DSP and FreeRTOS

Posted by Mariano on November 21, 2012
Hi.

I´m developing with LPC1769 using LPCXpresso and I have a problem.
I have downloaded the DSP library from nxp and tested the testbenches that come in it, and they work great. But when I try to add that code into a FreeRTOS project I get the following:
undefined reference to `vF_dspl_fftR4b16N256'.
Do you know how may I fix that?

Thanks in advance

Find where vF_dspl_fftR4b16N256 is defined in the non FreeRTOS project that compiles. It will either be in a pre-compiled library or in a source file. Add the library or source file to your FreeRTOS project.

LPCXpresso projects often need the CMSIS and DSP projects in the same workspace. Both are available in the NXP LPCXpresso installation directory.
