FM350-GL and BE14 finally works on BPI-R4

Banana Pi Router design BPI-R4/BPI-R4 Pro(MT7988)
30

Actually, it’s pretty simple—just run opkg update && opkg install kmod-mtk-t7xx modemmanager-rpcd luci-proto-modemmanager pciutils mbim-utils and set the UCI configs as shown above. ※ The configuration above uses docomo (Japan) settings, so please make sure to change the APN and other settings according to your own ISP.

To be honest, if you use LuCI (the web interface), it might be even easier for beginners! The hardest part is just opening the terminal in the first place (lol). Once you get past that, it’s almost just copy-paste.

Let me know if you need any help!

root@OpenWrt:~# ubus call modemmanager info Command failed: Not found root@OpenWrt:~# ubus call modemmanager dump Command failed: Not found

These failures occur because ubus isn’t installed. Install it with:

opkg update && opkg install ubus

I had forgotten to include the ubus package in the image. My board revision is 1.1. The main difference between our setups is the firmware revision. On your system, the SIM card wasn’t recognized at first. After some trial and error with the interface settings, it began working. On my system, I got it working by setting:

network.wwan.allowedmode='5g' network.wwan.init_epsbearer='custom'

# ISP/APN configuration variables
WWAN="wwan"
APN="spmode.ne.jp"
ALLOWEDAUTH="chap"
USERNAME="spmode"
PASSWORD="spmode"
ALLOWEDMODE="5G"         # Required for sp-mode
METRIC="100"
IPTYPE="ipv4v6"
LOGLEVEL="ERR"
IP6ASSIGN="64"
MTU="1500"
SIGNALRATE="120"
INIT_EPSBEARER="custom"
AUTO="0"

# Configure the WWAN interface
uci set network.${WWAN}=interface
uci set network.${WWAN}.proto='modemmanager'
uci set network.${WWAN}.apn="${APN}"
uci set network.${WWAN}.allowedauth="${ALLOWEDAUTH}"
uci set network.${WWAN}.allowedmode="${ALLOWEDMODE}"
uci set network.${WWAN}.iptype="${IPTYPE}"
uci set network.${WWAN}.loglevel="${LOGLEVEL}"
uci set network.${WWAN}.metric="${METRIC}"
uci set network.${WWAN}.force_link='1'
uci set network.${WWAN}.ip6assign="${IP6ASSIGN}"
[ -n "$MTU" ]       && uci set network.${WWAN}.mtu="${MTU}"
[ -n "$SIGNALRATE" ] && uci set network.${WWAN}.signalrate="${SIGNALRATE}"
uci set network.${WWAN}.auto="${AUTO}"

# Initialize EPS bearer if using custom settings
uci set network.${WWAN}.init_epsbearer="${INIT_EPSBEARER}"
if [ "$INIT_EPSBEARER" = "custom" ]; then
  uci set network.${WWAN}.init_apn="${APN}"
  uci set network.${WWAN}.init_allowedauth="${ALLOWEDAUTH}"
  [ -n "$USERNAME" ] && uci set network.${WWAN}.init_username="${USERNAME}"
  [ -n "$PASSWORD" ] && uci set network.${WWAN}.init_password="${PASSWORD}"
  uci set network.${WWAN}.init_iptype="${IPTYPE}"
fi

# Attach the wwan0 device and enable IPv6
WWAN_IDX=$(uci show network | grep "name='wwan0'" | sed -n "s/network.@device\[\([0-9]\+\)\].*/\1/p")
if [ -n "$WWAN_IDX" ]; then
  uci set network.@device[$WWAN_IDX].ipv6='1'
  [ -n "$MTU" ] && uci set network.@device[$WWAN_IDX].mtu="${MTU}"
  [ -n "$MTU" ] && uci set network.@device[$WWAN_IDX].mtu6="${MTU}"
else
  uci add network device
  uci set network.@device[-1].name='wwan0'
  uci set network.@device[-1].ipv6='1'
  [ -n "$MTU" ] && uci set network.@device[-1].mtu="${MTU}"
  [ -n "$MTU" ] && uci set network.@device[-1].mtu6="${MTU}"
fi

# Apply and lock down
uci commit network
sync
mount -o remount,ro
echo "Power cycle"
34

the problem is that it works for a few seconds and then restarts itself

It seems that the modem successfully establishes a connection, but then a kernel panic occurs afterwards. Is the power supply voltage sufficient? For reference, I am using a PC-VP-BP143 AC adapter, as described here:

38

It still exhibits kernel panic using this card in pcie mode using the latest software packages.

39

Please try removing sing-box.

upd. added mtk-feed build into folder

i build 24.10.3 with dtso overlay for disabling pcie on m2 slot

dtso + eeprom be14 patch and no more tweaks

maybe its useful for someone

its stable build with stock kernel (kmod’s install’s normally)

fw_setenv bootconf_extra 'mt7988a-bananapi-bpi-r4-disable-pcie2'

then reboot and cut power → now m2 pcie disabled and port in usb mode

thank you, ive been pulling my hair out over this issue and was just about to compile my own.

This should be included by standard in wrt

42

Uploaded openwrt-mtk-feed + atc + epm +3ginfo and some kmods for basic use

fw_setenv bootconf_extra ‘mt7988a-bananapi-bpi-r4-disable-pcie2’

same procedure to disable pcie mode for modem

43

Where is the source for this overlay? Do you only set status of pci2 to disabled?

44

Yes, src - me =)

 /dts-v1/;
/plugin/;

/ {
    compatible = "bananapi,bpi-r4", "mediatek,mt7988";

    fragment@0 {
        target = <&pcie2>;
        __overlay__ {
            status = "disabled";
        };
    };
};
45

You could convert it like this (imho much more readable) and upstream it with description why this is useful

https://patchwork.kernel.org/project/linux-mediatek/patch/[email protected]/

46

Thanks for the advice, but I have absolutely no experience with this. Could I ask you to do this, if it’s not too much trouble, thank you!
