Introduction

note: KL520 SDK v1.6.x starts to support Kneron PLUS

1. Requirements

Hardware:

Board with KL520 chip, like 520 dongle, 96board, m.2 board

(For applications with camera) Kneron KL520 series AI SoC Development Kit

Software:

licensed software: ARM Keil MDK

ARM Keil/MDK docs

2. File Structure

The whole SDK package is composed of device firmware, the folder design is described in this section.

3. Flash_Management

Flash Programming by UART, JLink.

4. SoC Peripheral Drivers

KL520 also provides some simple examples to show how to use basic peripherals such as, I2C, PWM, DMA, GPIO... User can find them from sdkexamples folder.

There is also a PDF file to briefly describe the peripheral APIs. Please download it from the following link: KL520_Peripheral_Driver_APIs.pdf
