我们先来看看Pro的特性:
1)Fully compatible to J-Līnk ARM?? 全兼容J-Līnk ARM
目前看起来Pro跟V7支持的特性一模一样:特性字都为0xBF7BFF39
2)Ethernet interface? 以太网接口,100M,我试下来全双工不成功,半双工OK
3)USB 2.0 interface 就是把USB的器件描述符改了
4)Any ARM?7/9/11, Cortex?-M3 core supported, including thumb mode 老特性
5)More memory for future firmware extensions (ARM11, X-Scale, Cortex R4, Cortex A8)?
CPU由AT91SAM7S64改为AT91SAM7X256,RAM和Flash都大了,当然爽咯
6)Additional LEDs for power and RESET indication
增加了5V输出指示灯和目标板复位指示的LED,但实际上,Pro有5个可控的LED指示灯
7)Comes with web interface for easy TCP/IP configuration (built-in webserver)? Web服务器,可感觉没啥用
8)Built-in GDB Server (planned to be implemented in the near future)? 老特性
9)Serial Wire Debug (SWD) supported 老特性
10)Serial Wire Viewer (SWV) supported 老特性
11)Automatic core recognition 自动识别Core,但有Bug
12)Maximum JTAG speed 12 MHz? 这个没办法了,ARM7就这速度了
13)Download speed up to 720 Kbytes/second * (higher download speeds will be available in the near future)? 老特性
14)DCC speed up to 800 Kbytes/second *? 这个好像没试出来。。。
15)Seamless integration into the IAR Embedded Workbench? IDE? 这也算特性?
16)Powered through USB or power supply which comes with J-Līnk ARM Pro 这个很重要!USB供电!或外接直流电源供电
17)Support for adaptive clocking? 老特性
18)All JTAG signals can be monitored, target voltage can be measured? 老特性
19)Support for multiple devices? 老特性
20)Fully plug and play compatible? 一片74ALVC164245也能算PNP?
21)Standard 20-pin JTAG connector? 这也算特性?
22)Wide target voltage range: 1.2V - 3.3V, 5V tolerant? 5V要外接转接板的吧!!!
23)USB and 20-pin ribbon cable included? 这也算特性?明明就是装箱清单嘛。。。
24)Memory viewer (J-Mem) included? 老特性
25)Comes with licenses for: J-Līnk ARM RDI, J-Līnk ARM FlashBP, J-Līnk ARM FlashDL, J-Līnk ARM GDB Server, J-Flash ARM? 花钱呗。。。
26)Software Developer Kit (SDK) available? 花钱呗。。
27)Embedded Trace Buffer (ETB) support??这个有待研究
28)Adapter for 5V JTAG targets available? 看。。又要花钱
29)14-pin JTAG adapter available? 还是要花钱
30)Galvanic isolation from host system via Ethernet??通过网络变压器隔离,很好的特性
31)Optical isolation adapter available? 花钱。。。
先看几张靓图?
