OMAP-L137: OMAP-L137 EVM

Thanks for your reply but my issue is still unresolved. My current dip switch settings of SW2 on Spectrum Digital Board OMAP-L137 are as under:

Switch position                                  Current setting

1                                                        ON

2                                                        ON

3                                                       ON

4                                                       ON

5                                                       OFF

As per manual these settings correspond to "Emulaton Debug" mode.

I may try other settings if you think these settings are not correct.

Hello,

The boot mode setting looks correct. What emulator are you using?

The board has an embedded jtag emulator equivalent to spectrum digital xds 510 usb. I am using the 8.3 version of CCS and it supports this emulator.

Please check the CCS documentation here regarding PRSC connection errors. If you are still unable to resolve the issue, I'll loop in CCS experts to help.

Please go ahead and loop in CCS experts to resolve this issue.

Software:  Code composer version 8.3 running on Windows 11

Please note that CCS 8.3 does not support Windows 11. The last Windows version supported is Windows 10.

Please see the below link for more details on this error:

It is typically a hardware configuration error. Also, as noted above, your environment is not an officially supported one. There are no guarantees that CCS 8.3 will run well on Windows 11. The upcoming CCS 11.1 release will be the first version of CCS to officially support Windows 11. 

Thanks

Thanks for the reply. In fact I have also tried to debug the simple "hello world" program on the same hardware under the following environment:

Windows operating system ver 7 32 bit

Code composer studio ver 7.0

Even under this environment, I am getting the above cited error message. Target configuration in CCS does not show any connectivity issue and so does the Spectrum Digital emulator configuration utility.

Did you look at the details in the troubleshooting section and try the suggestions? As mentioned, this is usually some hardware configuration issue - especially if the "Test Connection" feature is passing.
