RH850/F1K and F1Kx FreeRTOS Port with CC-RH Compiler

Introduction

This repository contains the port of FreeRTOS for Renesas RH850/F1K and F1Kx microcontrollers using the CC-RH compiler. The following sections provide instructions on how to use this port, a link to the test project, and other relevant information.

Prerequisites

  • Compiler: CC-RH
  • FreeRTOS version 11.1.0
Device FPU SMP
F1K Yes No
F1KM-S1 Yes No
F1KM-S2 Yes No
F1KM-S4 Yes No
F1KH-D8 Yes Yes

Link to Test Project

The test project can be found here (RH850_F1Kx_CCRH). This project contains example tasks and configurations to help you get started with FreeRTOS on the RH850/F1K and F1Kx.

Note

  1. Configure IPIR Interrupt: Ensure that the bit specifying the destination for binding (requesting) an interrupt is enabled (e.g: IBDxxx register of F1KH-D8) (1)
  2. Channel 0 and address 0xFFFEEC00 are used as default configuration for configIPIR_CHANNEL and configEXCLUSIVE_ADDRESS, in case of resource confliction other channel/address can be used. (2)
  3. The minimal stack size (configMINIMAL_STACK_SIZE) must be included the reserved memory for nested interrupt. This formula can be referred: (task_context_size) * (2 + configMAX_INT_NESTING) + Stack_depth_of_taskcode In which, task_context_size is calculated as 36*4bytes = 144bytes (when FPU enabled) or 34*4bytes = 136 (when FPU disabled), configMAX_INT_NESTING is 02 as default (Note that a value of 0 is not allowed).
  4. configTIMER_PRESCALE: This value is required in order to correctly configure clock for CPUCLK_L. Refer to Hardware Manual at Table 44.22 for option byte: If the user sets the option byte CKDIVMD to 1, then configTIMER_PRESCALE = 4. Otherwise, if CKDIVMD is set to 0, then configTIMER_PRESCALE = 2.

(1) This is applicable for F1KH-D8 with SMP only.

(2) This is optional and applicable for SMP only.
