Unable to access the DAP on RM42 Hercules Development Kit (HDK)

Other Parts Discussed in Thread: RM42L432, HALCOGEN

I'm completely new to both Hercules platform and CCS5.

I'm working on TMDXRM42HDK and I have the following problem.

I've written an as useless as dumb program to start to work with the evaluation board, just to see if I'm able to create a project, compile, download a program.

All works fine until I add a variable to "Expression window" to watch its value.

In that moment, infact, the program is stopped and in the console window appear the following error (in a red terrifying font):
"CortexR4: Trouble Reading Memory Block at 0x8001510 on Page 0 of Length 0x2: (Error -1170 @ 0x0) Unable to access the DAP. 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 5.1.114.0) ".

If I resume the program I think it runs correctly, but if I try to change the variable value the same error appear in th console window and the program stops again. In these way is very difficult debug the application. What am I doing wrong?

I've tryed to restart the board, CCS5 and the PC but nothing change.

Which other information do you need to help me to solve my issue?

Thank in advance.
Paolo

I'm adding some useful information for anyone who wants to help me:

Code Composer Studio Version: 5.4.0.00091

Emulator XDS100v2 Integrated on demo board.

This is my main function; as I've say before is just a variable incrementing cycle, to test if I can "watch" variables.

Thank you.

Paolo

/* USER CODE BEGIN (2) */

uint16 DebugVar1;
uint16 DebugVar2;
uint16 DebugVar3;
/* USER CODE END */

void main(void)
{
/* USER CODE BEGIN (3) */
   while (1)
   {
       if (DebugVar1 == 1)
       {
           DebugVar1 = 0;
           DebugVar2 ++;
       }
       else if (DebugVar1 == 2)
       {
           DebugVar3 ++;
           DebugVar1 = 0;
       }
   }
/* USER CODE END */
}

Paolo,

In order to help you with your problem, could you zip your project (including Halcogen) and share it?
I will be then able to reproduce your error.

Thanks,

The project folder is zipped and attached, there is even the ".hcg" file.

I remind you that the problem happens when you add variables to watch window or edit their value.

Thank you for the support.

If you need something more, please, feel free to ask me.

Paolo.

Paolo,

I'm able to reproduce the problem you are facing. At that point, I don't know what is going on.
I will continue working on this problem and will be back to you as soon as possible.

Paolo,

The problem was reproduced and has been fixed by CCS software development team.
A new driver for XDS100/XDS510 and XDS560 that corrects the issue has been released.

These new drivers will be deployed in CCS5.5 to be released in the next few days.

Please check at the following link for downloading CCS5.5

Thank you, Jean-Marc.

When the new version of CCS will be deployed, I'll do some tests and, if it works, I will mark as "verified" your answer.

I hope It will be possible to upgrade my installation even via "help -> check for update" function in CCS5.4, and not only downloading the full package, and reinstalling it from the begining.

Paolo,

For your information CCS v5.5 is now available for download at

http://processors.wiki.ti.com/index.php/Download_CCS

I will download it to make a try.

Thank you Jean-Marc,

do you know if the update can be installed via CCS update feature (Menu "Help" -> "check for update").

I've tryed but it give me an error.

I'd prefer this way, instead of download the huge full installation package.
If this is impossible I will download the full installer from the link you gave me.

Before to go on, I'll wait your answer.

Thank you in advance.

I attach the update error print screen.

Paolo,

The Driver update is part of CCS V5.5 installation.

I did installed the full CCS V5.5 on a blank Win7 for checking and the problem is no more visible.

I do not know if the driver update on CCS V5.4 is possible. You may have to install the full new CCS V5.5

I had the same error in that a CCS 5.4 installation said an update for Hercules Emulation version 5.5.0.6 was available, but couldn't be installed due to a missing dependency.

Looks like the Hercules Emulation version 5.5.0.6 has been packaged with a dependency on the installer for CCS 5.5

Jean-Marc, thank you for the support.

The specific issue is solved in version 5.5, even though the"Expressions" window behaves a bit differently than I expected.
Can I explain my doubt on this thread or is better that I open an other thread?

I've try to click the green "yes" button at the bottom of your post, but nothing happens, and the button "verified answer" is not shown.
