CCS/TMS320F28379D: program will not fit into available memory

Hi Hridya,

Did you use an existing example from C2000Ware or did you make any changes?

Can you try not using the  RAMM0 and RAMD0 for .text section?

Thanks, Katta

Existing example modified for my use, the main c file was modified. 

I am not sure how to disable the use of RAMM0 and RAMD0. Can you pls help? and what does that error exactly mean?

Hi Hridya,

Instead of 

.text : >> RAMD0 | RAMD1 | RAMLS0 | RAMLS1 | RAMLS2 | RAMLS3 | RAMLS4

try 

.text : >> RAMLS0 | RAMLS1 | RAMLS2 | RAMLS3 | RAMLS4

Thanks,

Katta

ok, what exactly does that men? could you please explain?

Hi,

The data section allocation happens from the left-hand side. So, I thought to try with removing the lower sized RAM sections.

Anyways by default, the data section gets created into a single section. The allocation to RAMs did not occur as a single section of ~0x1a19 is not available.

You can try combining the RAM sections or try using the option --gen_data_subsections and --gen_func_subsections as mentioned in the compiler user guide section 4.2 Linker Code Optimizations

Thanks, Katta

I tried modifying this as was suggested by you. still the error persists.

I am using sin and cos functions and math.h header file.

Not using lookup table for sine and cos. Is that the issue?

Hi Katta,

With this modification, it is building now. Thanks for the help.

I would like to know whether my DSP is operating in its limits of memory usage. Is there an option to check that?
