iMX6ULL-evk use Murata CYW43455 module with BUILDROOT

[SicScar]

Hi everybody, 

I'm trying to setup Murata Wifi Module CYW43455-1MW (I have the uSD-M2 Adapter kit) on my iMX6ULL-14x14-evk dev board, and I'm using Buildroot (version 2021-08-01) as build system. I easily found murata-cyw-fw inside the packages and set my dts for dev board imx6ull-14x14-evk-btwifi.dts . but I can't still see anything in the OS running. Except for the usdhc messages: 

[ 38.053537] mmc0: queuing unknown CIS tuple 0x80 (2 bytes)
[ 38.068525] mmc0: queuing unknown CIS tuple 0x80 (3 bytes)
[ 38.081181] mmc0: queuing unknown CIS tuple 0x80 (3 bytes)

[ 38.393765] mmc0: new ultra high speed SDR104 SDIO card at address 0001

Does anybody have exceprience with this module and how to it up with buildroot? 

Thanks so much

Simone

Hi @SicScar,

Unfortunate buildroot is not officially supported by NXP, you could ask on the community from Murata and see of they do, or wait for feedback that has experience on this tool.
