Hi,

We have setup Yocto project 4.9.11_1.0.0 on a imx6qpsabresd based custom board which has murata wifi module LBWA1KL1FX-875.
We have followed the steps from murata organisation to build the output.On bootup we have to set fdt_file as imx6qp-sabresd-btwifi.dtb.
We have flashed the output files using mfgtool.
We have followed the below mentiones step on bootup.

-> setenv fdt_file imx6qp-sabresd-btwifi.dtb
-> saveenv
-> printenv fdt_file
-> fdt_file=imx6qp-sabresd-btwifi.dtb
-> bootup
-> switch to partitions #0, OK
mmc2(part 0) is current device
