qmi_install.sh incompatible with 5.4.51-v7l+ kernel

[mldichter]

qmi_install.sh can only accept 4.14 and 4.19, but the kernel has changed.

The “Getting Started” followed by the “QMI Interface with Cellular IoT App Shield” do not work as of this review. Step 10, “Run the installation file. Make sure the module is disconnected before running the installer script. sudo ./qmi_install.sh” results in “Driver for 5.4.51-v7l+ kernel not found” output.

The problem comes from the qmi_install.sh file in these lines,

case $(uname -r) in
    4.14*) echo $(uname -r) based kernel found
        echo "${YELLOW}Downloading source files${SET}"
        wget https://github.com/sixfab/Sixfab_RPi_3G-4G-LTE_Base_Shield/raw/master/tutorials/QMI_tutorial/src/4.14.zip -O drivers.zip
        unzip drivers.zip -d $INS_DIR && rm -r drivers.zip;;
    4.19*) echo $(uname -r) based kernel found 
        echo "${YELLOW}Downloading source files${SET}"
        wget https://github.com/sixfab/Sixfab_RPi_3G-4G-LTE_Base_Shield/raw/master/tutorials/QMI_tutorial/src/4.19.1.zip -O drivers.zip
        unzip drivers.zip -d $INS_DIR && rm -r drivers.zip;;
    *) echo "Driver for $(uname -r) kernel not found";exit 1;
esac

When will the installation files, or at least the instructions, be updated? As an alternative, can a compatible raspberry pi image be posted? If not, this product is not of much use anymore.

Just ran into the same issue getting the base hat up and running. While I hope they can update their drivers to work with the newest kernel, you can use the following command to revert to 4.19. This is from step 6 in the QMI install guide.

sudo rpi-update 985bc5353e4f5fe5a11c8b6c4c646dc7165bbc21

Thanks. I should also note that I was following the instructions for the Raspberry Pi 4, which skips steps 4-7 in the instructions.
