Building Firmware for Upload returns Error about TMC2208

I am trying to build and upload Marlin Firmware 2.0.8 Release.
I Downloaded Marlin 2.0.8 Release from here [marlinfw.org]
and the configuration File from here [github.com].
I am useing VSCode with PlatformIO and Marlin Auto Build. I am trying to Build from config/examples/Geeetech/A10T/StockLCD

I want to use the Firmeware for my Geeetech A10T with a GT2560 V4.0 Motherboard and 6x TMC2208 Stepper Motors and a 3DTouch.
In the Printer the GT2560 is a Version 4.0, in the Firmware it says GT2560 V3.0. But i allready learned there is no difference in Pin Layout.
I changed the Numbers of Extruders from 1 to 3. Returned Error. So i undid this.

// @section extruder

// This defines the number of extruders
// :[0, 1, 2, 3, 4, 5, 6, 7, 8]
#define EXTRUDERS 1 [Geeetech A10T has 3 Extruder/Filament Guides and one Nozzle/Frontend.]


I modifyed the following Section by changeing the Steppermotors that i am using now. Original are A4988 to TMC2208. I undid because of Errors in VSCode:
/**
* Stepper Drivers

* These settings allow Marlin to tune stepper driver timing and enable advanced options for

* A4988 is assumed for unspecified drivers.

try changing lines that look like this:
#define X_DRIVER_TYPE TMC2208 changed from A4988

to this:
#define X_DRIVER_TYPE TMC2208 //changed from A4988

That will make the old A4988 driver type a comment, rather than part of the compiled code (which won't work).

Sorry but that was just an Info about what i did. "changed from A4988" is just a comment here in the Message. This did not appear in VSCode/PlatformIO. I didnt mean to confuse.

In the Meantime i tryed again from the scratch. Downloading Marlin 2.0.8 release and Configuration 2.0.8 release. Copied example configuration into Marlin Folder replaced existing configuration.h.
Opened Folder in VSCode. Went to configuration.h. Modified Sections and Entrys.

Changed the Stepper to TMC2208.
Checked for Errors.
Did changes according to the Errors.
But i cannot do anything about the #error "TMC2208 or TMC2209 on X requires X_HARDWARE_SERIAL or X_SERIAL_(RX|TX)_PIN."

The error is "#error "TMC2208 or TMC2209 on X requires X_HARDWARE_SERIAL or X_SERIAL_(RX|TX)_PIN."

Which is correct for TMC2208

setting TMC2208 you are telling Marlin you want to use the TMC2208 in UART mode which requires serial lines.
This motherboard does not support UART mode. So there are no pins defined in the boards pins file setup for (X|Y|Z|E)_HARDWARE_SERIAL or (X|Y|Z|E)_SERIAL_(RX|TX)_PIN
If this is what you are really after you need to add external wires between the TMC2208 Uart pins and your motherboard. then you need to add the pins you used to Marlin. See ramps pins file for examples.


What your probably doing is running the TMC2208 in standalone mode, where they don't use UART and don't need serial ports configured.
In which case you should set your stepper drivers to TMC2208_STANDALONE not TMC2208

Ahhhhhh...now that makes Sense.
Thank you Dust.
I think i understand now.


I will test that right away.
May i ask for some suggestions for Mconfig besides Marling Config page?

Indeed TMC2208_STANDALONE solved the Issue.

Thank you again Dust.

On to the next Issue.
