准备工作

在使用GR5515 SK板前,建议完成以下准备工作。

  • 硬件准备
名称 描述
数据线 Micro-USB 2.0数据线
开发板 GR5515 Starter Kit开发板
  • 软件准备
名称 描述
操作系统 Windows 7操作系统及以上版本或者Ubuntu 18.04 LTS版本
串口助手 可打印串口日志的串口终端
GProgrammer 固件下载工具 点击下载
  • 供电和连接

如下图所示是GR5515 Starter Kit开发板的装配图。

GR5515 Starter Kit开发板装配图

在使用GR5515 SK板之前,需按以下步骤完成供电和连接设置:

  1. 使用Micro USB 2.0线连接GR5515 SK板和PC。Mirco USB用于供电以及通过J-Link进行编程。
  2. 将电源开关S6切换到右端,设置为SK板LDO供电;将S6切换到左端,设置为锂电池供电。
  3. 将电源开关S5切换到右端ON的位置,打开电源。
  4. D102开始闪烁表示PC开始检测J-Link接口。检测成功后,D102不再闪烁,变成常亮。
  5. D102常亮后,打开PC的设备管理器,检查设备管理器 > 端口(COM和LPT)列表中是否有JLINK。若出现,则供电和连接设置完成,可对GR551x进行编程下载;若未正确检测到JLINK设备,则需要检查是否正确安装了JLINK驱动,可以尝试重新安装最新版本的JLINK驱动。

提示:

  1. 安装GProgrammer会自动安装JLINK驱动,如果PC未安装JLINK驱动,请先下载安装GProgrammer

  2. 开发板通过Mirco USB连接到PC后,会在设备管理器中"端口(COM和LPT)"列表中出现一个"JLink CDC UART Port(COMX)"串口号,串口助手需使用该串口号观察开机log信息。
