Thanks, will try. Is WLAN working, and if yes, can if be configured via standard OpenWRT way ( etc/config/wireless ) ?
Embedded WLAN chip MT6625L is not working on OpenWRT yet. I have an Mediatek MT7612E mPCIE wireless card which works on OpenWRT using the mt76 driver.
Thanks for your effort. I successfully ported your bpir2 changes to the 18.06.4 openwrt distribution. I have some tips for you and for anyone interested.
- In
gen_mediatek_sdcard_imgyou assignhead=4. That is not a good idea because if you look at ptgen source code, using head=4 will make only the first1024*4*63*512bytes of partition table indexable. So the image created, althoungh working, will most likely bring to data corruption and inode indexing errors. I recommend to change its value to 255 (the maximum allowed). So you can create images up to about 7.8GB (no more because of the limitations of ptgen). - I successfully generated and installed an openwrt image for bpi-r2 emmc. Those are the steps to do it:
- Create the executable file

- After the build process you will get also an mmc.tar.gz image. Please note that during the build process you will be asked for your root password. This is needed because the emmc image needs to be mounted to be created. Why so? Because the regular root.ext4 image generated by openwrt build process is created using a tool ported from android that does not need root but will generate “buggy” images with big rootfs sizes (you will get tons of corrupted inodes that cause continuous read only remounts during usage). That’s why I recreate root.ext4 image in
Build/mediatek-mmcand I use the parameterMEDIATEK_MMC_ROOT_PARTSIZEand not the builtinCONFIG_TARGET_ROOTFS_PARTSIZE. TheMEDIATEK_MMC_ROOT_PARTSIZEcan be set to any value that fits the bpi-r2 emmc without any corruption. I recommennd keepingCONFIG_TARGET_ROOTFS_PARTSIZElow.
- To “install” the mmc image in your mmc:
- Boot bpi-r2 with openwrt from sdcard.
- From ssh console
opkg update
opkg install mmc-utils
mmc bootpart enable 1 1 /dev/mmcblk0
mmc extcsd read /dev/mmcblk0 | grep PARTITION_CONFIG
Verify that the output of last command is Boot configuration bytes [PARTITION_CONFIG: 0x48]
3. Reboot bpi-r2 with openwrt from sdcard.
4. Using scp upload in /tmp the files openwrt-mediatek-mt7623-7623n-bananapi-bpi-r2-ext4-mmc.img.gz (generated by build process) and BPI-R2-EMMC-boot0-DDR1600-20191024-0k.img.gz (download it from here)
5. From ssh console
echo 0 > /sys/block/mmcblk0boot0/force_ro
zcat /tmp/BPI-R2-EMMC-boot0-DDR1600-20191024-0k.img.gz | dd of=/dev/mmcblk0boot0 bs=1 seek=0 conv=notrunc
zcat /tmp/openwrt-mediatek-mt7623-7623n-bananapi-bpi-r2-ext4-mmc.img.gz | dd of=/dev/mmcblk0 bs=10M conv=notrunc
sync
- Switch bpi-r2 off and eject the SD card
- Reboot without sd card and you should boot from emmc
- I am currently trying to make wifi work under openwrt. I successfully built it but it actually reboots the bpi-r2 I think I wil l need frank-w help. I will post on the other thread to ask for help.

Any output on debug-uart? Have you cfg and firmware in your tree? Which kernel do you use and have you used my tree with that version
I am currently using Kernel 4.14.131. I have the cfg and the firmware both in /etc/firmware and in /system/etc/firmware. That is my debug serial port output (it is really similar to one you posted in the wifi thread: there you said that you solved the problems by patchig your dts. My dts seem very similar to the ones you have i your 4.14 kernel branch)

This seems a dts problem to me but I don’t see anything wrong in by dts. This is my mt7623.dtsi.
This is my mt7623n-bananapi-bpi-r2.dts.
Basically the only differences from the ones in your 4.14 kernel branch are the hdmi and screen related parts which I removed because in openwrt are not needed.
In the log the driver cannot get consys reset and pinctrl default but both are present i my dts. I am stcuck. My kernerl .config file seems to me similar to yours in wifi relevant parts. Thanks in advance for your help
have you replaced drivers/watchdog/mtk_wdt.c with the v2?
till this log the error “CanNot get consys reset. ret=-517” is there…some posting later we found out that i had not replaced the watchdog-driver
No I did not. I will try now and let you know. Thanks for sugggestion
Incredible!! It is working. Very weak signal but working!! Thank you very much. I will post istructions asap
You have an antenna connected? Imho not signal-strength is bad only throughput,but this is afaik a driver issue
Yes, My bad signal issue was due to missing antenna. I will perform a speed test to see the throughput. I have still a nasty issue with wifi but this is somehow caused by openwrt… After running wifi.sh that starts hostapd putting ap0 in the lan bridge, the bridge starts working fully only after some minutes. In the first minutes I can connect to the wifi but I can only receive packets from the bpi-r2 and not from the rest of the network. I will try to solve this issue, port my changes to the 18.06.5 (I ported them to the 18.06.4 now) and post my GitHub repository for anyone that needs it. Apart from the wifi, openwrt seems to be really stable and fast.
ap0 must not be in a bridge…
Why not? If it has to work as access point, shouldn’t it be bidged with the 4 lan ports? Is there some sort of driver limitation? Thank you and sorry if this is a stupid question.
I don’t know the cause,but some users reported issues after bridging ap0 to any other port.
Current driver is too dirty to find root cause…
Easiest solution is to use routing (separate subnet for ap0)…i also use this
Thank you. I will end up with your solution too
you will still experience issues looking like driver hang or non-traffic after some months of use but these are not reproducable atm
I guess these are caused by terrible driver
Using sub-network and routing works. The problem is that if I try to perform a speed test (for example the one found at the url https://fast.com/) the wifi hangs instantly and starts to work again only if I re-invoke the initialization script (wifi.sh). No message shown on dmesg. Have you ever eperienced a similar problem?
I experienced hangs like this sometimes,but no idea how to debug. You can try enabling the tc commands you find in recent versions of wifi.sh on my kernel repo or in official wiki
Works USB mass storage ?
Hi, Using an MT7623 Banapa PI R2 Ref board wit Openwrt 18.06.2
Having Issues with MT7530 Ethernet switch upon rebooting the device. Interfaces dont work . There are errors on mt7530 switch driver with timeout. Hence Network Interface dont work …
Any Suggesions
Thanks
How’s the actual status of this project? I. e. I guess, the first post is outdated - basically a good guide (the ./scripts/feeds commands missed), but the additions and alterations after 142 posts are not included.
My old buildroot has produced a running image with 18.06.2, but now I want to change to 19.07 and I don´t know, what to change in the setup to get the actual version onto the card
Edit: just started from scratch
Alterations against post #1:
git checkout openwrt-18.06-bpir2
Additions:
./scripts/feeds update -a
./scripts/feeds install -a
make runs fine
second step
make menuconfig, adding luci, openvpn and usb-storage
adding my ./files folder with my own config (procider credentails, lan and firewall settings, openvpn config)
make runs fine
third step
insert mmc support along to post #126
first run reported outdated branch and ended with error 2 (recipe for target ‘world’ failed)
second run ends w/o errors
after following the steps now I have a working version from mmc
ToDo:
persistent mac-address (currently LAN18 on my Windows)
package management lists packages partial only (opkg update no download from server, because of snapshot version?
WLAN not in focus, because the router board is behind metallic door and a RE450 works together with ARCHER C7 in mesh WLAN very well.
