So I checked the 3V3 power - it was at 3.3V when the TMC2209s were all removed- and went down to .2V when they were inserted! I was able to communicated with boot0 with them removed. Still couldn't download over SD card (without boot0 jumper). All this time it was the TMC2209s!! Not sure...

I double checked- the V_FUSED jumper is installed in J38 (bottom right corner of board). The 24V PSU green light is on the whole time. I think power might be the problem- I downloaded the datasheet and PCB layout. I disconnected all my motor drivers (forgot they were still plugged in). Now...

Octopus always off of 24V power. So when I take the octopus down, the pi goes down too. (both are connected to power supplies connected to 120V switch)

My pi is powered from an independent 5V power supply (which is powered from 120VAC). I was thinking maybe my PI USB is down? I tried different sockets- all the same. Still curious why the SD doesn't work either... The octopus has several green lights in the middle of the board. After...

I appreciate the help. Yes, I checked 2 usb cables- both from the same place. I might purchase one- weird part is I do get dfu feedback only for a few seconds after pressing reset on octopus. That's how I read the marlin info. Then it's gone. This is repeatable every time. I have...

I think I'm going to try to reflash the bootloader via an st-link...

After step 5 above (no SD card installed), I got: Bus 001 Device 008: ID 0bda:b711 Realtek Semiconductor Corp. RTL8188GU 802.11n WLAN Adapter (After Modeswitch) Bus 001 Device 003: ID 0424:ec00 Microchip Technology, Inc. (formerly SMSC) SMSC9512/9514 Fast Ethernet Adapter Bus 001 Device 002: ID...

Thanks again for the info. I ran your command and yes I was at version .9. I then ran your fix, now I see I am at v .11. I am unable to get the dfu of the device using lsusb command. I assume that since I can read the serial ids that the USB must be working. Any other help is greatly...

Thanks- I didn't even notice the Marlin part. How is that possible? The board definitely updated when I plugged in the SD card (all the green lights eventually turned off) so something programmed- how could it program wrong- but still reference a processor and board? This is very strange.

I'm a newbie- I followed the Voron 2.4 software installation to a btt octopus- using the setup for the stm32f407 (32k, 8 Mhz, usb on pa11,pa12..) When I uploaded via and SD card, and checked the serial id ($ls /dev/serial/by-id) I got this...
