Hi,
Banana Pi Lamobo R1 is a router device so it is a bit special.
Debian Buster does connect to the network.
Debian Bullseye not.
I removed to harddisk to make sure this isn’t the problem.
My last try will be the: freedombox-testing-free_latest_lamobo-r1-armhf.img
However, is this based on Debian-testing or based on Bullseye?
I could connect a serial-cable, as a last resort, is there something else I can check or compare to Buster?
Thank you
Br,
Tido
FreedomBox testing images are based on Debian testing (Bookworm). Please note that FreedomBox images use vanilla Debian kernels (which are in turn mostly upstream Linux kernels). If upstream kernel has no support for Lamobo R1 network devices, then there is very slim chance that Debian or FreedomBox has support for it.
From what you are reporting, it looks like there is a regression in the kernel sometime between Buster and Bullseye.
Thank you for your message.
By any chance, do you know who assembled the image for Buster?
So, I could ask for any secret sauce 
Images are built using automated continuous integration system using a tool called freedom-maker. The code for Lamobo R1 is here.
Lamobo R1 and the Olimex A20-OLinuXino-Lime2 share many of the same features like: A20 or 1000MBit native Ethernet.
On Buster, the A20 doesn’t use its potential, just 100MBit:
admin@freedombox:~$ ip r

10.42.0.0/24 dev wan proto kernel scope link src 10.42.0.1 metric 101
10.42.1.0/24 dev wlxaca2135cac7d proto kernel scope link src 10.42.1.1 metric 600
192.168.11.0/24 dev eth0 proto kernel scope link src 192.168.9.14 metric 100
Forgive my ignorance, maybe there is a link where I can read about this?:
Is it possible or forseen to have individual software that is not in the Debian build, like a modul for the BCM53125 PHY (7 port ethernet chip), its Distributed Switch Architecture (DSA) and Realtek rtl WiFi?
admin@freedombox:~$ lsmod | grep 'rtl\|b53\|dsa'

Or to add a patch to get much better performance on the network?
Hi @sunil ,
Sorry that it took me so long to come back after our chat in the last call, it was a busy week.
I doug out my UART cable and flashed Bullseye and started Lamobo R1.
It doesn’t apply for an IP-Address on the router, so it is impossible to reach the device without UART.

This firmware file is available in the firmware-realtek package. It is a non-free package, but probably makes sense to include it in the lamobo-r1 image (which would become a non-free image).
Thank you for you message.
I see, but this RTLwifi is not a priority I think - your introduction film explains how to connect a cable to the router, this is where the BCM53 comes into play.
The A20 has only one connection for Ethernet, but the device comes physically with 5-sockets. To serve these ports we have to enable the BCM53125 PHY (7 port ethernet chip). It is controlled/driver via Distributed Switch Architecture (DSA). Because of the ports it needs a sane network config file (which is not so difficult as I have experience from the past).
bcm53xx stmmac-0:1e: failed to register switch:
What is the next step to find out why the bcm failed to register?
Do you guys @jvalleroy , @sunil know who built the image for buster?
Network wise everything works, I even get an access point. Can you point me to the source on gitlab how the image was built?
The kernel was: vmlinuz → boot/vmlinuz-4.19.0-10-armmp-lpae
@sunil sent me the link to Gitlab: Add support for building Lamobo R1 SD card images (43ccad57) · Commits · FreedomBox / freedom-maker · GitLab the receipt how the image is built. I see no traces about additional packages like: bcm53xx but Debian Buster does connect to the network.
Not so on Bullseye, because of not registering
bcm53xx stmmac-0:1e: failed to register switch:
there is no connection to the network.
What do you think, did the debian project make some changes to this built?
Or was the build for Buster setup as a non-free image an therefore contains the necessary components?
There is no Debian package (free or non-free) with this name:
Debian -- Package Search Results -- bcm53xx
Hi James,
You’re right. I was already there, at the modules, but started to name it package.
I have searched and read.
Linux kernel modules in Debian: Modules - Debian Wiki
If you want to get a module to autoload when a device is accessed you can often add lines to /etc/modules.
b53_mdio Control the hardware - this is part of the kernel for many years
https://cateee.net/lkddb/web-lkddb/B53_MDIO_DRIVER.html
dsa_core Configure the network - this is part of the kernel for many years
https://cateee.net/lkddb/web-lkddb/NET_DSA.html
The complete error message has a hint to two files:
[ 6.139744] bcm53xx stmmac-0:1e: failed to register switch: -517 /scripts/local-bottom/mdadm: 2: /scripts/local-bottom/mdadm: rm: not found
So I searched in Buster where they are and what is inside:
./usr/share/initramfs-tools/scripts/local-bottom/mdadm
./usr/share/initramfs-tools/scripts/local-block/mdadm
They are there and they look the same in Bullseye.
Looking at the modules with the same command:
root@freedombox:/# lsmod | grep 'rtl\|b53\|dsa'
this entry is missing in Bullseye:
Module Size Used by
devlink 57344 1 dsa_core
or is this module loaded, whether or not the IP-Connection is up?
…
I tried hard for a while, than I gave up, because of missing knowledge how to solve this problem.
Now I had the idea to search at the source, DEBIAN. And it sounds like the problem is known for a while:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=986767
Comments/Problems:
Installer can’t properly bring up BCM53125 with DSA - missing DSA module tag_brcm. Also, no USB is detected.
After replacing kernel modules in installer initrd.gz from linux-image-5.10.0-5-armmp_5.10.26-1_armhf.deb
DSA properly detect and configure Broadcom BCM53125 switch, but unable to use it. Installer
try enable individual interface (wan) and disable all other, but for DSA master
interface (eth0) MUST be enabled before wan interface and stay up.
After connect USB network card - installer is able to detects network and complete the installation.
The question is, what is the approach to get this solved on DEBIAN. Any ideas or pointers are welcome, I want to get my FreedomBox
I will also join a call to talk about it, if the dialog makes it easier.
