28346:Is there a limit firmware size to use Stand-alone?

For operating Stand-alone, I use a external Flash (512Kb).

 

But there is a problem. When HEX file is written the external Flash by over 144kb,

 

It does not work by Stand-alone.

 

However, When HEX file is written the RAM by the J-tag, There is no problem.

 

 

As you can see the Map file below, RAM is enough.

 

        name            origin    length      used     unused   attr    fill
----------------------  --------  ---------  --------  --------  ----  --------
PAGE 0:
  BEGIN                 00300000   00000002  00000002  00000000  RWIX

  BOOTROM               003ff27c   00000d44  00000000  00000d44  RWIX
  RESET                 003fffc0   00000002  00000000  00000002  RWIX

The options are as follows: to create a HEX file

hex2000 a.out-i-o a.hex-boot-spi8-e 0x300000-lospcp 0-spibrr 4

 

Is there a limit size to use Stand-alone?

Thank you.

    There is no limit as such. Are you sure that your external flash has not been corrupted? Did you try replacing the flash?

    I found the cause of this problem. 

    http://e2e.ti.com/support/microcontrollers/c2000/f/171/p/190313/698147.aspx

    It problem occur when .text block size is over 0xFFFF.

    but I don't know how to fix it problem.

    Thank you.

    June,

    yes this is a known issue, I need to check if the tools are being updated for the fix.

    Meanwhile would you be able to edit the blocks in the hex file manually or with a script, to be less than 0xFFFF in size. Like divide up the third block which is >= 0xFFFF in size into two:  where you put some first 0x02 (min) words from the big block into first divided block and the rest into another one. The data remains unchanged all you would do is wherever you find 0xFFFF for length you put 0x02 and then leave two data words and the add at length field of 0xFFFF-2 and leave the rest as it is. Then proceed to the next block.

    Hope this helps..

     

    Best Regards

    Santosh
