Help identifying WiFi chipset

[shadowswan]

Hello,

I have a CP2A which I can't get to run on the custom firmware.

user space is full of

Start load Bluetooth!!!
End load Bluetooth!!!
Can't get device info: No such device
Reset Bluetooth!!!
killall: rtk_hciattach: no process killed
killall: hciattach: no process killed

This suggests to me that the drivers for the bluetooth are not correct.
I have tried the ones in this GitHub but not got anywhere.
The BT WIFI Card Device ID is 0x9159 and below are some pictures of the board, any ideas?

Hello,

your device is NXP device

elif [ "$sdioCardID" == "0x9159" ]; then
nxpWiFiConfig=nxp/wifi_mod_para.conf
if [ $supportStaMode -eq 1 ]; then
nxpWiFiConfig=nxp/wifi_mod_para_p2psta.conf
fi
if [ -e /tmp/iw416_rootfs.tar.gz ]; then
tar -xvf /tmp/iw416_rootfs.tar.gz -C /
fi
tar -xvf /lib/firmware/nxp/iw416_ko.tar.gz -C /tmp
#insmod Wi-Fi module Driver
test -e /tmp/mlan.ko && insmod /tmp/mlan.ko
test -e /tmp/moal.ko && insmod /tmp/moal.ko mod_para=$nxpWiFiConfig
set_wifi_mac
fi

Try this version of the .hwfs firmware 2024.10.31.1827

I fell victim to the same issue, I got a new carlinkit that has 0x9159 wi-fi and all the update .img files in this repo don't support it :/ soft-bricking the wi-fi and bluetooth functions. Flashing the mentioned stock .hwfs file did fix it.

However, there is no way to root the device at this point, using files available in repository.

FWIW, the closest proper naming for this chip is in kernel terminology is [NXP] IW416, sometimes referred to as SD8978.

it's similar to the one mentioned in README Fn-Link L287B-SR (Marvell) for which the proper terminology is SD8987

config MWIFIEX_SDIO
	tristate "Marvell WiFi-Ex Driver for SD8786/SD8787/SD8797/SD8887/SD8897/SD8977/SD8978/SD8987/SD8997"
	depends on MWIFIEX && MMC
	select FW_LOADER
	select WANT_DEV_COREDUMP
	help
	  This adds support for wireless adapters based on Marvell
	  8786/8787/8797/8887/8897/8977/8978/8987/8997 chipsets with
	  SDIO interface. SD8978 is also known as NXP IW416.

	  If you choose to build it as a module, it will be called
	  mwifiex_sdio.

mainline kernel added support for SD8987 in 2019 and for SD8978(IW416) in 2023

you can also see from the older script

elif [ "$sdioCardID" == "0x9149" ] || [ "$sdioCardID" == "0x9141" ]; then

there's also SD8997. meaning the chip can randomly be one of: SD8978/SD8987/SD8997

based on

#define SDIO_DEVICE_ID_MARVELL_8987_WLAN	0x9149
#define SDIO_DEVICE_ID_MARVELL_8997_WLAN	0x9141
#define SDIO_DEVICE_ID_MARVELL_8978_WLAN	0x9159
