Hi Andreas,

Excellent point. Please note, that btmrvl_sdio needs an SDIO BT FW. So, mrv=
l/sd8987_uapsta.bin should preferably be a such a combo FW.

Unfortunately, to my knowledge, none is available publicly. Also, after the=
 acquisition of Marvell IoT, NXP regrettably decided to develop mwifiex dow=
nstream, here https://github.com/nxp-imx/mwifiex.

It is what it is. Due to licensing, the FW binary should come from NXP. I c=
annot arrange that.

Kind regards,
Tamas
