtherCAT Slave Stack Code generated by the SSC Tool. The stack supports EtherCAT State Machine, mailbox protocols like CoE, synchronization modes including Free Run, Sync Manager, and DC synchronization, and CiA402 drive profiles (csp and csv modes). Setup requires the RZ/N2L Industrial Network SOM Kit, IAR Embedded Workbench with patch, e² studio, FSP Smart Configurator, and TwinCAT3 for master configuration. The document guides through hardware setup, stack code generation, sample application execution, and interaction with TwinCAT3 for device scanning, EEPROM updates, and drive profile checks.

AI-generated Summary: Setup procedures for the RZ/N2L port of EtherNet/IP OpENer software enable communication with CODESYS PLCs using open-source components like FreeRTOS and lwIP. The sample program supports Exclusive and Input Only connections, implementing key CIP object classes such as Identity, Assembly, and Connection Manager. Development requires the RZ/N2L Industrial Network SOM Kit, IAR Embedded Workbench, e2 studio, and CODESYS v3.5.15.10. Detailed instructions cover hardware setup, IP configuration, source code generation, building, debugging, and network operation verification. The package includes OpENer source code under an open-source license and references for RZ/N2L hardware and software resources.

AI-generated Summary: The Modbus TCP slave function enables communication using the Modbus protocol stack on the Renesas RZ/N2L Industrial Network SOM Kit. It supports nine Modbus function codes including reading and writing coils and registers. The document details project setup requirements, including compatible boards, IDEs such as Embedded Workbench for ARM and e² studio, and necessary patches. It also covers steps for configuring the board, setting IP addresses, building and debugging sample projects, and running demonstrations. Additional appendices provide DHCP mode setup, API references, and FSP configuration for the VSC8531 Ethernet PHY.
