Hi, I am a bit wondering, but there is mrvl/sd8987_uapsta.bin referenced in the driver, but apperently it is not in the firmware git. https://github.com/nxp-imx/imx-firmware/blob/lf-6.6.3_1.0.0/nxp/FwImage_8987/sdiouart8987_combo_v0.bin seems to apparently work. How to proceed? Should the file be renamed and added to the fw git? The uartuart8987_bt.bin needed by the btnxpuart driver is there. It is just nasty to have a driver for a device but some manual matching of firmware BTW: there is also https://github.com/nxp-imx/imx-firmware/blob/lf-6.6.3_1.0.0/nxp/FwImage_8987/sd8987_wlan.bin Regards, Andreas
