Building eIQ software support using Yocto Project tools with imx 6 quad

[xotjrrl]

Hello!

I want to test NXP eIQ™ Machine Learning Software Development with imx 6 quad, but error occurred when yocto build

(bitbake fsl-image-qt5)

I changed MACHINE  option  imx8qmmek -> imx6qsabreauto in local.conf file.

(when MACHINE option is imx8qmmek, bitbake is successed.)

I don't have imx8 board yet. So before get imx8, i want to try eIQ™ Machine Learning with imx 6 quad.

how can I build NXP eIQ software support using Yocto Project tools with imx 6 quad(imx6qsabreauto)?

thank you!

Hi xotjrrl@naver.com‌,

Please try adding imx6 as a compatible machine on TensorFlow recipe as only imx8qm is supported in the recipe at this time. tensorflow_1.12.0.bb\tensorflow\recipes-libraries - meta-imx-machinelearning - i.MX Yocto Project Ma... 

COMPATIBLE_MACHINE = "(imx8qm|imx6q)"

Note that imx6* processors were not tested with the eIQ release.
Let me know if it works.

Thanks,
Vanessa

I'm appreciate your fast feedback, and solved problem.

But new error is occured which is related to "python-opencv".

I tried to find "python-opencv" in my yocto directory.

I found "opencv" related bb files, but couldn't find "python-opencv".

How can I fix this new problem?

Hi xotjrrl@naver.com‌,

I just faced the same error as yours and I solved it replacing "_mx8" with "_mx6" in the following lines:

PACKAGECONFIG_remove_pn-opencv_mx6 = "python3"
PACKAGECONFIG_append_pn-opencv_mx6 = " dnn python2 qt5 jasper openmp test neon"
PACKAGECONFIG_remove_pn-opencv_mx6 = "opencl"
