芯驰 D9 系列处理器集成了 ARM@Cortex-A55 高性能 CPU 和 ARM@Cortex-R5 实时CPU,含有 3D GPU, H.264 视频编解码器。此外, D9 处理器还集成高速 PCIE3.0 接口，高速USB3.0 接口，千兆以太网, CAN-FD，UART，SPI 等丰富的外设接口。

丰富接口：

上电BOOT可以选择多种启动方式

USB转TTL 接口注意：

开发板系统框图：什么接口应有尽有

感觉跟Jetson TX2类似提供内置的Cortex-R5微控制器.双系统保证多任务和实时性：

开发板接入12V电源;

PUTTy

PUTTY debug 启动测试：

基础命令测试;
