Error after I debug the program on TMS570LS3137 USB stick.

Shivaram,

This isn't an error really because when you press the nPORRST button it resets the TAP (JTAG) on the MCU which makes CCS a little crazy because now it doesn't know what state the target is in... that's why you get the error.

If you want to avoid the error:

- Ctrl-Alt-C to disconnect the target.
- Press nPORRST
- Ctrl-Alt-C again to reconnect to the target

As long as you are disconnected from the target you can press nPORRST.

Otherwise limit yourself to nRST -or- Debug->Reset->System Reset and you won't lose the JTAG connection.

Hi Anthony ,

Sorry for the delayed response.

I tried the steps you mentioned but the problem is I am not able to flash the program.

Once I build the project and debug , it stops at :

CortexR4: GEL Output: Memory Map Setup for Flash @ Address 0x0 [message from console window]

I get the same error with the other demos too .

Can you suggest a possible solution of this .

Hi Shivaram,

That is a normal message the appears in the console. It just means the flash is mapped to it's normal address range.

Are you actually seeing an error? Are you sure you are not just halted in main()?
Maybe post some screenshots to give us a better idea of what this looks like?
Thanks and Best Regards,

Anthony

Dear Anthony,

I now understand the message on the console window(i.e CortexR4: GEL Output: Memory Map Setup for Flash @ Address 0x0) is a normal message . But I still don't understand why the program's ".out" file doesn't load on the controller unless I press nPORRST.

I was not able to see this until I tried to turn on all the NHET LEDS on TMS570LS3137 USB following the Hercules tutorial(www.youtube.com/watch?v=tsVmpH6Pm2U) , the LEDS turned on only after I pressed nPORRST and then it displays an error message in the console window(i.e. Dap: Error: (Error -242 @ 0xFFFFFF0E) A router subpath could not be accessed. The board configuration file is probably incorrect. (Emulation package 0.0.0.0) ).

A short video clip that shows what happened after I pressed the nPORRST (www.youtube.com/watch?v=hw_VWGQxVz8).

In other applications where I want to read the data from serial port for example: if I need to read the light sensor values,I am not able to do that because the ".out"file loads only after I press nPORRST button and I get the above error message.
