CCS/TMS320C5505: 4096 point HWAFFT calculation error

Part Number: TMS320C5505

Tool/software: Code Composer Studio

Hello,

I am getting compilation errors and warnings in sample code (3 files - 5808.test.c; 5187.test.cmd; 1460.twid4096.asm) attached below. 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.
