Hello.

Seems you have combined Wifi+Bluetooth device, please check this section of README: https://github.com/winterheart/broadcom-bt-firmware#notes-about-combined-wifibluetooth-devices

[lapinvb]

Thanks

wget https://github.com/khadas/android_hardware_amlogic_wifi/raw/b6709758755568e4a0ff6e80993be0fc64c77fb9/bcm_ampak/config/6255/nvram.txt
sudo cp nvram.txt /lib/firmware/brcm/brcmfmac43455-sdio.txt

but it still don't work

Hello.
Have you tried copy own NVRAM from EFI? Like that:

Some new devices are storing the nvram which is needed in addition to the firmware by the driver in an EFI variable and the Windows driver can access it (this file should be optional in the case of PCIe devices). Currently brcmfmac does not support this automatically. First mount the efi vars into sysfs:

 mount -t efivarfs none /sys/firmware/efi/efivars

The content of the nvram is in this file:

/sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113

Copy this file where brcmfmac expects the nvram, for example:

 cat /sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113 > /lib/firmware/brcm/brcmfmac43241b4-sdio.txt

Please attach whole dmesg output to see what happens with wifi driver.

[lapinvb]

sudo mount -t efivarfs none /sys/firmware/efi/efivars
mount: /sys/firmware/efi/efivars: none déjà monté sur /sys/fs/bpf
sudo cat /sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113 > /lib/firmware/brcm/brcmfmac43241b4-sdio.txt
bash: /lib/firmware/brcm/brcmfmac43241b4-sdio.txt: Permission non accordée

It seems I got any file nvram* in /sys/firmware/efi/efivars

OK, seems firmware loading possible only with brcmsmac or brcmfmac driver. Propietary wl don't provide such interface, so you cannot use Bluetooth device with wl.

You can try one of brcmsmac or brcmfmac, but I can't tell if there any support of your WiFi device. If you'll get working wifi with brcmXmac family driver, it's likely you'll get support Bluetooth too. With wl you can work only with wifi without Bluetooth capabilities.

[lapinvb]

Clear. Thanks a lot. How to change wl to brcmXmac , and go back if not working ?

[winterheart]

Sorry, there I cannot provide any advices, since I don't have such devices to research.
