If you cannot enter anything, the most likely explanation is that there is something wrong with your UART cable. TX works, RX does not
Please Check:
Thanks for reponse,
i have checked the solder joint, i have tried 3.3v and 5v, i have changed 3 usb ttl, but all failed
I'm suspecting that Xiaomi has updated to a new version of Uboot and prevented keyboard input.
I see a difference in putty output with topic above, my Uboot version doesn't have "You choosed 3" when the uboot automatically enters default mode:
Any advice can let me know, thanks.
I confirm that the uboot prevent input from putty, uboot not delay for input.
I have reflash SPI and success flash openwrt. SPI flash instructions I follow this tutorial: Xiaomi Mi Router 4A Gigabit Edition (R4AG/R4A Gigabit) -- fully supported and flashable with OpenWRTInvasion
I hope this helps anyone in the same situation as me.
I tried to flash my new RA75 yesterday with a CH340G board ( https://pine64.com/product/serial-console-woodpecker-edition/ ).
I had problems... connecting with 8N1, the first few seconds of the terminal output was garbage, so couldn't see the boot menu. With 7N1, I could see the whole output including boot menu, but the terminal didn't accept keyboard input. So, I thought I was stuck.
BUT. I remembered I had another USB to Serial TTL converter lying around with and FTDI FT232RL chipset ( https://www.delock.com/produkt/83117/merkmale.html ). This worked with 8N1, keyboard input was fine so I could flash OpenWRT.
So... Something is fishy with CH340G and this range extender??
hi,
i have same problem with CH340 (the terminal output was garbage).
Another USB to Serial TTL is OK
Hi,
After successfully flashing openwrt to MiWifi Range Extender AC1200, I noticed that the 5G radio is not show on Luci, do I have to do anything to enable the 5G radio or is the firmware not supporting it?
Looks like you got a different hardware revision. Can you provide a full bootlog?
I also had a strange issue today... I upgraded to 23.05.0rc2 via Attended Sysupgrade from rc1. Before the upgrade all was working well. After the upgrade both LuCI and SSH stopped working, but wifi was ok and it also continued to serve internet from the main router via LAN DHCP.
I had to reset, after which LuCI came up. I set up everything from scratch and now all is ok. Thought I'd share.
yes, this is System Log

It seems in the log I don't see any radio1 (5GHZ) appearing.
I agree that this hardware is very well built for such a cheap device.

You have a different,better wifi chip: MT7615 instead of MT7612.
Should not be hard to get supported.
How many antennas do you have?
So if there is no more uboot access, we need to get serious about finding an exploit.
I use your raw image, then I connect SPI to flash the whole raw image onto the Flash chip. So my device model RC04 will be exactly like RA75, including Uboot. And I also have 5s standby screen to be able to enter flash mode openwrt, that's how to open my uboot.
I'm wondering if I buy 5 or 10 more devices and then I flash the same raw image. I understand MAC is stored in flash memory, Do I have a duplicate mac address? I'm currently configuring the wifi mesh, I'm having some problems that I don't know if it's due to the same mac address or not, Because if the MAC is the same, there can be an endless LOOP, because the packet goes to and from the same MAC address.
I really thank you for the raw image.
I think the device has 2 antennas:
This is raw image RC04: https://drive.google.com/file/d/17znkv9UHGNbW9m0jV7hXY0Nxoh1V7RoY/view?usp=sharing
RC04 is the new version of RA75. As I see it, from 2023, RC04 will be produced instead of RA75. The two devices are identical in appearance. I randomly bought from 2 stores and got different model:
Sorry for my English not good
Yes, MAC is stored in Flash memory.
Cloning the complete flash will clone the MAC, which will give you trouble if two clones meet.
It might be possible to override the MAC in the config.
I ordered two more units directly from xiaomi. If its the new version, I will try to get them supported.
Hi,
I'm new with RA75 since 2 days.
I follow this topic to learn more about flashing.
In my case when boot menu is showing, it waits for 4 seconds.
If i press 1 or 2, it boot immediately.
After playing with it appear that when press reset button over 10 seconds launch a tftp sequenses.
I try to send openwrt.bin file but check is not ok, it wait another format or img file with good header.
To do that I configure tftp server DHCP server and so on on a Debian.
Two questions :
to flash with SPI file to upload is openwrt .bin file ?
Can somebody put picture board indicating where is eprom ? supposed is on backside ?
For guys who have issue with SPI 341A, I modified my 341A to get 3.3 Volts instead of 5 Volts, https://www.youtube.com/watch?v=C53-aqp4hbI or this one https://www.youtube.com/watch?v=-ln3VIZKKaE

hi,
you try choice 1 for load openwrt kernel
openwrt-23.05.0-rc2-ramips-mt76x8-xiaomi_mi-ra75-initramfs-kernel.bin
then openwrt run on ram => on openwrt ui menu System > update flash sysupgrade > will write flash to flash memory
openwrt-23.05.0-rc2-ramips-mt76x8-xiaomi_mi-ra75-squashfs-sysupgrade.bin
I can't, choice is always 3.
Fred
So it detectes the keystroke, but does not read it correctly?
What does it write to the log about the keycode read?
I have not tried the "TFTP from reset" method, don't know what kind of file it expects here, but he is not happy with it:
TRX MAGIC error!
Header check error!
Image verify failed!
And yes, you use the sysupgrade.bin file for direct flashing
Will check what ASCII code sent.
Edit: code ASCII sent is OK
I read about 0x200 beginning of bin file to be remove to flash, in this forum.
But don't remember kind of hardware and method.
Will also check.
Edit: Remove first 0x200 bytes doesn't work bad checksum
Edit: i will extract with SPI hardware my firmware version, and flash with your stock raw
Fred
Do you have Dump backup stock raw image from Chip Flash ?
Hi,
I will take the one you used, provided by @jdeisenh
But before flash, I will extract the one of my RA75.
Fred
