  Hello, 

  I'have  build yocto boot part as described in the docs and i added an Ubuntu rootfs . 

  have copied  modules folder from modules--5.4-r0-lec-imx8mp-20221026135341.tgz into /lib/modules/ .

  I have CAN device enable but not Wifi and BLE. 

  How can i add support of the Wifi on my system ?  which s the name of the module to load with modprobe.

  Dear @O. JUD, Sorry for the delayed response. Please check the following information on your targeted device.

  For Enabling Wi-Fi on Yocto build with Ubuntu rootfs,

   

  •     In target IMX8MP check for file sdsd8997_combo_v4.bin in path /lib/firmware/nxp/
  •     modprobe mlan cal_data_cfg=none
  •     modprobe moal fw_name=nxp/sdsd8997_combo_v4.bin cal_data_cfg=none

        To check device

              =>ip link / ifconfig

   

        To scan wifi

              => nmcli d wifi list  (connect wifi antenna for better bandwidth)

   

  For Bluetooth,

      modprobe bt8xxx

   

  To check device

              =>hciconfig

   

  To scan bluetooth

              => hcitool scan

   

  
  NOTE : As per NXP to work bluetooth we need to bringup wifi first

  Hi , thanks for your reply . 

  I have another request regarding snap command. 

  Seem that it does not work on unbuntu rootfs created from debootstrap. I obtain error like :  squasfs wrong file system. 

  I have checked squaqshfs is present /proc/filesystem  but i can not use snap command. 

  Do you have an idea about what is missing ?
