Xiaomi mi wifi 3 support

im very interested in this router are there any hopes for there being support soon?
it has the same hardware as the nano

So looks like the "mi wifi mini" firmware is compatible.

While looking at https://wiki.openwrt.org/toh/xiaomi/mir3 and https://wiki.openwrt.org/toh/xiaomi/mini, there're no instructions on how to write the LEDE firmware onto wifi 3 router. The regular "mini" instructions state:

If you find a line "OS1" go ahead with flashing:  # mtd -r write <firmware-image you downloaded> OS1

There's no "OS1" partition on the mini 3 tho:

root@XiaoQiang:~# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 08000000 00020000 "ALL"
mtd1: 00040000 00020000 "Bootloader"
mtd2: 00040000 00020000 "Config"
mtd3: 00040000 00020000 "Bdata"
mtd4: 00040000 00020000 "Factory"
mtd5: 00040000 00020000 "crash"
mtd6: 00040000 00020000 "crash_syslog"
mtd7: 00080000 00020000 "reserved0"
mtd8: 00400000 00020000 "kernel0"
mtd9: 00400000 00020000 "kernel1"
mtd10: 02000000 00020000 "rootfs0"
mtd11: 02000000 00020000 "rootfs1"
mtd12: 03600000 00020000 "overlay"

Do I run: mtd -r write <firmware-image you downloaded> rootfs1?

Or how can I find which partition to write LEDE firmware to?

I was very short on time and looks like wifi 3 uses NAND while wifi mini does not, so I ended up flashing Padavan's firmware.

Yes,it uses NAND.
That is only difference

Is there any plan to support this device?
By the looks of it it already does use OpenWRT, but it "calls home" to 2 Chinese domains, so I do not plan to use the original firmware.
For now it just sits in my network-bin box...

Looks like the partitions (or at least their names) are different too.

Yes,everything about flash memory is different.
That is only difference,unfortunately I do not know ho do make a proper DTS for it.
It would be great to have LEDE for it since it is great router

xiaomi router 3 flash lede must upgrade uboot,but no have supported nand flash uboot now.
if you use spi flash insted the nand flash ,it supported.
I'm build a nand flash firmware,but I'm not tested,because my router's nand uboot it's bad,
I'm used spi flash now.

Stupid question. The router apparently does run OpenWRT - I flashed "dev" version of the firmware and using ssh I've seen the file structure.
Now, how big of a rework would it be to take the mi wifi mini partition and "mix-and-match" it with the Xiaomi version?
I really do not want my home router to call home...

This PR for Mi Router 3G looks like it could be modified to also support R3
https://github.com/lede-project/source/pull/1299

I have built LEDE images for R3,but I cant test them.
If anyone wants to try here they are:
https://drive.google.com/drive/folders/0B1VOQQ-_EIXKcmVHOEJpbmFKNGs?usp=sharing

Instructions should be the following:
Installation through telnet/ssh:

copy lede-ramips-mt7621-mir3g-squashfs-kernel1.bin and lede-ramips-mt7621-mir3g-squashfs-rootfs0.bin to usb disk or wget it from LEDE download site to /tmp
switch to /extdisks/sda1/ (if copied to USB drive) or to /tmp if wgetted from LEDE download site
run: mtd write lede-ramips-mt7621-mir3g-squashfs-kernel1.bin kernel1
run: mtd write lede-ramips-mt7621-mir3g-squashfs-rootfs0.bin rootfs0
run: mtd erase kernel0
run: reboot

As always I am I no way responsible for any damage that can incurr

tried the image and did follow the commands. However boot not possible :frowning:

@dgiese I will look into the log today and try to fix it.
Can you try booting kernel image and then sysupgrading?

Cannot do anything at the moment. As Xiaomi disables the console write and the reset button for recovery does not work, i have to wait a few day until i get access to a nand flasher.

Yeah,I completelly forgot that they disable console by default

Your nand driver is not starting, show me DTS that you have made

To enable console run these commands while in u-boot
setenv uart_en 1
saveenv
You can also restore from tftp procedure

You can find my R3 branch here:

and DTS is here:

You've forgot & here, should be &nand

And you should put it outside of main brackets, it's a seldom node, not within any other, like this one


Put that &nand node just before &gpio0
