CCS/TMS320C5535: Computation of 4096 FFT, error - "twiddle_buf" undefined

Part Number: TMS320C5535

Tool/software: Code Composer Studio

Hello,

In response to the thread - https://e2e.ti.com/support/dsp/c5000/f/109/t/269367 , I am getting compilation errors in sample code (3 files - 5808.test.c; 5187.test.cmd; 1460.twid4096.asm) provided by Mark. As I am new to DSP, could someone please help me resolve this?

I want to compute FFT of 4096 points

Error - "twiddle_buf" is undefined.  I have linked the "1460.twid4096.asm" file and added the "5187.test.cmd" to the project. Attached below is the screenshot.
