This kernel version contains a module for wireguard ?
imho only the basic layer for encryption was merged in 5.5, 5.4 needs wireguard manually added
Hi frank, thank you for your very good job for this development.
If I can just add 2 comments. I compiled the 5.4-main kernel and installed it on the debian buster distribution (yours).
First, on the buster debian version, the iptables command returns the following:
root@bpi-r2:~# iptables -nL
iptables: Operation not supported.
On Buster, netfilter uses the new standard module named nftables instead of iptables legacy. To make continuity on all distributions, the iptables command pointed on new nft iptables:
root@bpi-r2:~# update-alternatives --config iptables
There are 2 choices for the alternative iptables (providing /usr/sbin/iptables).
Selection Path Priority Status
------------------------------------------------------------
* 0 /usr/sbin/iptables-nft 20 auto mode
1 /usr/sbin/iptables-legacy 10 manual mode
2 /usr/sbin/iptables-nft 20 manual mode
Press <enter> to keep the current choice[*], or type selection number:
When you change the alternative to iptables-legacy, iptables command works. When I checked the kernel config, the NF_TABLES config is not available (as module or installed).
I compiled a new kernel with NF_TABLES as module and now, iptables command (based on iptables-nft) works. Since NFT is the new standard for network filtering command, I think that It is good to be activated by default on all new kernels.
Second, I have problem with fixed IP address on lan when I installed the new kernel (deb package) on R2. 9 of 10 times, ping the network gateway doesnāt work on the first boot on the kernel. When I reboot, generally the ping to gateway works.
I never have a network lost when the gateway was pinged one time, but one time I have never pinged the gateway after 10 rebootsā¦
My network configuration file:
root@bpi-r2:~# cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
# Include files from /etc/network/interfaces.d:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet manual
pre-up ip link set $IFACE up
post-down ip link set $IFACE down
auto lan0
iface lan0 inet static
hwaddress ether 08:00:00:00:00:01 # if you want to set MAC manually
address 192.168.1.46
netmask 255.255.255.0
gateway 192.168.1.254
pre-up ip link set $IFACE up
post-down ip link set $IFACE down
source-directory /etc/network/interfaces.d
Is only CONFIG_NF_TABLES needed? I guessed i had them included in defconfigā¦seems notā¦so i will add
For network issueā¦how old is your 5.4-main kernel? I fixed a wrong dts setting yesterday which may affect lan-ports

I will try with this new version.
I think (I have not tested) that CONFIG_NF_TABLES is the minimum to run nft. Personnaly I have the following configuration (depending of filter utilization):
CONFIG_NF_TABLES=m
CONFIG_NF_TABLES_SET=m
CONFIG_NF_TABLES_INET=y
CONFIG_NF_TABLES_NETDEV=y
CONFIG_NFT_NUMGEN=m
CONFIG_NFT_CT=m

is the dts-change iāve mentioned

03705c843af0 arm: dts: fix phy-mode and flowcontrol between gmac0 and port6
defconfig is the add of CONFIG_NF_TABLES
just try it out and tell me, which options are needed

which is too long for compilation.
I donāt understand what do you want to get from this line to assign it to the variable.
If I uncomment your line 161 and move it after the next line, it is compile.

it is wildcard-handling by bash because actual branch is marked with a *ā¦seems bash regex-replace cannot replace it (tried also quoting here). the line should remove the *, but fails because * in bash lists files in current directory.
i cherry-picked from another branch, so i had not tested it againā¦
Have updates branchā¦local and travis are now clean
I have started work on 5.5 (rc1)ā¦poweroff is already working in mainline.
Wifi is working in 5.5-wifi branchā¦i try to reduce modifications to watchdog-driver to bare minimalā¦have patched out many lines which are added in previous versions. It seems that only the toprgu_reset is neededā¦without it driver crashes with some timeouts
5.5-hdmi is also ready
tested kernel with wifi-changes (watchdog) on r64 and it works nowā¦i guess i can use from now same codebase for both boardsā¦need some changes to build.sh to have a better naming of uImage
have also added merged tree to test all together

Hi, Frank! Iāve just tested your latest 5.5-merged branch kernel, and it quite unstable for me: it halts randomly in about 1-3 minutes after start. No ssh, no serial terminal, only ping (over wifi). I didnāt yet figured out any action/driver which causes this behavior. My config has additional mt76x2 and sierra usm 4g modem drivers, and it works perfectly whit 5.3-wifi branch. Iāll try to test wifi-only and/or hdmi-only branch in a few days.
Hi
Any messages in log?
You can try change trgmii to rgmii twice in dts. Imho on 5.4-main i have done itā¦
Regards Frank
No messages while itās working, and i canāt check anything after it has halted.
Do you mean these?
gmac0: mac@0 {
compatible = "mediatek,eth-mac";
reg = <0>;
phy-mode = "trgmii";
ā¦
port@6 {
reg = <6>;
label = "cpu";
ethernet = <&gmac0>;
phy-mode = "trgmii";
I can try.
Rightā¦these 2ā¦removing ātā and recompile/install
Ok, give me 24 hrs. And if it makes sense i donāt use Ethernet at all.
Afaik phy-mode from dts is set here
https://elixir.bootlin.com/linux/latest/source/drivers/net/ethernet/mediatek/mtk_eth_soc.c#L2808
No error appears and trgmii is a valid mode from phymodes array
https://elixir.bootlin.com/linux/latest/source/include/linux/phy.h#L131
Basicly trgmii is same protocol as rgmii (defined as 1000baseX) but with faster clock
https://www.spinics.net/lists/netdev/msg578959.html
- 1200BaseT/Full for mt7621 only
- 2000BaseT/Full for mt7623 and mt7683
- 2600BaseT/Full for mt7623 only
With iperf3 i only reached 940mbit/s with 2 clients on lan-ports.
- mt7621A: TRGMII 1.2Gbps
- mt7623N: TRGMII 2Gbps (when connect to external mt7530 switch, the clock will be limited to 2Gbps only)
- mt7623A: TRGMII 2.6Gbps (add mt7530 switch into mt7623 package)
ps. mt7683 was renamed mt7623
Have you any idea why trgmii is not working properly? I had not even got >940mbit/s over lan-ports and it seems to be unstable for some users. Canāt reproduce yet
