NXP Examples for eIQ
NXP provides a set of machine learning examples for eIQ using Python3. To add a pre-configured machine learning
package group, add to your
local.conf and build your BSP:
IMAGE_INSTALL_append = " packagegroup-imx-ml python3-pip python3-requests opencv"
This will require about 1GB of additional space on the SD Card. Instructions on how to install and use the NXP
examples can be found at https://community.nxp.com/t5/Blogs/PyeIQ-3-x-Release-User-Guide/ba-p/1305998 .
ISP
The i.MX8M Plus SoC contains an Image Signal Processor (ISP). For more information see Using the ISPs on the
phyBOARD-Pollux i.MX 8M Plus documentation. This documentation is also available in German .
On-Chip OTP Controller (OCOTP_CTRL) - eFuses
The i.MX 8M Plus provides one-time programmable fuses to store information such as the MAC address, boot
configuration, and other permanent settings ("On-Chip OTP Controller (OCOTP_CTRL)" in the i.MX 8M Plus
Information
The installation of the eiq examples with pip3 requires an internet connection.

Note
On some Ubuntu 20.04 hosts, cmake uses the host's Python 3 instead of Python 3.7 from Yocto when
building python3-pybind11. (see https://community.nxp.com/t5/i-MX-Processors/Yocto-L5-4-70-2-3-0-
build-image-failed/m-p/1219619 )
As a workaround edit, the python3-pybind11 recipe by:
$ devtool edit-recipe python3-pybind11
and add to the file:
EXTRA_O= "-DPYTHON_EXECUTABLE=${RECIPE_SYSROOT_NATIVE}/usr/bin/
python3-native/python3.7"
