PROCESSOR-SDK-OMAPL138: DSP App stop when run IntDSPINTCInit() function.

Part Number: PROCESSOR-SDK-OMAPL138

Dear TI team,

I am trying to create a DSP application base uart_c674x project example in Starterware SDK.

In debug mode (JTAG XDS100 V3.0), this application can run normally.

But, when I write the app to Flash, It always stops in IntDSPINTCInit() function.

After research, I found that the app can not access to ISTP register.

I checked the Execution Modes of the device by reading the TSR register. The value is 0x13, so CXM value is 0 mean Supervisor mode.

But, I still can not access to ISTP register.

Could you help me to resolve this issue? I attached my source code.uart_C674x.zip

Regard,

Quy

Hello Quy,

Starterware is a legacy software package that is no longer being supported by TI. Please migrate to Processor SDK: www.ti.com/.../PROCESSOR-SDK-C6748

Processor SDK RTOS documentation is located here:
software-dl.ti.com/.../index.html

Documentation on the UART driver and examples is located here:
software-dl.ti.com/.../index_device_drv.html

The UART example projects can be built by following the instructions here:
software-dl.ti.com/.../index_device_drv.html

If you have any questions please let me know.

Regards,
Sahin

Dear Sahin,

I try to create a Project using UART with the new SDK.

Follow this link:

But it is not successful. Please help me to fix this issue.

Hello,

Did you run pdksetupenv.bat before pdkProjectCreate? Also, please make sure the SDK products are discovered and installed in CCS.

I was able to build the example project without issue on SDK v5.2:

Hi Sahin,

Of course, I run the pdksetupenv.bat

Here is my console log

I have some questions:

1. Where does the log "The system cannot find the path specified." come from?

2. Which "path" does the system looking for?

Regards,

Quy

Hi Quy,

It comes from the pdkProjectCreate.bat script. Specifically, lines 769 - 775.

Perhaps it's a permission issue. Can you try running as an administrator? And can you make sure the folders are not set as read-only?

Regards,
Sahin
