Remora - Rpi Software Stepping Using External Microcontroller via SPI

Hello,

Forgive me, but I am a bit new here. I have been trying to setup an RPi 4 with an Octopus 1.1 (STM32F446) and I am hitting a bit of a brick wall with trying to get a hello world going with a setup of just 3 stepper motors on a bench.

Can you please point me to a good tutorial for help please, both for understanding the basics of LinuxCNC and then how to get Remora up and running for this setup? I have installed the Flexi-Pi RPi image, that is up and running. I have flashed the Remora firmware to the STM32 using the ST CubeProgrammer utility. I have loaded the example configto LinuxCNC and I can "open" it. But then a whole lot is blanked out and I can't seem to get any response from it. I have a feeling that I missing the step where I load components and I am not sure how to do this.

Any input would be greatly appreciated.

Thanks,

Dylan

Hi Dylan,

Have a look through the docs, they should point you in the right direction.

You will need to flash the original firmware back onto the board as the Remora firmware will be loaded off the SD card with the original bootloader.
