MSP430FR2433: Float calculation move from FLASH Memory to RAM

SUMIT CHAULYA

Part Number: MSP430FR2433

Hi,

I want to move my floating calculation from flash memory to ram memory. I am flowing this thread but i am getting some warning.

Thread link: MSP430FR5994: (ULP 5.2) Detected floating point operation(s). Recommend moving them to RAM during run time or not using as these are processing/power intensive - MSP low-power microcontroller forum - MSP low-power microcontrollers - TI E2E support forums

I have done like this.

#define adc (float)MAX_ADC_Ch_Volt/MAX_ADC_BIT

I am getting like this. unrecognized #pragma

What is issue? If this method is not correct, then that is the correct method to move float calculation flash memory to ram memory.

Regards,

Sumit Chaulya

You can define it like this

#pragma CODE_SECTION(yourfunction name,".ramfunc")

Hi, Gary.

Thanks, Warning solve. But i am getting same message for float operation. "Detected floating point operation(s). Recommend moving them to RAM during run time or not using as these are processing/power intensive". Can you please help me on this issue.

This message is "Advice" not a "Warning". For program correctness, you can ignore it without guilt. (This message can be disabled in "Build Settings->Build->Compiler->ULP Advisor".)

My guess is that the ULP Advisor can't really tell whether the floating point operations execute from RAM or not, only that floating-point arithmetic is being used. (Even for a human it's not easy to tell.)

That would put "yourfunction name" in RAM but what about the floating point library calls where all the work is done?
