Saving Memory greater than 32k words to a file?

MikeH

CCSv5.3

C5515

I am trying to save a block of 57k words of memory while in a debug session. However, when I use Save Memory, and use a start address of 0x8002 and a length of 57000, type size=16 bits., I get a file with zeros starting at 32768 and going to 65535. From 65535 to the end of the file appears to be correct. When viewing the actual memory in CCS, I can see the correct data where the zeros appear in the file.

What could be causing this 32k word hole in the file? FYI, I am compiling with a huge memory model.

    Mike,

    By looking at your other posts I imagine you are talking about a C5515, right? If so, I was able to dump both data and program memory without a gap on my C5515 USBSTK. However I am using TI Emulators package release 5.1.73.0 (check menu Help --> About Code Composer Studio, tab Installation Details), which may make a difference (a bug fixed, perhaps).

    If the target is different, would you mind sending it so I can try to reproduce this?

    Regards,

    Rafael

    Rafael,

    Yes (notice at the top of my post) I am using the C5515 and CCSv5.3. So hopefully there are no new bugs in my version of CCS.

    My target is a custom board. I am using a XDS560V2 STM emulator probe which communicates directly to the C5515 via JTAG pins. The gap appears in both the internal RAM memory dump, as well as a dump from my external flash memory (parallel using EMIF).

    When you say you are using TI EMulators package, does this mean you do not have a hardware emulator?

    Duh. Sorry, I haven't got much sleep lately...

    The memory dump function is very basic, thus the emulator shouldn't matter - however, I have some news: I thought I was running CCSv5.3 but I was in fact running 5.4. Doing the same operation in CCSv5.3 I can see the issue happening (zeros starting at address 0x8000 through 0x10000).

    Therefore it is fixed in the new release - would you mind giving this new version a try? I would strongly recommend installing it in a different directory and opening a new workspace (this avoids any disruption in your current development environment).

    The TI emulators package is the software component of CCS that contains all the emulation device drivers, which can influence in the interaction with the hardware.

    Rafael,

    Thanks for tracking this down. I will give it a try later. Upgrading in the midst of a product release is a bit of a bad idea....:)

    Mike,

    I hear you; I tried to dump memory using other methods such as GEL functions and scripts, but the issue persists.

    I apologize for the inconvenience,

    Rafael

    I'm just glad you found it.

    THanks!
