Debian/Ubuntu image creation

Banana Pi Router design
142

i somehow managed to compile a kernel with policy routing support

CONFIG_IP_ADVANCED_ROUTER=y
CONFIG_IP_FIB_TRIE_STATS=y
CONFIG_IP_MULTIPLE_TABLES=y                                                              
CONFIG_IP_ROUTE_MULTIPATH=y

but i still can’t use this feature.

root@bpi-r64:/# ip -4 rule
RTNETLINK answers: Address family not supported by protocol
Dump terminated
root@bpi-r64:/# ip -6 rule
0:	from all lookup local
32766:	from all lookup main
root@bpi-r64:/# ip -V ip utility, iproute2
ip utility, iproute2-6.1.0, libbpf 1.1.2

i built Debian according to the instructions:

frank-w BPI-Router-Images
./buildimg.sh bpi-r64 bookworm 6.12

Have you checked if the options are active via “build.sh config”

Have you put your kernel in the images dir and set its filename and skipkerneldownload=1?

144

yes i see builcore

145

i uploaded my file but i also later loaded my kernel onto the SD card buildimg

146

I’m not sure that it is really your kernel you have booted.

Check with “uname -a” and “zgrep -i ‘IP_MULTIPLE_TABLES’ /proc/config.gz”

In case you have builtin these options it is enough to copy bpi-r4.itb to BPI-BOOT partition. If you use install option of kernel-repo build.sh maybe filename has to be adjusted in uEnv.txt.

147

just type

    gunzip < /proc/config.gz > config.current

on your booted kernel and check if it’s what you expect

148

indeed

there’s no ‘IP_MULTIPLE_TABLES’ option here,

why didn’t it compile what i specified in the config?

what’s the correct way to install a custom config file?

149

You have changed defconfig and imported it before build? Then option pack,copy to images repo folder and important set skipkerneldownload=1 in sourcefiles_bpi-r4.conf and kernelfile to your filename as i wrote above.

150

i did

./build.sh importconfig
./build.sh config
made my changes
./build.sh

and nothing was saved, i got the default config

151 
./build.sh defconfig # add your stuff
./build.sh importconfig
./build.sh config #verify it is set
./build.sh

Use “Pack” option at the end and copy file to images repo

Or use install to install direct to your sdcard (maybe you have to modify uEnv.txt to point to the right kernel itb file). you should see file loaded in bootlog before kernel is booting.

In case of image building

skipkerneldownload=1
kernelfile=bpi-r4_6.12.55-main.tar.gz

And then run buildimg.sh (you do not need to pass kernel 6.12 because it is default).

152

thank you Frank! i’ll try it

Linux bpi-r64 6.18.0-rc1-bpi-r64 #1 SMP PREEMPT Tue Nov 11 21:20:38 CET 2025 aarch64 GNU/Linux

but noticed this in 6.18:

[   13.027503] mtk-scpsys 10006000.power-controller: sync_state() pending due to 18000000.wmac
[   13.036013] mtk-scpsys 10006000.power-controller: sync_state() pending due to serial0-0

Which is strange because wmac and btif.bluetooth (i guess this is serial0-0) are users of scpsys not depencies.

@ericwoud maybe you have already seen and fixed this? I guess it is because wmac is builtin,but driver above (mt7615e) is module and not available due to tftp boot and btif maybe also not builtin. But wonder why scpsys (driver builtin) has sync state pending…maybe only to these 2 devices?

154

That may be the case. Any difference in CONFIG_FW_DEVLINK_SYNC_STATE_TIMEOUT ?

Try setting it to y or try cmdline option “fw_devlink.sync_state=timeout”

I haven’t updated kernel on running bpi-r64 for quite some time, and am using them live. I can try some time, but not anytime soon. Now running:

[root@bpir64 ~]# uname -a
Linux bpir64 6.11.6-bpi #12 SMP PREEMPT Tue Nov  5 16:22:46 UTC 2024 aarch64 GNU/Linux

The kernel option is available since 6.4

155

nothing

i have done

./build.sh defconfig

defconfig

./build.sh importconfig

importconfig

./build.sh config

config

./build.sh

build

copy to a flash card

copy
copy723×173 33.6 KB

as a result, everything remains the same

iprule

what do i done wrong ?

156

What is the output of

uname -a

Curent uboot for arm64 boards using fit image…so you have to copy itb file,not the uImage_nodt

Per default .itb is used,in your case bpi-r64.itb if filename differs you have to set filename in uEnv.txt (R64 has old path bananapi/bpi-r64/linux/ first for uenv.txt and afair also itb and fallback root as on newer boards.

159

i don’t have another bpi-r64.itb

i only have this one

https://github.com/frank-w/BPI-Router-Linux/releases/download/CI-BUILD-6.12-main-6.12.55-2025-10-28_0916/bpi-r64.itb

and it’s stored on a flash drive /boot/bananapi/bpi-r64/linux/bpi-r64.itb

160

very strange

i have the ‘CONFIG_IP_SET=m’ option

and there is this module in the modules directory

ipset

but it’s not in the config.

noipset

i think the /proc/config.gz file appeared in my Debian based on the old config

how do i replace it with the current config?

161

I do not think you booted the kernel that you just build…
