GTR v1.0 + TMC5160 SPI mode - "TMC CONNECTION ERROR" #26

Closed MercadoNegro closed 4 years ago

MercadoNegro commented 4 years ago

Hello,

I bought a GTR v1.0 with 6xTMC5160, I installed just one of them to test the board and configure Marlin properly to use SPI access, and I'm getting "TMC CONNECTION ERROR" on the display, no matter what I change, if I set TMC5160 as driver I get that message.

This is de TMC status on the console:

This is not an issue in the board, it's a problem in the user. (Me), and partially something that can be improved in the manual.

To use TMC5160 I need to configure define TMC_USE_SW_SPI. This is mentioned on TMC5160 manual, but it's not mentioned in SKR GTR manual. Maybe is a good idea to drop some note on the SPI configuration part.

Thanks. Gustavo
