Kinetis design studio arm_math libary problem

s-dwalln — Tue, 30 Apr 2019 16:59:26 GMT

Hey there,

I have to use the Kinetis Design studio for programming, because I use the MK10 MCU.

Before I used MCUxpresso and i didn't have the problem there. Also in other IDE's I never had this problem.

I have to use the arm_math libary to use the DSP FFT.

But I can't get the libary working. Everytime the IDE says, it can't find the the libary.

Is the libary not supported? I tried it in windows, macos and linux.

I do something wrong.. but I don't find the solution...

I attached some pictures of the configuration. The libary and and include files are located in the project folder. I defined the libary and set the link to the libarys. But the compiler doesn't find it.

Does anybody have a clue?

Thanks in advance

Hi David,

The library name is without the 'lib' prefix and without the '.a' suffix. In this case you should add the library as:

arm_cortexM4l_math

Hope it helps!

Regards,

Felipe

Thanks for the answer!

Sadly it doesn't change anything. I also tried that before.

But i just realized. that i get another failure code this time:

/CMSIS/DSP/Lib/GCC/libarm_cortexM4lf_math.a: file format not recognized; treating as linker script

/CMSIS/DSP/Lib/GCC/libarm_cortexM4lf_math.a:1: syntax error

I used the newest CMSIS (CMSIS_5-5.5.1) driver from ARM. Is it possible, that KDS doesn't work with this version? Or maybe there is a bug in the libary.

Hi Felipe

I already know this tutorial. I already used this libary several times.

But I finally got it working. Like I thought there is a problem with the newest CMSIS driver and KDS.

I downloaded the Legacy CMSIS version 4.5.... and Hey, now it works perfectly.

Case closed.

Thanks and regards

David
