Connected Fail

lixinhua — Mon, 18 Apr 2016 11:58:18 GMT

Dear Sir ;

目标芯片是MCF5272（产品的接口如附图所示#1659），购买了P&E的BDM（参考附件）和P&E官网要求的转换器（Cable -CF-adapter）。但在运行CodeWarrior 7.2，提示“Connected Fail” , 也看不到具体失败原因！查看下载器供电和驱动正常，目标板处理器供电工作正常，目标板也确认是100% OK ! 由于P&E BDM跟我们设计的目标板不能直接连接，又参考两边的图纸自行焊接了一快转接板，自我检查线路正确，加装到Cable -CF-adapter。我的问题是：1.能否提供目标板的接口对应P&E BDM接口连接图（我不能确确定自己焊接的转接板是100%正确的）？ 2. 运行CodeWarrior 7.2时，用P&E的BDM ，需要作哪些设置，还是一定要购买P&E推荐的开发软件？

谢谢！

hello xinhua,

May I suggest you rewrite your question in English? thus NXP Codewarrior for Coldfire engineer overseas can also see it.

Best Regards,

Hello xinhua

For the hardware design of BDM interface, you may refer to the schematic of M5272 EVM board. The BDM interface design is on page 8:

http://cache.nxp.com/files/soft_dev_tools/hardware_tools/schematics/M5272C32_2.zip

In order to use Universal Multilink, you need to install CW7.2.1 and CW7.2.2 patches:

CodeWarrior Development Tools for ColdFire|NXP

And what is the OS on your PC? There is some problem to run CodeWarrior v7.2 on Windows 7-64bit OS or higher version. In addition, the firmware in your Universal Multilink may need to be reprogrammed in order to be supported by CodeWarrior v7.2.
