Hi,

I tried to build the eIQ example dsp_cifar10_demo_hifi4 using xtensa xplorer, but failed with below errors.

 

F:/Softwares/Tensilica_Tools/SDK_2.9.0_EVK-MIMXRT685/boards/evkmimxrt685/eIQ/cifar10_demo/dsp/xtensa/../../../../../../middleware/dsp/nn/nnlib/lib/libxa_nnlib.a(libxa_nnlib.o):(.text.scl_tanhf+0x24): undefined reference to `__errno'


F:/Softwares/Tensilica_Tools/SDK_2.9.0_EVK-MIMXRT685/boards/evkmimxrt685/eIQ/cifar10_demo/dsp/xtensa/../../../../../../middleware/dsp/nn/nnlib/lib/libxa_nnlib.a(libxa_nnlib.o): In function `scl_tanhf':

C:\usr\xtensa\Xplorer-8.0.10-workspaces\workspace_sdk_nnlib2\libxa_nnlib\algo\ndsp\hifi4\src/scl_tanhf_hifi4.c:119: undefined reference to `__errno'

make[1]: *** [dsp_cifar10_demo_hifi4] Error 2

makefile:51: recipe for target 'dsp_cifar10_demo_hifi4' failed

 

What might be wrong during build?

Hi @yugandhar421 

 Your SDK is very old, please update to the newest one, then test it again:

https://mcuxpresso.nxp.com/en/builder?hw=EVK-MIMXRT685

SDK2.10.1, please try it, whether you still have issues or not, please also read the SDK doc related document, make sure your related software version is match the SDK release note.

If you still have questions about it, please kindly let me know.

Wish it helps you!
