CCS/TMS320F28377S: Error in flashing loading

Hello,

It looks like the JTAG expert is out today. He should be back on Monday.

In the meantime can you go through these documents and verify that you are following all relevant recommendations?

There are some good links and FAQs in this wiki page. please reference them as well.

If you search your exact error message on e2e, you will find additional threads on the same topic. many with resolutions that may help you out as well.

Regards,

Thank you so much Mark!

I will try to check JTAG again as ur note

Dinh,
Can you disable the "auto-run" to main when program is loaded feature? This is under "Tools" -> "Debugger Options" inside of CCS in the debug view. I want to see if this error still occurs if we just load your program.

Another thought, if the example file is failing to load to flash, are any of the CSM passwords programmed to the device? If these have been changed from the erased state, and the device is not unlocked then CCS won't be able to load code to the flash.

Hi MatthewPate ,

I have the same error with Dinh, so i tried your recommends. But it seems these errors still occur if i just load my program.

Beside that, i have no idea about CSM passwords.

Part Number: TMS320F28377S

Tool/software: Code Composer Studio

Hi all,

I designed a custom board based on TMS320F28377S chip. My problem is that I can load firmware (Example project from C2000Ware) into SRAM but cannot run. Errors are showed by CCS as bellow:

"Break at address "0x3fe493" with no debug information available, or outside of program code."

I defined "_LAUNCHXL_F28377S" in Predefined Symbos and then i found out that problems come from InitSysCtrl function -> InitSysPll function -> Block of code bellow:

    SCSR = WdRegs.SCSR.all;
    WDCR = WdRegs.WDCR.all;
    WDWCR = WdRegs.WDWCR.all;

    //
    // Disable windowed functionality, reset counter
    //
    EALLOW;
    WdRegs.WDWCR.all = 0x0;
    WdRegs.WDKEY.bit.WDKEY = 0x55;
    WdRegs.WDKEY.bit.WDKEY = 0xAA;

    //
    // Disable global interrupts
    //
    intStatus = __disable_interrupts();

    //
    // Configure for watchdog reset and to run at max frequency
    //
    WdRegs.SCSR.all = 0x0;
    WdRegs.WDCR.all = 0x28;

It means that errors dont occur if i comment them, but the program stills cannot run.

I have no idea to fix this problem so hope to hear any idea.

Tks all!

Hi MatthewPate,

Sr, i can't find edit option in comment. This picture show errors when turn off auto-run.

Can you look at the pin "ERRORSTS" and see if it is high or low? This pin will indicate if there has been a NMI type event if it is "high" after you see the issue with CCS.

Based on the settings and the issue is with programming the flash I am thinking there may be an ECC error; caused by not programming the ECC values for the memory that is being loaded. This should be enabled from CCS by default(auto-ECC gen) under flash tools.

Hi Matt,

I'm using 100-Pin PZP package of F28377S, so it seems that it don't have ERRORSTS pin. Further, i checked auto-ECC generation and it is enabled as the picture follow.
