@cioby23 at least it is detected on r2 :wink: and 2.4G AP-mode works (have connected to it and run ssh-connection over it), have not tested 5G mode yet

Thanks for testing Frank. I also received confirmation from @igorpec on armbian forum that it works on BananaPi R2.

I have ordered one piece of it to replace my existing MT7612e card which does does not work at the moment and it does not support 2.4G & 5G at the same time

After installing 5.4 kernel from your repository I cannot use the MT7612e card anymore. When I try to load the module it fails with an error when about the firmware. This is the output from dmesg

dmesg | grep mt76

I don’t think you can make ap on both bands at same time with this card.

Thanks for hint about mt7612 firmware on 5.4. I will check it if i have time for…

You have mt7662_rom_patch.bin in /lib/firmware? -2 is maybe “no such file”

Yes the file is there. I have installed the firmware-misc-nonfree package from Debian repositories to load the firmware.

ls -ltrh /lib/firmware/ | grep mt76
-rw-r--r--  1 root root  26K Sep  1 16:48 mt7662_rom_patch.bin
-rw-r--r--  1 root root  80K Sep  1 16:48 mt7662.bin

-rw-r--r--  1 root root  45K Sep  1 16:48 mt7601u.bin

Is it directly in /lib/firmware or in subfolder mediatek? You’ve searched with recursive flag (-r)

The previous output is only from the /lib/firmware folder. (-r) is for reverse sort (-R) is for recursive.

Indeed there is also a mediatek folder in under /lib/firmware folder. Below is its content.

/lib/firmware/mediatek# ls -ltrh

Ok,then it’s strange that file is not found…You have driver as module? log says bootup time is 7 seconds which looks like builtin and before filesystems are mounted

I have atached the full boot log dmesg.log (38.1 KB)

Strange just found the driver does not exist under the /lib/modules/5.4.2-bpi-r2-main/kernel/drivers/net/wireless folder. When I ran build.sh it created the tar.gz file and two folders BPI-BOOT and BPI-ROOT under SD folder and I unpacked the tar.gz bpi-r2_5.4.2-main.tar.gz into the rootfs which it seems does not have the mt76x2e.ko driver in it

I checked the config and it’s enabled in the kernel but file is missing.

zgrep MT76x /proc/config.gz                                         
CONFIG_MT76x02_LIB=y
# CONFIG_MT76x0U is not set
# CONFIG_MT76x0E is not set
CONFIG_MT76x2_COMMON=y
CONFIG_MT76x2E=y
# CONFIG_MT76x2U is not set

It’s not enabled as a loadable module but directly to the kernel. It says (y) instead of (m). I will try tomorrow and recompile the kernel with this driver as a module.

Hi,

[ 7.452685] mt76x2e 0000:01:00.0: Direct firmware load for mt7662_rom_patch.bin failed with error -2

And

[ 8.223316] EXT4-fs (mmcblk0p2): mounted filesystem with ordered data mode. Opts: (null)

The kernel tries to init mt76 driver and to load firmware before rootfs is mounted. Compiling it as a module should help, as all modules can be loaded only afrer rootfs is mounted. Or you can probably to try built-in a firmware to kernel

now with full bootlog it is clear :slight_smile:

Imho firmware inside kernel is only possible with initrd which is much more complex setup…or is there any easier way?

with my kernel you have no modules…also none from default. I guess it maybe a firewall issue. Maybe nftables have problems with later init of ap0 interface or similar.thats why recommend to test your kernel without modules

https://www.kernel.org/doc/html/v4.14/driver-api/firmware/built-in-fw.html

As I understood it can be built-in to Linux kernel image. Initramfs is near the same as regular modules/firmware, it can be extremely useful for various sata/sas/raid drivers or for network drivers in case of net-boot, at least it’s most widely used cases in my practice.

I have changed in the kernel config the driver to be compiled as a module instead of being directly loaded and now I see the module in the tar.gz kernel image so I think it would work fine.

I’ll test later today and upload the new kernel into the BananaPi R2. I guess that was the issue that it tries to load firmware before rootfs is mounted. Thanks for pointing this out.

UPDATE: Uploaded the new kernel with the mt76x2e module on the BPI-R2 box and it works properly now. Module and firmware are loaded properly and wifi interface is visible

Hi folks,

just a silly question, how can you apply a half sized card in a full sized place?

Thanks!

I’ve just read this topic, and couldn’t figure out! Is this card working with BPI-r2 or any BPI router board : Mini PCIe Modul QCA9880 WPEA-352ACN It’s sparklan, but actually chipset comes from Q/A.

I don’t think so…i have tested similar card and reported it works

I also would like to get some recommendation for an ac card with 802.11s. :slight_smile:

Can I put the BPI-MT7615 in a BPI-R2 (it seems so big)?

The large mt7615 (like bpi,but also other vendors too) do not fit into bpi-r2 (or you need to cut off gpio pins and need newer r2 with smaller coils).

The asiarf mt7615 card fits and works in bpi-r2.but shipping is expensive…
