The CodeWarrior Tap simulator is unable to recognize

Zhoute — Wed, 23 Jul 2025 01:50:18 GMT

I encountered the following problems when debugging the lx2080 target board.Even if I use the network port or USB for debugging, the simulator still shows that it cannot connect.And synchronized CodeWarrior Connection Server has encountered the following issues.

Have you ever encountered such a question? I have tried many of the methods provided in the official documents as well as those available on the internet, but none of them worked.

In the ccs, please run:

(bin) 7 % delete all

(bin) 8 % config cc cwtap:10.193.21.52//(it's your CWTAP ethernet IP)

(bin) 9 % show cc

(bin) 10 % ccs::config_chain {lx2160a dap}

(bin) 11 % display ::ccs::get_config_chain

(bin) 12 % ccs::reset_to_debug

@June_Lu Could you please send me the pin definitions (in the Jtag section) of the CodeWarrior Tap simulator? We are currently connecting the target board lx2080 through specific signals (TDI/TDO/TCK/TMS/RESET/VDD/GND). The CodeWarrior Tap simulator has been constantly indicating the above error.

When I click the connection button, the following problems will occur

And the CodeWarrior Tap emulator's light (RUN/PAUSE) remained orange all the time, which was not the red color as stated in the official documentation.

I'm looking forward to your reply,Thanks.

Could you ping the CWTAP?

What's your CWTAP version?

What's your CodeWarrior IDE version?

Thanks

@June_Lu Thank you very much for your reply.

1.I can ping the CWTAP,(Windows-cmd.exe use ping FSL082481 command,it's OK.)

2.We have two CWTAP emulator,one is <REV H 23201440>,the other one is <REV G 20461200>

3. My CodeWarrior IDE version is:

The latest upgrade package has also been imported.

Please update it to the CodeWarrior IDE version 11.5.12.

On the NXP website.

My NXP Account->Software->Software Licensing and Support->View accounts->Product List->CodeWarrior for QorIQ LS Series ARMv8 ISA->

Please download update package

com.freescale.armv8.11.5.12.GA.Win.updatesite.221209.zip

Please open CodeWarrior from C:\Freescale\CW4NET_v2020.06\CW_ARMv8\fsl_eclipse.bat, and install the update package from Help->Install New Software->Add->Archive.

And then try the ccs command.

You could reply in Chinese.

@June_Lu 感谢，软件已经升级到指定版本了

启动CCS后，按照您提供的输入指令，出现如下情况：

请问该如何定位问题呢？

用USB直接连接到PC上，用下面的命令，看是否工作正常

(bin) 8 % config cc cwtap

(bin) 9 % show cc

@June_Lu

用USB直接连接到PC上，用下面的命令，结果如下图所示：

Re: The CodeWarrior Tap simulator is unable to recognize

June_Lu — Thu, 24 Jul 2025 13:01:01 GMT

(bin) 7 % delete all
(bin) 8 % config cc cwtap
(bin) 9 % show cc

每次都要delete all
连上G version试一下，USB连接，H version，firmware变更了

@June_Lu

这是连上G version后的效果。

还有一些硬件问题麻烦您答疑一下，十分感谢。

1.连接仿真器时RCW_SRC[3：0]，还有TBSCAN_EN_B怎么配置?,也就是CFG_DRV置高开始配置的时候，配置完（复位完成后）这几个管脚应该怎么处理？

十分感谢

如果这个问题一直存在，建议你换一台PC机，重新安装CW试一下，并且确认使用CWTAP之前，设备管理器都可以识别CWTAP串口并能输入CWTAP的信息。

因为我手上的G和H version都无法复现这个问题。

LX2160ARDBGSG中，有对RCW_SRC[3：0]和TBSCAN_EN_B的配置描述。

CFG_DRV不知道您指什么。

我断开了CWTAP的网络连接，发现了与您类似的错误，请检查您CWTAP的连接。

(bin) 7 % delete all

(bin) 8 % config cc cwtap:10.193.20.174

(bin) 9 % show cc
