Memory Error

Hi,

I have error while building sv04 using makefile

"ggvf0.cmd", line 480: warning: no matching section
"ggvf0.cmd", line 616: error: run placement fails for object ".nonsharedfar",
   size 0x645e5a (page 0).  Available ranges:
   DATA_FAR_NONSHARED   size: 0x1b000      unused: 0x1aff0      max hole:   0x1aff0

can anyone please explain why this error comes...?

I have added TSU (resizer) part also in the sv04....

Thanks and Regards

Tushar

    Hi Tushar, did you modify ggvfo.cmd when you added TSU? if so could you please share with us the changes made?

    Thank you,

    Paula

    Hi Tushar,

    It looks like you added a big global array when you added TSU in sv04. By default the global arrays are taken as part of ".nonsharedfar" which will be allocated from DATA_FAR_NONSHARED in local L2. That's why you are seeing the above placement failure.

    If your newly added globals can be placed in DDR, please use "pragma DATA_SECTION" to manually place them in DDR. Example from one of your earlier posts:

    In C code:

    #define BUFFER_SIZE 10240 //PC-- change it for your buffer size

    unsigned int srcBuff1[BUFFER_SIZE];

    #pragma DATA_ALIGN(srcBuff1, 128);

    #pragma DATA_SECTION(srcBuff1, ".edma_ddr");

    In sv04 ggvf0.becmd:

    BUFFER_DDR            : origin = 0x90000000, length = 0x2800 

    (Note: need to change length for your buffer size; also need to adjust origin to make sure there is no overlapping with existing sections. Some memory shuffling can be needed.)

     ...

    .edma_ddr > BUFFER_DDR

    Thanks,

    Hi Hongmei,

          I am getting the below linking error while I am attempting to modify ggvf0.becmd file. I am surprised to see this error because the Requested memory is lesser than what is been allocated. Could you clarify my understanding?

    "ggvf0.cmd", line 547: error: run placement fails for object ".nonsharedfar",size 0x25530 (page 0).

    Available ranges:
    DATA_FAR_NONSHARED size: 0x256b0 unused: 0x256b0 max hole:0x256b0
    error: errors encountered during linking; "sv04.out" not built

    If it is possible, please do memory adjustment to increase size of DATA_FAR_NONSHARED until the linking error goes away. Then we can find the actual usage of ".nonsharedfar" section and other sections placed in DATA_FAR_NONSHARED. Some extra memory can be needed due to alignment.

    Thanks,

    Hongmei

    Thanks Hongmei, this approach helped me to resolve the Issue.
