Install SDK to communicate with quectel AG15

Hi,

I got one quectel AG15 chip, and i’m trying to communicate with it using the DART-MX8M board from variscite.
For that i am trying to integrate the sdk used to communicate with the chip in a yocto build.

For the build i have quectel_cv2x_sdk_23700_20190318.
From that folder i’m copying all the files in the patch 4.x to the yocto kernel used.
and create one yocto layer with all the files in the folder imx8_sdk with this bb file:

SUMMARY = “Simple helloworld application”
SECTION = “examples”
LICENSE = “MIT”
LIC_FILES_CHKSUM = “file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302”

SRC_URI += “file://etc”
SRC_URI += “file://lib”
SRC_URI += “file://sbin”
SRC_URI += “file://usr”

do_install() {
install -d ${D}/etc
cp -r ${WORKDIR}/etc ${D}/etc
install -d ${D}/lib
cp -r ${WORKDIR}/lib ${D}/lib
install -d ${D}/sbin
cp -r ${WORKDIR}/sbin ${D}/sbin
install -d ${D}/usr
cp -r ${WORKDIR}/usr ${D}/usr
}

FILES_${PN} += “/etc”
FILES_${PN} += “/lib”
FILES_${PN} += “/sbin”
FILES_${PN} += “/usr”

because when i try to copy the folders to the root in a already build yocto OS, it don’t works.
Anyone knows whats the problem or anyway to install the sdk?

quectel AG15 SDK needs to use the recommended compiler;

Do you have more detail log ?
