Hi guys, I am trying to load TI bq2429x drivers into my yocto image. I face errors when at the do_compile stage. At first glance it looks to be a c program cross compilation error. I think the issue is due to not being able to link with the header files. The error I see on my screen. ERROR: bq2429x-charger-0.1-r0 do_compile: oe_runmake failed ERROR: bq2429x-charger-0.1-r0 do_compile: Execution of '/home/mohan/amlogic/build/tmp/work/mesons4_lib32_ap222-poky-linux/bq2429x-charger/0.1-r0/temp/run.do_compile.322928' failed with exit code 1 ERROR: Logfile of failure stored in: /home/mohan/amlogic/build/tmp/work/mesons4_lib32_ap222-poky-linux/bq2429x-charger/0.1-r0/temp/log.do_compile.322928 Log data follows: | DEBUG: Executing shell function do_compile | NOTE: make -j 4 KERNEL_SRC=/home/mohan/amlogic/build/tmp/work-shared/mesons4-lib32-ap222/kernel-source KERNEL_PATH=/home/mohan/amlogic/build/tmp/work-shared/mesons4-lib32-ap222/kernel-source KERNEL_VERSION=5.4.180-amlogic CC=aarch64-poky-linux-gcc -fuse-ld=bfd -fdebug-prefix-map=/home/mohan/amlogic/build/tmp/work/mesons4_lib32_ap222-poky-linux/bq2429x-charger/0.1-r0=/usr/src/debug/bq2429x-charger/0.1-r0
