I made some effort to create a Openwrt fork for BPI-R2. I appreciate some help by changing luci configuration to match wmt wifi device. And switch config. I do this in my spare time. You are welcome to contribute issues and patches over github.

, should be last compiling versionGoals:

users 
And make it work without this wmt-tools 
Hello. Can you provide me instruction how to flash image to sdcard and emmc?
Regards
you can refer to this link, thanks.
Unfortunately file mtk-bpi-r2-SD.img and mtk-bpi-r2-EMMC.img are not exist in whole bpir2wrt directory.
May I doing something wrong?
My ‘make menuconfig’ configuration is:
Target System: MediaTek Ralink ARM
Subtarget: MT7623
Target Profile: MTK7623n BananaPi R2
Target Images: ramdisk, squashfs
Is this correct?
Regards
Sry, i am very busy right now will reply in on thursday with instructions and updates ive done, repositorie will change probably as well… sry guys for the late reply…
you have done the compile-process (imho only make) and this is done without errrors?
Yes, I have no errors.
I am working on it at the moment will post a working and highly updated new version today!
Ok, done!
I renewed the Branches and compiled a working version succesfull!
MTK-WTD wifi driver is not configured for compilation on default.
You need to checkout the repository again i removed R1 and introduced release_001 instead. Branches master develop and release_001 equal atm. INITIAL is very old dont use it!
Uboot-Script will use your entire sdcard for userdata partition which is not mounted on boot use extroot for that! So you will have a always working rootfs configuration.
on my sd card(32GB) Kernel command line generated by Uboot-Script is
earlyprintk console=ttyS0,115200 block2mtd.block2mtd=/dev/mmcblk1,65536,RootFs,5 mtdparts=RootFs:512k(mbr)ro,512k(uboot)ro,512k(config)ro,512k(factory)ro,32M(kernel),32M(recovery),256M(rootfs),31232M(usrdata) rootfstype=squashfs,jffs2
I’ve not configured script for 64gb cards !
I have configured mtk wifi to be compiled into image! Wifi can’t be configured via luci so stick to command line configuration if you like to use that dirt. Sad sinovoip, so sad!
It’s because wifi-driver needs wmt-tools for showing the wifi-interface,i’ve tried to drop them,but without any help i cannot do this
What i think could be the easiest, is to change the parsing of config files so it is compatible with openwrt.
Ok i will put some links here dont now why Datasheet : https://www.datasheetspdf.com/pdf-down/M/T/6/MT6625L-MediaTek.pdf
Some hints about chip familiy: https://forum.xda-developers.com/android/software-hacking/mediatek-wifi-bt-fm-gps-combo-chips-t3591182
Amazon EchoDot2 uses MT6625: https://www.amazon.com/gp/help/customer/display.html?nodeId=201626480
Mediatek: https://github.com/MediaTek-Connectivity/mt6620
Many Android Phones out there using this Chip drivers are diffrent to ours i think!
Can you help me kick this wmt-tools?
Current problem is: if i call init on boot,some dts-nodes seem not available. See my boot.log in wifi-patching branch
first step should be change first 2 steps (wmtloader and stp uart launcher) to automatic call so we only set mode between client and ap

No spare time left need to do different things sry I think we are working on diffrent kernel sources with diffrent patchset/ dts patches.
My problem was not the config…i get an oops after that (enable power afair)
I realy dont know how to see the difference comming from your return exclude
//return -1;
This cant be enough right?
I think i miss some of your changes there.
But i am not really into it because i am very bussy right now with diffrent things. Is there some readme or explanaition what you have done so far? On the driver side ?
Difficult for me to reverse engeneer your changes and the driver itself.
But 
to your efforts
EDIT: Ahh sry got your wifi patching branch i am kinda dump
I don’t have any docs…i tried only to move init-code from fd-trigger (wmt-loader sends a constant-value over a device-file to call init) to driver-init and skip read of config because filesystem is not mounted yet at this point
hi i looked through the echo dot 2 archive, but this seems kernel 3.18 and the wifi-driver looks like the one i used.
same function wmt_detect_unlocked_ioctl in connectivity/common_detect/wmt_detect.c which gets commands from wmt-tools over a char-device (/dev/wmtdetect)
this workflow i tried to remove so that the driver makes init on bootup (except echo because we need to select AP-Mode or Client-mode) so we can drop these wmt-tools
as for config-file…i did not read it because the options present in official (and mine) file are giving warnings so currently the file have to only exist (else kernel-crash) so i dropped the reading of it (filesystem is not ready at this point)
but i’m no driver expert, i need help for this
