Tool/software: Code Composer Studio

Hi,

I'm having a strange error when I try to connect a board with a 374S device.

Until now I've used the 377S and 379S without any problem.

Now I'm try to use the 374S device but when I start the debug procedure I receive the follow error:

I take a look into the F28374S.gel file and at row 82 I found the command:

The error cames when the debugger try to write 0x0FFF value to location 0x5F452, to initialize the GS0-GS11 memory blocks.

If I change the value to 0x00FF all works well.

If I set the value greater than 0xFF the error appears.

At this point I don't understand why the initialization of the GS8-GS11 blocks generate the debugger error.

Note that when I'm connect to the board and write manually the GS INIT register to 0x0FFF the initialization ends without error.

This is the DSP picture:

Can anybody give me an hint?

Thank you

Regards

Giuseppe,

Did you remember to update your target configuration file to reference the TMS320F28374S?

Hi,

yes, I've updated the target configuration.

Also I tried to erase the configuration file from the project directory and create a new configuration from scratch.

My actually workaround is to change the value in the gel file from 0x0FFF to 0x00FF, but I don't understand the reason of this change.

And I hate to do something without understand it.

Regards

Giuseppe,

Can you try this on another device (F28374S)? Let us know if you see the same issue.

Yes, I've tried two different boards and the behaviour is the same.
I have other 2 sample boards. If you want I can do the test on them.
The emulator probe is the XDS510USB, CCS8.2 (but was the same with 8.1), W10 64bit running on a VMware Player virtual machine.

Hi,

Once connected, can you try writing to that location via CCS memory watch window and see if there is any error.

Hi,

maybe I found the problem:

The 1.2Vdd was exactly 1.2V after the power supply, but after the LC filter near the DSP chip it was about 1.10/1.12Volt when the CPU starts to work.

I've increase the power supply output to 1.26Volt so at the DSP pins arrive about 1.19/1.20Volt when cpu starts.

By now the problem seem to be solved also using the origina .gel file.

I'll tell you if the fix doesn't solve the problem.

Thank you for the help.
