X40 Ultra fastboot problems

[MrTux86]

Are you already using Valetudo?

Yes, for a long time

Your questions

Hi @ALL.
I have been using Valetudo for quite some time on my Dreame L10 pro.
Worked like a charm... at least until the robots memory died ;)

I now "upgraded" to the X40 Ultra and tried to work through the guide to get valetudo working.
I managed to connect the robot to debian 12.10 live and get the config string. (also requested and downloaded the image files from dustbuilder site).
But I'm somehow not able to download the three dustxXXX.bin files.
If I send the command "fastboot get_staged dustx100.bin" I can see: "Uploading 'dustx100.bin'....." and a blinking cursor at the end but that's it... no okay, no finished... not even a disconnect after the 160s.

Anyone got an idea?
I didn't want to "force" try to up/download the created image to root the robot. Didn't want to brick it, if it doesn't work.

I connected the robot with a self build USB cable. (working on getting the PCB breakout board).
Could it be, that getting the config value works but as soon as more transfer occurs, the connection just dies?

You've discovered why the docs tell you to use the PCB.
The answer here is signal integrity or lack thereof
