CCS : Connection problem after upgrading CCS 4.2.3 to CCS 4.2.4

Hi,

I am working on our own board using LM3S9B96 with a XDSUSB 510 JTAG and Code Composer Studio.

Until yesterday we were using CCS 4.2.3 and everything working fine except a bug of CCS concerning a wrong display double floating point for Stellaris micro-controller.

Today morning we updated our CCS at the version 4.2.4.

And now it is impossible anymore to connect the target.

The XDS works correctly because when i running SDConfig , i got this message

Spectrum Digital Configuration and Diagnostic Utility
Supports:
Printer Port: XDS510PP, XDS510PP+, SPI515, eZdsp
ISA Bus:      SPI510, XDS510
PCI Bus:      SPI525
USB Bus:      XDS510-USB
** Using emulation application from directory c:\program files\texas instruments\ccsv4\emulation\drivers
** Checking for a valid emulator/eZdsp
  $$ You are connected to:
  $$ EmuProductName=XDS510USB
  $$ EmuPortAddr=0x510
  $$ EmuPortMode=USB
  $$ ProductId=510
  $$ ProductVersion=86

** Emulator Scan Test

   -- Found JTAG IR length of 4

   -- Found 1 JTAG device(s) in the scan chain

 

But when i want to debug my project, i got this error

Error connecting to the target:
Error 0x80000240/-140
Fatal Error during: Initialization, OCS,
Error generated by SD scan controller module

I tried to desinstall and reinstall the XDS driver but it is not the problem. I am checking the gel file and it is correct,....

Do you have any idea to solve this problem ?

Thanks you so much

Alex

    Hi Alex,

    how did you do the update?  Did you try taking the step to 4.2.5 (absolute latest)?

    What did you do with your project/workspace?

    Have you tried importing the project into a fresh workspace?

    Aside from the connecting to the target, do you get any other errors at all since the update?

    Best Regards,
    Lisa

    Hi Lisa,

    I found the solution. In my target configuration of my project, I selected Spectrum Digital XDS510USB Emulator_0 as connection. But with the version 4.2.4 of CCS, when you check the connection properties, you have now access to the same configuration menu that you have with SDConfigEx v4. It was not the case with older versions of CCS.

    This configuration bypass the configuration that you can do with SDConfigEx v4. And as the configuration by default is not correct in CCS for the Stellaris component (TCK Mode is by default in Counter Mode), it was not working.

    Now it is working well.

    Thanks

    Best regards

    Alex
