Hello,

I am using _IQ30log() in my code. While building the code I got the below error.

Description Resource Path Location Type
unresolved symbol __IQ30log, first referenced in ********** C/C++ Problem

I searched for the error in forum and found multiple solutions. But none of them are working.

I even downloaded the library from below forum. "https://e2e.ti.com/support/microcontrollers/c2000/f/171/p/58620/208849#208849"

Hi Sanat,

Could you kindly provide the Device Revision (ex:Rev 0, Rev A, Rev B, etc), CCS version and the IQmath library version?

Besides, do other IQmath functions work correctly in your code and device?

Emma

Hi Emma,
I am using TMS320F2808 Experimenter Kit(TMDSDOCK2808), not sure about the revision. CMS version is 6.0.1.00040. I tried with both v150 and v160 iqmath library.

Yes other iqmath functions are working properly. I only get #16002-D build attribute vendor section TI missing warning for iqdiv and iqmathtable. I am ignoring them since they are working correctly.

Best Regards,
Sanat

Hello,

According to the IQMath quick start document, it looks like IQNlog supports N=1:29, so IQ30 isn't supported.
