BIGTREETECH TMC5160 Pro V1.1 and BIGTREETECH BTT Octopus PRO F446 on klipper: spi not working

[Nick Kozobrod]

Good day! 

I've bought BIGTREETECH TMC5160 Pro V1.1 and BIGTREETECH BTT Octopus PRO F446

When I try to test X or Y stepper klipper says Unable to write tmc spi 'stepper_x' register GLOBALSCALER

I've tried with sensorless jumpers and "diag0_pin: ^!PG6" / "diag1_pin:^!PG6 " and without - no difference

Klipper settings:

Hi, did you ever resolve this issue? I have the same problem and I have just submitted a ticket. I have the impression that some BTT Octopus Pro boards have some issue with their SPI. I had a second board that worked without issues with a pair of TMC5160HV.

The one I have now doesn't work no matter what I try. I tried 2 different types of steppers (TMC5160HV from Fysetc and TMC5160 Pro 1.1 from BTT), in hardware mode trying all the SPI channels, in software mode. Nothing.

Someone said on another forum that there was a conflict with the shared SPI with the MAX31865 putting

[static_digital_output disable_max31865]
pins: !PF8

In their configuration, but it didn't work in my case. Also, it should have been fixed in Klipper by now.

Try to reduce the speed for me works on:

spi_speed: 3500000

[Fabio]

Hi, thanks for the suggestion, I will try it. To clarify, you had the same issue (Unable to write tmc spi 'stepper_x' register GLOBALSCALER) and reducing the speed made it work?

[Fabio]

Anyway just tried and it did not work, unfortunately.

I have opened a second ticket now, as the first one was never replied (a week ago). Let's see if I have more luck with the last one.

Also, I have eventually purchased a new BTT Octopus Pro and it works without issues with the same stepper drivers I was trying to use on the first board. So, it is definitely an issue with the board.

I have also found this: https://gist.github.com/kmobs/2c151bacc1aa74bafa93ea876f50f1b6

Other people are experiencing this issue as some of the Octopus pro boards (no matter the chipset they are using) apparently have the SPI bus disconnected.

Same problem here. Any news to share on how to handle this?

[Xargan99]

same problem here.
tried a lot of things, but couldn't get rid of this error.
Any news?

[Xargan99]

After a very long try and error session I figured out that 3 out of 6 5160 were dead on arrival. The other ones work with the described config.
