OTA Example

Introduction

This example demonstrates the basic process of writing a kdimg image file to an OTA device in blocks.

Source location: src/rtsmart/examples/peripheral/ota/test_ota.c

Example Behavior

• Default image path: /data/ota_test.kdimg

• The image path can be overridden via the command line

• The image is read in a loop with a 64KB block size and written by calling k230_ota_update()

• After the write is complete, resources are released and the program exits

Key Interfaces

• k230_ota_create()

• k230_ota_update()

• k230_ota_destroy()

Build and Run

cd src/rtsmart/examples/peripheral/ota
make

Run:

./test_ota [image_path]

Examples:

./test_ota
./test_ota /sdcard/update.kdimg

Notes

1. The example itself is not responsible for network download, signature verification, or version policy; these should be handled in the upper-layer flow.

2. Please avoid power loss during the OTA write process.

Tip

For OTA interfaces and the recommended calling sequence, please refer to the OTA API Documentation.
