I am new to C2000, I need 3 array of 4096 Uint 16 to do fft.I just changed RESULTS_BUFFER_SIZE to 4096 in the example "adc_soc_continuous_dma"

below are the 2838x_flash_Ink_cpu1.cmd:(by the way,if I choose to load by 2837x_RAM_lnk_cpu1.cmd,another error occurred BEGIN memory range overlaps existing memory range BEGIN.)

I guess this is not about lack of memory. I find that global variables are in .ebss

But in my case it's about section "ramgs0". I don't know what is section "ramgs0".

When I choose to load in RAM, this happens

Hi,

Look like in your project two linker command files are linked hence getting this issue. Please check the project property and remove addition linker cmd file.

Thanks for your reply

The issue that I cannot upload via ram has been solved, it is just like you said.

But when I changed the RESULTS_BUFFER_SIZE from 1024 to 4096

That error still occurred :

<Linking>
"E:/C2000/C2000Ware_2_00_00_02/device_support/f2837xd/common/cmd/2837xD_FLASH_lnk_cpu1.cmd", line 97: error #10099-D:

error #10010: errors encountered during linking;
   "adc_soc_continuous_dma_cpu01.out" not built

I have uploaded that example.

Thanks again.adc_soc_continuous_dma.zip

Finally, I resolved this issue.

In the source code, there are two prepared statement ： #pragma DATA_SECTION(adcData0, "ramgs0");
#pragma DATA_SECTION(adcData1, "ramgs0");

Which means the section ramgs0(length 4096*16bit) was used twice to store a 4096*bit array.

This issue is about ignoring the prepared statement in the source code

Thanks all who give advice!
