Neither command you’ve tried is what the documentation says to do. The first one is missing a space, the second one is missing ls.
Curse you dyslexia!
This is why I’m not a programmer X_X
I’ll give that a shot and see if it solves my problems
edit -
i tried
ls /dev/serial/by-id/*
from the klipper FAQ.
still get the
ls /dev/serial/by-id/*
ls: cannot access ‘/dev/serial/by-id/*’: No such file or directory
You might want to check out this potential fix:
The console messages and ls /dev/serial/by-id/* output is usually due to the board being not correctly recognized by the host process on the Pi 4b+.
The typical reasons and solutions are listed here: Issues flashing the printer board
guys…i dont know if this matters, but i totally derped on the host. Its a Pi 3B+, not a 4b+…
does that matter?
I will try hooking up a different usb device and see if i can get that to recognize on that command.
im assuming that if i get the same error, it might be my pi?
ive reflashed the MCU a few times using the provided firmware, as well as my own compiled firmware. I can see on the SD card that it took the fimware.bin and its now fimware.cur, but neither seemed to do anything different.
edit -
i got my ADXL to connect to the pi!
so it is indeed my firmware that must be bad on the MCU. I’ll try compiling a new one and report back.
guys, i figured it out!
the PDF user manual the BTT provides tell you to configure for the WRONG PROCESSOR!!!
BTT says to compile for the “STM32H743”
but the board is actually “STM32H723”
after compiling for the correct processor, it works!!!
