I'm going insane (Dreame D9)
TLDR Flashing via UART doesn't work (no login request "p2029_release login”)
First of all, thank you all for being here and trying to help others. I appreciate that !
I bought a used Dreame D9 and wanted to flash it with valetudo. I followed the UART guide on the website and after a lot of headaches I made it to the point "your UART connection should show a login prompt like "p2029_release login”". But the problem is that the request dosn't pop up. Everything else looks fine (to my unqualified eyes). I tried many different things and tried to find a solution in the www but i couldn't find anything :(
So after a few months of letting this project sit in the corner of my room, I decidet that I need to give it another shot. And maybe with the help of a Pro, I can get it running :)
My Setup:
- breakout PCB
- USB to TTL Serial UART Adapter (CP2102)
- USB-Sticks (first I tried it with a 128GB Stick without LED that I partitioned to 4GB FAT32, but because it didn't work I bougt a set of 8GB USB 2.0 Sticks with LEDs for way too much money)
- Dreame D9 (used and I reset it like the guide said)
- micro USB-B to USB A Kabel (connected from the PCB to my Laptop)
- Laptop running Win 11 (i know, shame on me...) with WSL2 and Ubuntu (USB connected via usbipd commands)
- Some dupont cables
Here is the output i get:
