Other Parts Discussed in Thread: CCSTUDIO, OMAP-L137

hello,

I am using the board for the first time. i FOLLOWED SOME BOOKS ABOUT C6XXX PROCESSORS  and everytime i get errors about the memory . can somebody please tell me how to write the command file to run a simple souce code, its very important.

this the cmd file that i used:

/*MEMORY MAP1 */

MEMORY
{
 PMEM : origin = 0x00000000, length = 0x00010000
 EXT2 : origin = 0x00000000, length = 0x01000000
 EXT3 : origin = 0x00000000, length = 0x01000000
 DMEM : origin = 0x00000000, length = 0x00010000

}

SECTIONS
{

  .vectors > PMEM
  .text  > PMEM
  .bss  > DMEM
  .cinit  > DMEM
  .const  > DMEM
  .stack  > DMEM
  .cio  > DMEM
  .sysmem  > DMEM
  .far  > EXT2
  .mydata  > EXT3
}

 

the errors:

"C:\\CCStudio_v3.3\\tutorial\\dsk6711\\dm1\\First.cmd", line 6: error: EXT2
   memory range overlaps existing memory range PMEM
"C:\\CCStudio_v3.3\\tutorial\\dsk6711\\dm1\\First.cmd", line 7: error: EXT3

  • Which EVM are you using? If you are using OMAP-L137 you should use the example software that is provided with the EVM.

  • I checked the examples like the timer and the sine wave but i see running at the bottom left corner, thats it. from where should i see  some output.

    I want to see the analog signal which i give from the function generator to the line in and i want to see the out put in the osciloscope which i connect to line out, if you can help me with this simple program how to use the board to solve this I can do rest of the things like modulation and coding and all.

    how should i see the out put, there are no text books for this board , when i try to read some books for tms320c6000, it says that the target selected is wrong and the cmd file has all the wrong adresses.

    I need help in using this board as my seniour project is due next month.So, i would really like to know how to work  on the signal.
