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
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
