Hi guys!!
have some problem with my rpspi4 and linuxcnc with 7c80.
Linux pi 6.6.44-rt39 #1 SMP PREEMPT_RT Mon Aug 12 21:10:13 AEST 2024 aarch64 GNU/Linux. I spoke with a person from mesa, he told that spi is disable, i tried to enable on /boot/firmware/config.txt and change # uncomment some or all of these to enable the optional hardware interfaces

nothing happen in the board, no light come on

Looks like the SPI device driver is not loaded. maybe someone with experience with
the LinuxCNC RPI image can help with enabling that driver.
The LinuxCNC driver does work however so you should not have any issues running LinuxCNC.
The kernel SPI driver is only needed by mesaflash so unless you need to change the standard
firmware. you should be able to proceed with setting up LinuxCNC.

When running from halcm or halrun isn't it required to create a thread and add the read & write function to the thread, and then issue a start command to get anything to happen ?
And the config file is not in the same place as a normal RPi.
It is in /boot/broadcom/config.txt - this was the case for the 2023 version. And is still the case for the 2024 version. This really needs to be mentioned in the downloads section or even easier spi enable in the image.

I would probably use pncconf and create a simple step/dir configuration
for a 5i25+G540x2 and don't assign any I/O for limit switches etc
Then change the card name and driver name. This should get you a minimal
working hal/ini file set that can be edited to add the desired digital I/O
for home/limits/spindle etc

The file you have to edit is:
/boot/Broadcom/config.txt
Not /boot/firmware/config.txt
This file does not exist in Rodw’s image. You must have created the directory and file.
I downloaded Rodw’s most recent image to check. I was involved when Rod was initially making the images last year. I did a fair bit of testing.

Sorry
/boot/broadcom/config.txt
The file is the same as the official RPi image but in a different location. This is due to the patched kernel used.
