CCS/TMS320F28379D: I can program one controlCard properly, while another board reports loader error

Steve Elliott1

Tool/software: Code Composer Studio

I have two R1.3 controlCards, both with TMS320F28379DZWTT processors with rev C silicon. The later board (bare pc board TEX137-A) operates fine. The earlier board (TEX137) gives me this error from the console:

C28xx_CPU1: GEL Output:
Memory Map Initialization Complete
C28xx_CPU1: Loader: One or more sections of your program falls into a memory region that is not writable. These regions will not actually be written to the target. Check your linker configuration and/or memory map.
C28xx_CPU1: File Loader: Verification failed: Values at address 0x82064@Program do not match Please verify target memory and memory map.
C28xx_CPU1: GEL: File: C:\...[file path removed for privacy] ...\Tester 2.out: a data verification error occurred, file load failed.

0x82064 is the address of __cinit__

I can make the earlier board program and run if I do this:

Launch and load the program into the working board

Suspend the processor and unplug the JTAG and power USB cables. This causes a power error et cetera on the JTAG

Plug both USB cables into the bad board.

Connect to CPU1 in the debug window

Run-Load-Reload Program (ctrl-alt-R) and the board programs and runs just fine.

I am using a very old version of CCS (7.2.0) and not really eager to change it because we've seen some compatibility issues in the past when we upgraded.

Do you have any suggestions for what is happening?

Thanks

Hi Steve,

I suspect you're being affected by the following:

Specifically, I'm guessing that the F28379D devices on your two cCARDs are from different fab codes - which is what is leading to the strange behavior.

That's at least what I'd start with.

Thank you,
Brett

Thank you for the quick reply, Brett.

The TEX137 board has a $7/Aug19 fab part in it (does load properly) while the TEX137-A board has a YF/Sep17 part in it (does not load properly). I am using the offline CCS 7.4 download, but it won't install (it's trying to download ti_emupack_setup_7.0.100.0.win_32.exe but it can't get it).

I'll try the CCS 8.3.1 version next.

It does seem a bit odd to me that it's a fab problem that could be cured by a software upgrade: the newer fab part is on the older board, but it runs right; the older fab part is on the newer board and it doesn't. If 8.3.1 doesn't fix the issue, I'll probably end up just throwing away the YF board.

Regards

Steve

Hi Steve,

For what it's worth, I agree that something doesn't quite make sense here. Let's see if 8.3.1 does indeed fix things.

Thanks,
Brett

Hi, Brett-

Both boards are working right under CCS 8.3.1.

Thanks for your help! I was going crazy over what I was seeing.
