1 year ago Are you sure "SERIAL_PORT 2" is correct? I have mine defined as 1 and if I recall correctly with 2 it did not work. I could be wrong, but I thought 2 is for motor controller communication. Just a guess on my side. Before trying, I recommend checking against other ready to use configs, which you should find easily in the wilds.

1 year ago On the BTT SKR MINI E3 V2.0 there are 4 serial ports -1 is the usb serial cable 1 is the serial port on the exp 1 header (you do not want to enable this when you have a CR10_STOCKDISPLAY which is also plugged into exp1) 2 is the serial port on the TFT header 4 is the serial port used to talk to the TMC2209's

1 year ago Tested on Current bugfix
With these exact configs (from the marlin Configurations) configs.zip
The screen and board start up as expected.
I suspect the issue is that you selected STM32F103RE_btt, without checking what CPU you have on your controller
If the controller has a STM32F103 RET6 then you use STM32F103RE_btt but if it has a STM32F103 RCT6 Then you must use STM32F103RC_btt

1 year ago So it seams that i was using the incorrect CPU but unfortunately it did not solve my problem...
My problem is still there. I went through and tried all 4 variants of the btt auto compiler for RCT6. btt, btt_maple, btt_USB and btt_USB_maple without any success.
i even downloaded the "config.zip" you uploaded with no success.. Tried it with btt and btt_maple and no screen.. so the problem seam to still be there..

1 year ago Since I have tested this hardware combination, twice now, and it still works as expected that leaves hardware..
So perhaps you have miss identified your motherboard or lcd type?
regardless, this is not a bug, so this is a support matter

Bug Description
Hi, Downloaded latest main version and configured setting and tried upgrading my printer (Ender-3) I ran autobuild marling in VS Code using "STM32F103RE_btt" as i have upgraded my motherboard to BTT mini E3 v2.0. After flashing my board using SD card i get blue screen on my display and nothing more after 30-40 seconds..
I then tried running the same settings but using latest bugfix but same thing.. Tried connecting using my octoprint and checking to see if i can controll it without my screen but no success, cant even gett connection..
I have also tried compied using btt_USB with no success, still blue screen..
I have now tried the outdated btt_maple build and now i gett a screen. Unfortunately when pressing my wheel i seem to gett an error and my printer freezes up and reboots.. (same on main and bugfix) Anyone seen this before?
Thanks in advance!
