Compiler/TMS320C5517: C5517 HWAFFT did not work on SPI FLASH MODE

Tool/software: TI C/C++ Compiler

Hi. I'm jeongtae kim from south korea.

I used TMS320C5517( EVM5517 board) for FFT test.

In order to use hwafft function, i was coding, testing and i was verified on debug mode.

However, on SPI Flash mode, only FFT Function did not work. (Every function operated normally such as, UART, I2C, PLL, ADC,...)

I checked the boot mode switch and hwafft function code but, it worked normally in debug mode.

What is difference between debug mode and SPI Flash mode in hwafft function?

I attached my CMD file code. Please help me.
