Connection error between CCS v5 and TMS320F28335

Other Parts Discussed in Thread: TMS320F28335

Hello,

I can’t connected my DSC with CCS v.5

I’ve worked with CCS v3.3 and the 28335 device (in the Spectrum Digital Starter Kit, the eZdsp F28335 board, and programming through USB) for a long time. Last week I upgraded to CCS v5.

I’ve read and followed the steps on the C2000 Getting Started wiki but when I arrive to the “Connect to the Target” step I’m unable to create the connection between CCS and the 28335 and it turns up the error message: “No source available for 0x3ff9ce”.

I’m using and Ti example for 28335 (Example_2833xGpioSetup) and I imported it like the Wiki suggested. In the Target Configuration I’m using a “Spectrum Digital DSK-EVM-eZdsp onboard USB Emulator” and the “TMS320F28335”.

Somebody can say me where I’m wrong?

Thank you very much,

Albert

    The message “No source available for 0x3ff9ce” in itself is not a problem. It sounds like the connection was successful.  That message appears because there is no source available at that time since no program has been loaded to the target yet. You can open the disassembly view by going to menu View->Disassembly and see where the Program Counter is halted. Please continue to follow the steps in the wiki page to build and load the program and let us know if you have problems loading and running the code.

    Yes, this is as you say. I’m a bit lost in the new interface. Thank you very much for your response.

    Hi,

    Today I was working with F28335 and all of a sudden the board stopped working. When I tried to reset the CPU the message "No source available for "0x3ff9ce" appeared. I opened the disassembly view as suggested and the program counter is halting at "3ff9d8: 767FF674 LCR 0x3ff674".

    Can somebody tell me what happened?

    Thanks a lot

    Hi,

    I tried to hit the run button but it still doesn't work and the watchdog timer is also disabled.

    I tried to debug an old program by turning one GPIO pin active high and the DS201 led of eZdspF28335 board is flashing every time I click the step over button. However the GPIO pin of F28335DSP is not turning high.

    Is it possible that I have damaged the DSP or eZdspF28335 board?

    Thanks in advance
