Overview
Description
This product is a real-time operating system (real-time OS) that is an implementation of the μITRON4.0 specification. μITRON is the predominant real-time OS for embedded systems in Japan. Its low resource requirements, outstanding real-time performance, and broad range of service calls make it very suitable for embedded systems requiring true real-time and multi-tasking capabilities.
In addition, its high degree of compatibility with the compiler package from Renesas Electronics and the configurator which automatically generates startup files will help you greatly reduce development times and get your products to market more quickly.

AI-generated Summary:
The document explains the installation process for creating a workspace with RI600/4 on RX Family RX600 Series devices. It outlines the prerequisite installations, including Renesas High-Performance Embedded Workshop (HEW), C/C++ Compiler Package, and E1/E20 Emulator Debugger. Users must verify these installations through HEW’s Tools Administration before installing RI600/4. The installation involves selecting language, agreeing to the license, choosing the destination folder, and completing setup with optional shortcuts.

AI-generated Summary:
This section explains common RTOS debugging issues such as deadlock and stack overflow. Deadlock occurs when tasks mutually wait for resources held by each other, causing them to be stuck in a waiting state. It requires four conditions: mutual exclusion, hold and wait, no preemption, and circular wait. Stack overflow happens when a task's stack size is exceeded, often due to large local variables or infinite recursion. Tools like Renesas real-time OS aware debugging and hardware break settings help identify these issues.

AI-generated Summary:
The document explains how to compute user and system stack sizes in RI600/4 programs. It distinguishes between user stacks allocated per task and a system stack for the kernel and handlers. Proper stack size allocation is critical to avoid memory waste or stack overflow. User stack size calculation involves measuring the task entry function's stack usage using tools like Call Walker, which processes stack information files generated during compilation. The document details enabling stack info output in HEW and interpreting Call Walker results to determine stack requirements.

AI-generated Summary:
The document details the specifications and usage of the M3S-TFS-Tiny filesystem library for microcontrollers in the R8C, H8/300H Tiny, and M16C/Tiny series. It supports FAT16 on media sizes from 32 MB to 1 GB, with features like multiple drive support, fixed 64-byte logic sectors, and variable file sizes allocated in blocks. The library includes type definitions, explanations of key terms such as logic sectors and drives, and provides a sample program with memory driver interfaces and error codes.

RI600V4 Real-time OS for RX Family
Functions
The RI600/4 kernel consists of the following modules. Each module is provided by functions (service calls) .
- Scheduler
Manages execution sequence of multiple tasks based on their priority levels. - Task management
Manages task status such as RUNNING, READY, WAITING or SUSPENDED. - Task-dependent synchronization
Changes task status from other task, and synchronizes tasks. - Synchronization/communication
Carries out synchronization and communication between tasks. The following function modules are available:- Semaphore
An object for exclusive control of shared devices and variables for two or more tasks. - Event flag
An object to control the execution of a task according to the AND/OR condition represented by bit pattern. - Data queue
An object to perform 1-word (32 bits) communication. - Mail box
An object to communicate an arbitrary-length message by pointer passing. - Mutex
An object to perform exclusive control, and providing support for the feature to avoid priority inversion problems. - Message buffer
An object to communicate an arbitrary-length message by copying.
- Semaphore
- Fixed length memory pool
An object to dynamically allocate/free memory of preassign fixed size. - Variable length memory pool
An object to dynamically allocate/free memory of arbitrary size. - Interrupt processing
Returns from an interrupt handler, enables/disables an interrupt for each task, and so on. - Time management
Sets system timer used by RI600/4 kernel and starts user-defined alarm handler, cyclic handler and overrun handler. - System configuration management
Reports information such as version number of RI600/4 kernel. - System state management
Modifies and refers system status. - Object reset function
Initializes the Data queue, Mail box, Message buffer, Fixed length memory pool, Variable length memory pool. This function is unique to the RI600/4 and is not defined in the μITRON4.0 specifications.
