TMS320C6657: DDR3 memory allocation when board_init included in project

BradS

Part Number: TMS320C6657

I am trying to develop a small application to test the external DDR3 memory of the C6657 processor. I am wanting to load to / run from the NOR (SPI) memory on the TMDSEVM6657LS evaluation module. The application is to use DSP/BIOS and simply initialize the hardware, test the DDR3 memory (i.e. read/write from the DDR3 memory) and transmit the results to the serial port. Since there is an example project written by TI that utilizes the serial port, I was using it as a base to develop my application from, i.e. UART_BasicExample_C6657c66xExampleProject.

However, when I compile this example project, the map file shows that the compiler allocates 4000000 bytes in DDR3 memory space for something related to profiling (i.e. ti.utils.profiling.ae66 : profilingHooksC66.oe66 (.fardata:benchmarking)). I have determined that this declaration only occurs when the board_init() function is included in the project.

I have tried to disable all settings related to the profiling but nothing I have tried has stopped this declaration from occurring. Can you point me to the configuration that will disable this declaration?

Any help is greatly appreciated.

Brad,

>>>>>>>I am trying to develop a small application to test the external DDR3 memory of the C6657 processor.

The application is to use DSP/BIOS and simply initialize the hardware, test the DDR3 memory (i.e. read/write from the DDR3 memory) and transmit the results to the serial port.

Already, a sample project by name "platform test" exist to do internal-and-external memory test. This project is part of "processor_sdk_rtos_c665x_6_03_00_106" under "pdk_c665x_2_0_16"

You can make use of the same program to test the DDR3.

Attached the video on how to build and run the platform test on C6657 EVM.

>>>I am wanting to load to / run from the NOR (SPI) memory on the TMDSEVM6657LS evaluation module.

Yes, you can flash this "platform-test" program into NOR(SPI) memory by following the flashing instructions given in the link below.

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1057566/faq-tms320c6657-how-to-flash-the-ibl-intermediate-boot-loader-into-eeprom-and-how-to-flash-the-application-binary-into-nor-how-to-boot-the-ibl-application-binary

Revert, if have any questions....

I attempted to follow the instructions in the video. However, the imported project did not compile. (see attached log) Any suggestions?7875.compile.log

Brad,

1. Make sure you use the CCS version - 9.3

2. In your log, it shows undefined errors about CSL . Please check and include the path of CSL package in the project properties.

Thanks for getting back with me.

I am using CCS 9.3 and the CSL package was already included.
1. I added an explicit reference to the CSL directory, but it still does not compile.
Would you be able to provide a build log from your project, so I can compare the compiler invocation statements to what my installation is doing? Or better yet a zip copy of the project you are working with?

Brad,

One important thing, before building the "platform test", you have to build the "platform lib", as I have shown in the video.

Have you built the platform-lib ? that is required for platform test...

1. Attached the build log here,

1. Build log of platform lib -
