mt7603 on a Xiaomi 3g

[tkso1997]

Is there any news for mt7603 on a Xiaomi 3g? With openwrt drivers the 2.4ghz 7603 is basically not usable. the 5ghz works pretty good! Can we mix both drivers, for instance mtk7603 for 2.4ghz and the opensource mt7012 from openwrt for 5ghz?

[nicefile]

Yes we can . Take look here for my custom 4.14.66 build with opensource 5Ghz and close source 2.4: https://drive.google.com/drive/folders/1_WRgzpJyFr3GqQvtHelz2i_4nhI9KMyB edit: updated rom below

[tkso1997]

Cool! Is there anything I need to be prepared when installing it? Can I just do a sysupgrade or do I have to flash the partitions directly? Are you using it on your router, how is it working?

Thanks

I've did flash from breed to "OpenWRT-v18.06.1-MiR3G-ForBreed_Full.bin" . now included in g drive . Then sysupgrade to my firmware (pass is 1234567890 afair). No intensive testing done with my build but it worked with few devices connected and 2.4 Ghz was fast as it should .

[tkso1997]

Very nice! Where can I find the 'OpenWRT-v18.06.1-MiR3G-ForBreed_Full.bin‘ Its not in the drive link you posted before … ?

[tkso1997]

Thanks! Its definitely working! Is there any chance that you upgrade it to the most recent kernel? Signal strength is not the best but 2.4ghz is at least usable :). Are there any settings that I can tweak to increase the signal strength in the mtk driver?

Hello @nicefile.

Can you tell me how you mixed 2.4 and 5 ghz drivers? Another doubt: This repo is a kernel dependent? I cannot clone him and build a new firmware using latest openwrt snapshot?

Thanks.

[brainfog0]

@julianocss Also using owrt build with this mt7603 and vanilla mt7612 driver for some time. Simply excluded opensource mt7603 driver from menuconfig, added driver from this repo, added script to fetch eeprom from flash, and added module to /etc/modules.d for autobooting.

This repo contains binary drivers build for specific kernel. Latest supported is 4.14.66. So you need to checkout trunk with this version to be able to build and use it without issues

[julianocss]

Hello @brainfog0.

I made the first two steps, the firmware was built without errors. But i am afraid to flash and brick the router.

Can you help-me in these steps? "added script to fetch eeprom from flash, and added module to /etc/modules.d for autobooting." And how to checkout this specific kernel version in trunk?

Thanks. Juliano

[nicefile]

@julianocss easy: https://git.openwrt.org/?p=openwrt/openwrt.git;a=shortlog;h=refs/heads/openwrt-18.06;pg=1 look for commit just before update to 4.14.67 and that will be "kernel: bump 4.9 to 4.9.124" click tree next to it then snapshot to download tgz

[julianocss]

Thanks @nicefile, it works.

And what is these steps that @brainfog0 said: "added script to fetch eeprom from flash, and added module to /etc/modules.d for autobooting." My router is an Archer C50 V3 (MT7628AN + MT7612E). Can you help-me how to mix the drivers?

Juliano

[nicefile]

@julianocss Additional script is not needed . You need extract 512b eeprom from 'factory' (mtd3 in my case) like dd if=/dev/mtd3 of=/etc/wireless/mt7603/mt7603.eeprom.bin bs=1 count=512 .Should work from start . Try build Openwrt with nossiac modules first to see if they work . Then if not post the issue in new thread and we will see .

[brainfog0]

@julianocss sorry, was no clear enough. i meant adding this command mentioned by nicefile above to uci-defaults, so you don't need to use it manually after installing firmware. autobooting not needed for tests, i just made it later for convenience. first you want try to load driver manually with "insmod mt7603" command. if you have doubts about bricking router, try to find usb uart adapter or flash breed u-boot to your router (be careful with flashing u-boot though)

[julianocss]

Hello @nicefile and @brainfog0.

So, the steps will be: 1) Build a firmware with 4.14.66 kernel without mt76 drivers. 2) Download the file " mt7612-for-mt76x8-linux-4.14.66.ko " (this is the correct file for my router?). 3) Install manually using isnmod ( the command is only isnmod 'downloaded_file.ko' )?

Thanks. Juliano

[brainfog0]

@julianocss instead of downloading manually would be easier to add feeds from this repository to your openwrt tree (look readme.md for feeds instructions). then in menuconfig enable needed modules and plugin for luci for easier configuration, and build firmware. yes, to load module into a kernel, use command insmod 'module_name'

[julianocss]

Ok, thanks @brainfog0 .

Do you know which modules will be necessary for my router? Just mt7612? Or mt7612 + mt7628 ?

Regards. Juliano

[brainfog0]

you may try both. on xiaomi r3g mt7603 worked fine, but mt7612 crashed router. maybe on your hardware it will work better

[julianocss]

@brainfog0

Both radios (2.4 and 5 Ghz) works with only MT7603 driver?

Juliano

[brainfog0]

@julianocss nope. mt7603 - 2.4 GHz module, mt7612 - 5 GHz module

[julianocss]

Hello @nicefile and @brainfog0

I tried to compile the firmware with 4.14.66 snapshot build, but image builder do not completed and gave a lot of erros. I think that could be a problem with feeds, like luci-app-adblock, luci-app-sqm, etc. Do you have any suggestions? I thought about creating an image of stable version 18.06.1, but the Kernel version is different...

Juliano

[julianocss]

Hello @nicefile and @brainfog0

I was able to compile the firmare. The driver did not load automatically. After you manually load it and start the interface, the router restarts.

Do you have any idea what would be the problem?

I use this Openwrt commit:

https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=e3022727658166e736198529582a46abf2397ea4

Hello @nicefile

Is it working okay for you and could you share it again (link is down)?

One other thing: How did you manage to prepare the firmware that it is flashable with breed, would be very interested in it! What are the commands to turn a openwrt image into a breed compatible file?

Regards Thorsten

[tkso1997]

Hello @nicefile @all,

I compiled OpenWrt with kernel-4.14.93 your newest 4.14.93-mt7603 and the open source 5GHz mt76 driver. So far it works quite nice. Any tips on how to make the 2.4GHz a bit more responsive? Throughput is okay but its a bit laggy. Any recommendations are very welcome.

So far the combination of your closed-source 2.4GHz driver plus the open source 5GHz one seems to be the best for Xiaomi 3g.

If someone wants to try my version feel free:

[nicefile]

Hello @ALL kernel 4.14.93 from me with mt76 from 31.01 and shed_cake 15.01 I've added firmware do flash openwrt under breed then upgrade to 4.14.93 https://drive.google.com/open?id=1RWinFBxu4lmRVSFMHJIc8y8Eqrd2XSHO only need run once dd if=/dev/mtd3 of=/etc/wireless/mt7603/mt7603.eeprom.bin bs=1 count=512 then modprobe /lib/modules/4.14.93/mt7603.ko on every boot ( etc/rc.local)

[pataha]

@tkso1997 can I flash your firmware through luci upgrade page?

[tkso1997]

@pataha yes you can

Hope you can share build usually when have new build. tks you @nicefile :)

Hi how did you add the 5ghz driver? with ifconfig -a, i saw that the interface name is rai0, but under luci, it shows as ra0, i can't enable it. https://github.com/Nossiac/mtk-openwrt-feeds/issues/116

Sorry. I've trashed this project .I'ts possible to build it manually but that version will be outdated .

Thank you I have found some similar new projects but there is so much unnecessary software for me, I just need to be simple. https://github.com/coolsnowwolf/lede https://github.com/Lienol/openwrt
