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.(Please visit the site to view this file)

Regard,

Quy
