CCS/TMS320C6657: EVM Load Fail

Joseph Kadifa

Part Number: TMS320C6657

Tool/software: Code Composer Studio

Hello,

I am attempting to use a Dell Precision T7400 to connect to a TMDSEVM6657LS EVM board. I am using CCSv5 and the operating system on the computer is Windows 7. I am attempting to run a "Hello World" program on this board through the XDS200 connection. I have successfully ran the "Test Connection" on the configuration file, but when I try to upload the "Hello World" .out program to one of the cores, CCS throws out the following error message:

C66xx_0: Trouble Writing Memory Block at 0xecd8 on Page 0 of Length 0x94: (Error -1190 @ 0x8000) Unable to access device memory. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.0.838.0)

C66xx_0: GEL: File: C:\Users\Liu\workspace_v5_2\Hello_World\Debug\Hello_World.out: Load failed.

C66xx_0: Error: (Error -1190 @ 0x0) Unable to access device memory. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.0.838.0)

How would I go about debugging this "Load Program Fail" error?

Thank you,

Joseph

Hi Joseph,
Can you provide the *.out file you are tying to load?

Thanks

Here is the *.out file I am trying to load in a zipped format.

Hello_World8.zip

Thanks. The application is built with some sections to be loaded at address 0x8000. That doe snot appear to be valid memory for my TMDSEVM6657LS EVM board. Did you build your application with a valid linker command file for your board? If not, I believe sample linker command files for the C6657 is available with the PDK.

Thanks

I did not create an additional linker command file. I am following a demo program and when I built it, CCS gave me two warnings as seen below:
#10210-D creating ".stack" section with default size of 0x400;
#10210-D creating ".sysmem" section with default size of 0x400;

Do these warnings provide any insight? Do I have to create my own linker command file?

Thank you,
Joseph

Does your demo program already use some linker command file? If not, then you will need to add one to your project as the default allocation (which happens when no linker command file is specified) is not valid

The two warnings are fairly harmless and not the root cause of your main issue.

I attached a simple cmd file that worked for me. Add it to your project and rebuild

Thank you! This file worked! After the program printed "Hello World", it yielded this message:
No source available for "C$$EXIT() at C:\Users\Liu\workspace_v5_2\Hello_World8\Debug\Hello_World8.out:{3} 0xc005cc0{4}"
Is that normal?

Thank you,
Joseph

Yes that is expected since you are at the exit point of the application. The exit routine is from the runtime support library

Note that the cmd file I provided is a really basic one that sticks everything into shared RAM. You'll likely want to use something a little more complete. I believe some cmd files come in the PDK for your device. You can ask in the keystone forums for more details.

Also I recommend reading the linker command file primer for more details on how cmd files work:

I will look into making my own. Thank you for your help!
