MCU unable to connect
This is a really challenging issue.
I have read all the posts about the octopus V1.1 that cannot connect and say they have a configuration error and cannot connect to klippy
I have tried all the methods, new cables, new USB and I think the issue is configuration related but I can’t figure out what.
Right after I flash my board I get the “octopus pro h723 v1.1 is detected but unresponsive”, but when I connect to pi via ssh and connect to the board to identify itself it communicates that it is connected to an h723. I can supply screenshots if needed.
Not sure what to do? Should I flash something via the SSH command prompt?
I have followed the steps in printer.cig, wired it up, unwired, im about ready to get a new board but I am not convinced there is anything wrong with the board.

Ok, how can I make it flash correctly? I’ve tried every method, and swapped SD cards for a better ones, and it’s the same result… I use a separate power supply for the board rather than usb C power
Sorry to be redundant, but let's step through it one by one:
first try using SD card. Did you verify that the file on the SD card changed to firmware.cur?
I did not… and this is the first time I’ve seen that this is something that should happen… are you saying I should transfer the file, put it in the board, flash it, pull it out, and then check it on a computer?
correct
ok, i will give this a shot tomorrow, i just bricked an SD by accident, ill keep you updated
ok so, i did as the control board flashing instructions says, i am using a different a different power suorce for the board than the pi.
the firmware.bin file did not change
should i try holding the rest button and powering on at the same time? i have seen that some people do that?
ok, nevermind... now it says firmware.cur... but the board is still not detected
check board status does nothing
Is the pi connected to the internet?
yup!
ok, and you have usb C on octopus to USB A on pi? Is there anything else plugged in?
ok so, yes, and i just treied turning the board on first, and then the pi, and it detected it, however i still get this
and then this
right, now you have to go and follow the rest of the install instructions
all you did was flash the firmware, there is a lot more to do
right, but i am confused as to what is wrong, becasue i have been down this road before and never got the warning to go away, i put all the drivers in, wired the whole thing up, configured printer.cfg, and the warning never goes away
and i cant tell what step i am not doing or not doing right
