Hello all,
I am just despairing regarding the R64 and WiFi with the image “bpi-r64_bullseye_newatf_5.15_incomplete.img” …
I installed this on my R-64 and I can’t activate the 2.4 GHz nor the 5 GHz module in any way. It takes hours until the “WLAN0” shows up under “ifconfig -a”. The 5 GHz module I could not see so far. What is possibly wrong here? What does not work here? Should I rather go to the older version of the image?
Best regards from Berlin
i’m not sure i have tested wifi in this image as the name contains “incomplete”, it was a start for having an acutal base. i guess wifi-firmware is missing…
i wonder why it “takes hours” instead of simply “not working”.
maybe wifi driver is unstable here as i used a very early 5.15 there. try upgrading kernel to a recent 5.15.
and you have not answered to my questions here:
Hey Frank, It’s really not my style not to answer a question. I somehow missed your question. I apologize for that.

Question over Debian Bullseye image The external WiFi - Card is installed on cn25, so like your informations…
Question over Debian Bullseye image If I try “lspci” there are no output on my screen
Kernel - Version At the moment, I had the following kernel installed: 5.15.0-bpi-r64-main I don’t know, if this is a new 5.15 - Kernel or not…
takes hours instead of simply “not working” Well, the reason is, that sometimes I´ve got the WLAN0 - Interface if I reboot the router. At the moment, it is not working.
Best regards

Hey Frank,
NOW - my system is up since: 19:40:55 up 5:47, 2 users, load average: 0.14, 0.26, 0.31
AND now, I had the Interface: 14: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 00:0c:43:26:60:00 brd ff:ff:ff:ff:ff:ff inet6 fe80::20c:43ff:fe26:6000/64 scope link valid_lft forever preferred_lft forever
BUT! No IP - Adresses is bind to this Interface, etc. And I don’t know, what kind of problems that this is… Best regards

which card do you use? i know about some current limits which prevents wifi6-cards to be shown up
I use this card additional: MTK MT7615 on cn25 - Slot…
your dmesg above says you have enabled the mt7622 wmac-wifi which firmware gets loaded (which i guess is the wlan0). As it is same driver this is not missing. so basicly the card is not recognized.
if lspci shows nothing (no controllers too) i guess there is something with pcie wrong…maybe looks in dmesg about pcie mapping

As already briefly written, it happens that the system displays the WLAN0 after a very long time, before that it cannot be found.
Therefore, I do not know how to better narrow down this error… What is the reason why this is not visible immediately after restarting the router… AND! Why it does not want to bind an IP - address to it afterwards.
This is somehow not apparent to me at the moment…
It is useful to test this image: r64_buster_sd_mt7531.img for using the 5 GHz - Module?
Best regards
Z. Matthias
Yes of course you can try the older image. Afair mt7615 was working on r64.
I cannot give a fast and simple answer why it is not working.
My guess is that 5.15.0 contained a bug in pcie. You see that controller is successfully probed but port link is down.
Please mark code/logs as such by using the “<>” button for better readability.
Btw. Current 5.15.y is 5.15.40 
Thank you very much. But, how can I get the newest Kernel? Or did you have on Image with this kernel?
My kernel repo is at 5.15.33,you can get a compiled image on its releases page
Just download the tar.gz for r64, unpack the content of the folders into the right partition (maybe change name of uImage) and add a line pointing to the new kernel file in the uEnv.txt
…and I can just unpack the data “bpi-r64_5.15.33-main.tar.gz” on the router first?
And where do I find this “uEnv.txt” - file? Is a recompile of the system necessary?
no, uenv.txt is on BPI-BOOT-partition (where the uImage needs to be extracted), if none exist just create one in same folder like the uImage or in the root of this partition
modules go to BPI-ROOT like the folder in the tar-file
Well, I think this is not so easy, or?
Under </boot/bananapi/bpi-r64/linux> if found these files:
<5.15.0-main.itb> <uEnv.txt>
If I understand you right, I should install all files and /or directory: <bpi-r64.itb> <uImage_nodt>
and after them I change the <uEnv.txt> File, or?
from i installed all file to </>, or?
Ah,right,r64 uses itb file, so copy itb from tar to /boot and modules to /
Tar file contains folders BPI-BOOT (content for /boot in running system) and BPI-ROOT (/)
You can also replace existing itb (after a backup) so no change in uEnv.txt is needed
Thanks, so lot… I installed it now and reboot it. Now, the kernel is: <5.15.33-bpi-r64-main>
BUT! with <dmesg | grep -i ‘pci’ > or <dmesg | grep -I ‘mt’> the output is empty! WAN & LAN /LANBR0 is working…
I guess you missed copying the modules to /lib/modules
I guess, that I have done this…
