刚开始用ulink发现驱动始终安装不上,网上搜索n久未果,罢也!后面选择jlink发现问题多多,但是出现以下数据仿佛看到希望,毕竟可以读到内核的数据 ARM7TDMI-S Core 电压 3.332V
SEGGER J-Link Commander V4.34 (? for help)
Compiled Aug 26 2011 18:24:47
DLL version V4.34, compiled Aug 26 2011 18:24:32
Firmware: J-Link ARM V8 compiled Jan 31 2018 18:34:52
Hardware: V8.00
S/N: 20080643
Feature(s): RDI,FlashDL,FlashBP,JFlash,GDBFull
VTarget = 3.332V
Info: TotalIRLen = 4, IRPrint = 0x01
Found 1 JTAG device, Total IRLen = 4:
#0 Id: 0x4F1F0F0F, IRLen: 04, IRPrint: 0x1, ARM7TDMI-S Core
Found ARM with core Id 0x4F1F0F0F (ARM7)
ETM V1.2: 1 pairs addr.comp, 0 data comp, 4 MM decs, 1 counters
JTAG speed: 100 kHz

继续探索:
check blank verify 等检查会都会出现问题,成功次数只是偶尔!于是想可能jlink是驱动不稳定问题!又开始网上搜索进入各大论坛网站,终于找到了jlink4,34版本驱动!发现问题依然不稳定.....以当年的脾气早就火了!但还会慢慢摸索终于找到问题,默认仿真速率是1000k,改为50k的时候不稳定点现象明显好转!后面改为20k基本百发百中.....
