Raspi 5 SPI setup

Hello everyone, im having a hard time setting up SPI on the raspi 5 running a  rpi-5-debian-bookworm image, i thought it would be relevant to ask here. For context, im trying to use some TMC5160T Pro stepper motor drives but to run them in the step/dir config i need to establish a spi connection with the drive to get the step/dir mode active. (i found this information online so i might be wrong)

I have enabled SPI in the /boot/firmware/config.txt and i have also confirmed that /dev/spidev1.0 and 0.0 are active but when i run "gpioinfo | grep spi" i only see the CS pins which (by the logic of chatgpt) is incorrect, i am assuming that i should be seeing the mosi miso and sclk pins in there too.

would love some help setting this up since its just been a headache for someone with as little experience with this stuff as i have.

 

That is fine, as long as there are entries under /dev everything is fine.

And layoff the chatgtp it's not good for your health

Yeah it doesnt really help with anything lately it just kinda is there as a last resort, i really really started disliking it but i was hoping it would atleast spit out some good info this time, but yeah thanks for the help, will take a look again tomorrow to hopefully get a stepper motor running

If you used the latest RPi image SPI will work. I tested the SPI interface using mesflah to talk to a 7c81 using the /dev/spidev.xx interface and also testing the hm2_spix driver. If either of these failed I would of rectified it before submitting the images to be put up on the downloads page.
The simplest solution was left out via chatgtp, check for the creation of the dev nodes. This has been talked about on the forum.

Any time I use ChatGPT or any of his mates, they lie. Although google's gemini did manage to write some Python code for me to connect to an API and look stuff up the other day! I was impressed.

Yeah well after some testing around it turns out that SPI wasn't an issue, the issue that stopped the drive from working was the fact that the raspi 5 couldn't provide stable enough voltage to the VIO of the drive, ive since set up 5 volts from an external power supply and it seems to be working.

Im having a different issue now where the motor itself doesn't spin, it just oscillates a bit depending on scale settings and that's about it, i have checked the motor coil connections and it seems like all the physical connections are fine but some part of the configs just doesn't let it run correctly.
