• 前提条件

1. jlink 调试器
2. OK6410A 板子中 DBGSEL 接地
3. JLink_Windows
4. https://github.com/lisider/ok6410-rawcode/tree/master/bin 中的 1led.bin

过程

连接硬件

怎么连接就不用说了

打开软件

D:\ProgramFiles\ProgramFilesForSW\SEGGER\JLink\JLink.exe

操作后的现象为led4一直闪烁

操作流程如下
Type "connect" to establish a target connection, '?' for help
J-Link>connect
Please specify device / core. <Default>: ARM11
Type '?' for selection dialog
Device>
Please specify target interface:
  J) JTAG (Default)
TIF>
Device position in JTAG chain (IRPre,DRPre) <Default>: -1,-1 => Auto-detect
JTAGConf>
Specify target interface speed [kHz]. <Default>: 4000 kHz
Speed>
Device "ARM11" selected.


Connecting to target via JTAG
TotalIRLen = 9, IRPrint = 0x0011
