Can't flash M2

[kolaa]

aqaragateway.exe is not working with Aqara M2

M2 current firmware version 3.2.7_0018_0524

When i trying to flash rootfs, i see

Goto flasher failed, try again.
Error: 'NullWriter' object has no attribute 'fileno'

If you are using M2 EU, the flash is not support M2 EU.

I had exactly the same issue with M2 CN, the aqaragateway.exe does not work for me as well with above mentioned issue.

In the end I flashed by using "gateway3utils.exe", now works fine.

See the CMD history for reference:

D:\aqara>gateway3utils.exe -x -c COM5 -t linux_0 -f .\linux_3.3.0_0017.0526.bin
Please power up gateway3!
If your gateway3 is powered up, disconnect usb cable and reconnect it.

NOT recommend to use gateway3utils to flash M2.

@niceboygithub THanks for the information. But the aqarawaygateway.exe does not work for me with error:
Goto flasher failed, try again.
Error: 'NullWriter' object has no attribute 'fileno'

Seems like a python error. Would it be possible to output more debug info?

Please plug-in USB2Uart first and have try.

Hi, I have the same error code with M1S. I can see the boot sequence from putty. Before using the tool, do we need to do something in Putty? Like, interrupt the boot sequence?

[niceboygithub]

do not open COM port with other app, like putty.

@niceboygithub I tried again with 3.3.2_0008.0605. First plugged in the USB-Serial then start the exe, same error on Windows 10:
Error: 'NullWriter' object has no attribute 'fileno'.

As a fallback and only solution, I have to use "gateway3utils.exe".

If you say this is not recommended, would it be possible to provide a command line tool like gateway3utils.exe, for M2 ? Thanks

You can test UART connection by putty first.
Make sure that the logs is output from gateway. Then power off the gateway and close the putty.
Try flash again.

I did use Putty to see log so I can confirm my UART connection is working. Same error from the .exe tool no matter what I do. I have talked to Miniknife88 who had the same issue. I’m wondering what am I doing different than you
