I've never been able to make LDFLAGS add a library to a user firmware build. I had to manually hack the Makefile in the system firmware source to do it. There's likely a better way, but it wasn't immediately obvious.

Integrate CMSIS library into Firmware

I am still facing a problem while using the actual fft routine. arm_rfft_q31( &rfftStruct, buffer, buffer); Calling the actual fft function leads to the following undefined reference: /u/susom/cmsis-integ/CMSIS/Lib/libarm_cortexM3l_math.a(arm_cfft_q31.o): In function `arm_cfft_q31': /u/susom/cmsis-integ/CMSIS/DSP_Lib/TransformFunctions/arm_cfft_q31.c:139: undefined reference to `arm_bitreversal_32' arm_bitreversal_32 happens to be defined in assembly code in the CMSIS library - arm_bitrever…
