Error using IQmath functions in F2812

Hi everybody,

1) I am using IQ numbers for my calculation. But having the following error, can you please tell me how can i rectify that? I have included F2812.cmd and IQmath.cmd file. Is it because of that? Is it necessary to include IQmath.cmd file? should i change any setting in memory or sections part of both the linker files?

---------------------------- checknew.pjt - Debug ----------------------------

>> C:\tidcs\c28\IQmath\cIQmath\cmd\IQmath.cmd, line 24: warning:

2) Can i run my program having IQmath computations in RAM having F2812_EzDSP_RAM_lnk.cmd file?? If so, what modifications i should do it in linker file.

3) If i remove, IQmath.cmd file, it didn't show the above error and i am able to run my program. but if i look at watch window, all register values are zero. For a variable i have given
_iq19 x412, but it shows wrong value like 1983962114 , type iq19, radix decimal in watch window. I didn't get any output. But able to run the program in flash. what is the reason? I have assigned some routines to run in RAM which has IQmath statements. Is it because of that? If i use the following function, is it a valid one in IQmath?

Y=_IQ19div(_IQ19mpy(X,4),1245);

Thanks a lot in advance. Please answer me.

regards

Hi,

you have probably multiple definitions of section 'IQmathTables' and
'IQmath'. Safe way is to write your own .cmd file, don't use multiple
predefined files together.
