TMS320C6678: How to use the MSMCSRAM memory as L2SRAM got overflowed

Harshul Agarwal

Part Number: TMS320C6678

Hello,

I am working on TMS320C6678 with Processor SDK 5.2. I am taking samples through SPI peripheral and then computing FFT and CWT on the received data. While building the code, the error came which showed that program won't fit in available memory. The below screenshot shows the memory allocation on the board.

So, I want to use the MSMCSRAM to store all the data. What changes should I make to put the code the MSMCSRAM rather than L2SRAM?

Thanks and regards,

Hi,

You need to modify your linker.cmd file. You can check what each section in the linker.cmd file is here:
software-dl.ti.com/.../sdto_cgt_Linker-Command-File-Primer.html

For example if you want to move the .data to MSMC you should modify:
.data: load >> L2SRAM
to
.data: load >> MSMCSRAM

Also check your .cfg file for additional settings and change accordingly if needed.

Best Regards,
Yordan
