TMSR2812 Global Variables doestn work

Other Parts Discussed in Thread: TMS320F2812

Helow, I have a program  that I did for F2812 in code composer 3.1 and this program work very well. Now I imported the program using CC 5.4 for a R2812 and the global variables doesnt work, only local variables. I need some help.

Thank you

    Hi,

    Can you just give us a snapshot of how you're declaring your global variables and how're they not working for you (any errors or warnings?)

    Regards,

    Gautam

    Hi, follow the file main.c. Actually there is no error in the variable, only it does not store any after doing some regard for example, it updates only if it is a local variable value.

    In the program bellow see only the variable call "nl and n" declared in line 125 and 126. "nl" is declared again in line 199 as a local varable and the simple code in line 306 and 307. "nl" increment but "n' stay with "0".

    Thank you

    Hi,

    I'd a look at your code, there doesn't seems to be any issue. I would like you to check with the "Step into" functionality (ie step by step towards the line "n=nl") during debugging. Check whether you reach that particular line or not. If not then what is it that stopping you. Let me know what you observe.

    Regards,

    Gautam

    Janderson,

    When you updated to CCS 5.4, did you start using a new compiler version? If so, did you update your linker command file? The .bss section needs to be in RAM for global variables to work.

    You can check the .map file in the output directory to see where your global variables are in memory. Make sure that the address is in RAM.

    Hi, follow the 2 pictures during debugging with line n=nl. Very Thank you

    Hi, I imported using CC. 5.4. I did Project->Import Existing CCS Eclipse Project, just it. And I didint change the linker file, I am using the same that was imported and work for F2812, but dont work for R2812. I think the problem is samething like you said, but I dont know how to fix, I already tried to change linker file by the file of R2812 from CCS, but I didint get. Follow my file .MAP, I dont understand  very well this file, If you could look for me. The . BSS Section start in 00008000 and the dissasembly picture it send to the position 0x200, I dont know if this is important. Thank you.

    I don't see anything obviously wrong with the assembly or the .map file. The global variable is in the L0 SRAM, which is fine. Can you provide a screenshot that shows the CPU register values right before the MOV @0xd, AL instruction is executed?

    Also, can you try initializing the variable to a different value? Instead of:

    int j=0,
        l=0,
        nl=0,
        n=0;

    You could do:

    int j=0,
        l=0,
        nl=100,
        n=0;

    Thanks,

    I change the initialization thr variable but still the same thing. Once a support of TI Run the same project in a KIT F2812 and it worked, but in my KIT R2812 dont work. Follow the picture. Thank you.

    Now I tried to initialize the variable "n" to 1, but it remains with 0.

    I Changed the configuration target to TMS320F2812 and it worked very well. But Code Composer gave the message: 

    28xx: Flash Programmer: Warning: The configured device (TMS320F2812), does not match the detected device (). Flash Programming operations could be affected. Please consider modifying your target configuration file.

    Do you think it is a problem? The fact is is I configure with TMS320R2812 dont work and with TMS320F2812 work. I can continue using this way?

    Very thank
