MCU unable to connect
Hi. I've been working on this problem on and off since the end of last year. I've read the FAQ. I've searched the Internet. I've tried everything I can think of prior to posting.
Raspberry Pi 3A+ and Octopus v1.1 powered separately and connected to a V-Minion. Pi installs just fine (RatOS v2.0.1) with the 32-bit image. I addressed endstop wiring issues per the instructions. Initial setup is unable to flash the MCU, so following directions manually I believe I can get an image flashed on the board.
Manually navigating to the Klipper main screen and selecting Machine allows me to edit the config file for my board (select the correct include). Based on the output of the 2 ls commands (above) it looks like the Pi sees the MCU. At very least it sees there is a USB device connected (verified by output from dmesg -w). I have tried: - everything in the MCU connection issues FAQ - restarting everything in various orders - reinstalling the Pi - re-flashing the MCU - connecting in DMU mode - praying harder Any help is greatly appreciated.

Yes, I'm aware that it says MARLIN. But I swear this is from the firmware.bin file that I compiled during the prescribed manual flashing procedure in the initial RatOS setup. I swear!

But... Check Board Status never lets me advance. Klipper is red and Moonraker is green in the upper right corner.Manually navigating to the Klipper main screen and selecting Machine allows me to edit the config file for my board (select the correct include).

I swear!But it isn't 🙂 Your board was not flashed. Try a different sd card for flashing, make sure you follow the steps in the configurator.

Thanks... I've tried 3 different mSD cards. Board won't flash from SD and I cannot get it into DMU mode. I've flashed a Manta + CB1 that I recently picked up and my Pi 3A+ + SKR E3V3 also flashed just fine. I'm giving up on this board and replacing it with either a Manta m4p or the new SKRat. I really think my O is not functioning correctly and I'm tired of beating my head against it... there are better uses of my time. 😉 Thanks for the feedback!
