Concerto F28M36, Error connecting to the target: (Error -2131 @ 0x0) Unable to access device register

Hi Everyone,

I recently received a new Concerto Development tool (F28M36 P63C2 daughter card+Docking station) and I was very exited to test it. I installed the Code Composer Studio Version: 6.0.1.00040 and I imported ADC SOC C28X example file from F28M36X "code examples" folder.

First of all, why should it be so difficult to run an example file? it took me a couple of hours to get my head around the example code and how to get rid of 7 errors that it was giving me. turns out that I had two cmd files one in common folder and on in the example project.

Anyways, I can now build the imported project. I have green ticks for Step 1 and 2! for Step 3 after a few hiccups I could select the XDS100V2 which I believe the correct inbuilt debugging tool. so that is fine as well.

Step 4 Debug the imported project I am receiving this error:

Error connecting to the target:
(Error -2131 @ 0x0)
Unable to access device register. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK).
(Emulation package 5.1.507.0)

I have not done any changes to the board so everything is factory default.

Am I missing anything there?

I appreciate your comments

    Hi Everyone,

    Keep cool, I was missing power!!!

    There was no power supply in the box and only one USB cable so I assumed it is the only cable I need.

    Well now with two USB cables one to the docking station (power supply) and one to the control board (communications) it is working fine!

    Cheers,

    You should've gone through the workshop/training session first for quick understanding of the structure and methodology. You can find the same here:
