yumy — Wed, 22 Nov 2023 05:28:51 GMT

My board is i.MX 8M Plus EVK,i am trying developing "speak" and "microphone" functionality

I follow IMX_LINUX_USERS_GUIDE 8.3.3 Audio Front End (AFE)

I downloaded AFE code,and try to compile then,but get error like this:

root@imx8mpevk:~/nxp-afe# make
#@echo "\nBuilding: build/obj/main.o"
aarch64-poky-linux-g++ -MT build/obj/main.o -MMD -MP -MF build/deps/main.Td -g3 -O3 -Wall -Wextra -Wstrict-aliasing -pedantic -Werror -Wunreachable-code -Wcast-align -Wcast-qual -Wctor-dtor-privacy -Winit-self -Wlogical-op -Wmissing-include-dirs -Wnoexcept -Woverloaded-virtual -Wredundant-decls -Wshadow -Wsign-promo -Wstrict-null-sentinel -Wswitch-default -Wundef -Wno-unused -Wno-parentheses -fdiagnostics-show-option -I src/ -I src/SignalProcessor -I src/AudioStream -I src/AFEUtilities -c -o build/obj/main.o src/main.cpp

| ^~~~~~~~~~~~~~~~~~

make: *** [makefile:117: build/obj/main.o] Error 1

then, i try to $sudo apt-get install libasound2-dev, but not work

root@imx8mpevk:~/nxp-afe# sudo apt-get install libasound2-dev
Reading package lists... Done
Building dependency tree... Done
E: Unable to locate package libasound2-dev

then , i modify <build directory>/conf/local.conf

CORE_IMAGE_EXTRA_INSTALL += "apt"

at IMAGE_INSTALL ,I added "libasound2-dev", but still not work

$bitbake imx-image-full

Hi @yumy,

I hope you are doing well.

To include fsl-alsa-plugins in yocto image one can add i.MX audio support by adding the below package group.

CORE_IMAGE_EXTRA_INSTALL += " packagegroup-fsl-tools-audio \
"

Thanks & Regards,
Dhruvit Vasavada
