Emulator will not stay connected

Hello,

Are you using a USB hub with your laptop or are you plugging the cable directly to a USB port physically on your laptop?

Thanks

I am plugging directly into the laptop.

Hi

Check this: http://e2e.ti.com/support/development_tools/code_composer_studio/f/81/t/220692.aspx

I know it's a different OS and emulator, by trying updating the driver too.

Regards

I believe my driver is up-to-date, but I'm not sure how to check that.

You can try updating it via the eclipse update manager. It will check for updates;

My driver is up-to-date.  The problem persists.  Are there any other diagnostics that I can run?

Update:  I disabled USB 3.0 in the BIOS and the operation appears to have changed slightly.  After connecting the USB cable, I can run 3-4 successful Test Connections in a row before it fails.  Previously only the first one worked until I switched USB ports.

I used CCSv5.5 with an XDS220 and a C55x board (C5509A). I am able to use the Test Connection feature many times in a row without issue. I tried it with a USB2.0 port and a USB3.0 port and both work fine.

I have seen the error you describe before however. I got it when I prematurely shutdown CCS (or maybe CCS hung and I CTRL+ALT+DEL). Anyway the debugger was not shut down cleanly and the emuation connection was never properly disposed of, hence the error. The emulator had to be re-enumerated like you mentioned. But that is the only time I saw it.

You describe the error in the context of the Test Connection feature. But why are you trying to run the test many times in a row? Not that it shouldn't work... it should. But just curious.

Another suggestion, try updating the emulation drivers via CCS update manager.

Thanks

Emulation drivers are updated.  I'm running the test because when I try to debug I get:

Error initializing emulator:
(Error -2083 @ 0x0)
Unable to communicate with the emulator. Confirm emulator configuration and connections, reset the emulator, and retry the operation.
(Emulation package 5.1.507.0)

The emulator appears in my device manager as:

XDS2xx Emulator CDC Serial Port (COM3)

XDS2xx User CDC Serial Port (COM4)

Is that correct?

Can I see your test results when it passes?

Sure:

This utility has selected a 560/2xx-class product.
This utility will load the program 'xds2xxu.out'.
The library build date was 'May 21 2014'.
The library build time was '18:02:25'.
The library package version is '5.1.507.0'.
The library component version is '35.34.40.0'.
The controller does not use a programmable FPGA.
The controller has a version number of '13' (0x0000000d).
The controller has an insertion length of '0' (0x00000000).
This utility will attempt to reset the controller.
This utility has successfully reset the controller.

This test will use blocks of 512 32-bit words.
This test will be applied just once.

All of the values were scanned correctly.

Is the below summary correct:

Using CCSv5.5 w/XDS200 on a Windows XP PC - no problems. Everything works fine

Using CCSv5.5 w/XDS200 (same one as above) on a Windows 7 PC:

-Error Initializing Emulator issue when starting a debug session
-Can not run multiple Test Connection tests successfully (USB2.0 behaves better than 3.0)

Have you ever been able to start a debug session and connect to the board via CCS on your Windows 7 PC?

All of that is correct.  I have not been able to start a debug session on the Windows 7 PC.
