What is the problem?
I am unable to connect my printer to my Raspberry Pi.
The Raspberry Pi is a Raspberry Pi 4 Model B 8gb
The printer is an Ender 3 Pro
The board for the printer is the BTT SKR Mini E3 V2.0
The LCD for the printer is the BTT TFT35 E3 V3.0
There is a antclabs Bltouch attached to the printer
The printer operates normally with marlin and prints fine
What did you already try to solve it?
I have tried 3 different power supplies: 1 with an output of 3.6 - 6.5 V 3A, 1 with an output of 5.0 V 3A and finally one with an output of 9 V 3A
I have recompiled my own marlin firmware starting from the github default base with the build environment set to STM32F103RC_btt
I have used the marlin examples for the Ender 3 Pro with the SKR Mini E3 V2.0
I changed the values SERIAL_PORT and SERIAL_PORT_2 with different combos of -1,0,1 and 2
I tried the Serial exception work around adding
I have put a strip of tape on the 5V pin of 3 different mini b usb cables (I've ordered another one just in case all the others were faulty too but it won't arrive till late next week)
I have tried disconnecting the TFT35 and using the original LCD + no LCD
I have tried using the most up to date version of Octoprint and Octopi (the 'logs indicate a slightly older version as this is the one that the imager installed on them.
/var/log/webcamd.log, syslog, dmesg, ... no 'logs, no support)
Have you tried running in 'safe mode?
Did running in 'safe mode solve the problem?

I have added apostrophes to some words as Markdown was auto hyperlinking them and I wasn't able to post.
