Enabling eIQ for i.MX6QP

Hi, I'm new in ARM and I have a iMX6QP SABRE board.

I'm following https://www.nxp.com/docs/en/nxp/user-guides/UM11226.pdf  with little modification as below:

(I'm trying in VirtualBox with ubuntu 18.04.3 LTS.)

--------------------------------------------------------------------------------------------------

from :

EULA=1 MACHINE=imx8qmmek DISTRO=fsl-imx-xwayland source ./fsl-setup-release.sh -b buildxwayland

PACKAGECONFIG_remove_pn-opencv_mx8 = "python3"
PACKAGECONFIG_append_pn-opencv_mx8 = " dnn python2 qt5 jasper openmp test neon"

PACKAGECONFIG_remove_pn-opencv_mx8 = "opencl"

to :

EULA=1 MACHINE=imx6qpsabresd DISTRO=fsl-imx-xwayland source ./fsl-setup-release.sh -b buildxwayland

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

PACKAGECONFIG_remove_pn-opencv_mx6 = "opencl"

(I already modified the tensorflow_1.12.0.bb with COMPATIBLE_MACHINE = "(imx8qm|imx6q)")

--------------------------------------------------------------------------------------------------

And I ran bitbake with this settings:

But I got some errors in configuring armnn as below:

--------------------------------------------------------------------------------------------------

I thought the problem came from lack of setting for pthread and valgrind.

So I tried to add -lpthread option in toolchain.make and make symbolic link of valgrind to sysroot like below,

but it didn't work :

--------------------------------------------------------------------------------------------------

for valgrind:

sudo ln -s /home/s1/fsl-arm-yocto-bsp/build-xwayland/tmp/work/cortexa9hf-neon-poky-linux-gnueabi/valgrind/3.13.0-r0/image/usr/include/valgrind /home/s1/fsl-arm-yocto-bsp/build-xwayland/tmp/work/cortexa9hf-neon-poky-linux-gnueabi/armnn/19.02-r1/recipe-sysroot/usr/include/valgrind

sudo ln -s /home/s1/fsl-arm-yocto-bsp/build-xwayland/tmp/work/cortexa9hf-neon-poky-linux-gnueabi/valgrind/3.13.0-r0/image/usr/lib/valgrind /home/s1/fsl-arm-yocto-bsp/build-xwayland/tmp/work/cortexa9hf-neon-poky-linux-gnueabi/armnn/19.02-r1/recipe-sysroot/usr/lib/valgrind

for pthread:

set( CMAKE_C_LINK_FLAGS " -lpthread -march=armv7-a -mfpu=neon -mfloat-abi=hard -mcpu=cortex-a9 --sysroot=/home/s1/fsl-arm-yocto-bsp/build-xwayland/tmp/work/cortexa9hf-neon-poky-linux-gnueabi/armnn/19.02-r1/recipe-sysroot -Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed " CACHE STRING "LDFLAGS" )
set( CMAKE_CXX_LINK_FLAGS " -lpthread -march=armv7-a -mfpu=neon -mfloat-abi=hard -mcpu=cortex-a9 --sysroot=/home/s1/fsl-arm-yocto-bsp/build-xwayland/tmp/work/cortexa9hf-neon-poky-linux-gnueabi/armnn/19.02-r1/recipe-sysroot -O2 -pipe -g -feliminate-unused-debug-types -fdebug-prefix-map=/home/s1/fsl-arm-yocto-bsp/build-xwayland/tmp/work/cortexa9hf-neon-poky-linux-gnueabi/armnn/19.02-r1=/usr/src/debug/armnn/19.02-r1 -fdebug-prefix-map=/home/s1/fsl-arm-yocto-bsp/build-xwayland/tmp/work/cortexa9hf-neon-poky-linux-gnueabi/armnn/19.02-r1/recipe-sysroot= -fdebug-prefix-map=/home/s1/fsl-arm-yocto-bsp/build-xwayland/tmp/work/cortexa9hf-neon-poky-linux-gnueabi/armnn/19.02-r1/recipe-sysroot-native= -fvisibility-inlines-hidden -march=armv7-a -mfpu=neon -mfloat-abi=hard -mcpu=cortex-a9 --sysroot=/home/s1/fsl-arm-yocto-bsp/build-xwayland/tmp/work/cortexa9hf-neon-poky-linux-gnueabi/armnn/19.02-r1/recipe-sysroot -fopenmp -Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed" CACHE STRING "LDFLAGS" )

(Actually, the error messages for pthread are changed, but finally fails :

Determining if the function pthread_create exists in the pthreads failed with the following output:

> Determining if the function pthread_create exists in the pthreads passed with the following output:)

--------------------------------------------------------------------------------------------------

Eventually, all the compile process excepts armnn, onnx, and tensorflow were succeeded.

(armnn : error in configure, rest : error in compile)

How do I avoid these problems? 

Or, is it impossible to enable eIQ for iMX6?

Thanks in advance.

Hi,

eIQ is supported only for i.IMX8 family of SoCs.

Thanks for reply. 

Then, can I run tensorflow-lite without using eIQ?

Hi,

recently, I posted an article about using Tensorflow on i.MX6 SoC's:

SBCX-TN-005: Using TensorFlow to implement a Deep Learning image classifier based on Azure Custom Vi... 

Maybe it is useful for you to run Tensorflow Lite on the i.MX6QP.
