Hei
Thanks for reply and input.
The reason is simple I have a raspberry pi and a touch screen and it is tempting a option that has small footprint. It just sounds so rlegant to have a small box with touch screen to control my machine.

I didnt buy any mesa card yet but i am exploring different options. My current setup is still ok and working but i need to change something soon. Last pc I had was so bad that on the end my motors was blocked in the middle of operation.
I guess running thru parallel port is not option for the future.

My personal problem is that i am more of mechanical guy and each time i need to do something with system i forget what i did and need to kind of learn things again
But there is usually a lot information on this forum and community is very helpful and active. At the momet i am learning about ppf setup and mesa cards.

Grateful for answers here.

Don't ask me, I just built the installer 
I think you are supposed to use this linuxcnc.org/docs/2.9/html/drivers/hal_gpio.html

Everything works fine for Debian. Thank you!
But when I want to use Linucnc. in the process to configure Linuxcnc, I can't find the the GPIO drivers in the interfaces or everywhere.
What can I do?
Cordially.

Should I get 4gb or 8gb RAM ?
For linuxcnc.

Also, when you run it up please type
sudo menu-config
to change locale, time zone. password and a few other settings

Just for completeness it's a PCIe x1 slot, not PCI.

Mesa SPI & Ethernet work fine, a 6i24 or 6i25 might work .

It should work. The benefit here would be the PCI slot.. If someone were to make hardware for it. GPIO step generation is still probably jittery

Finally got it downloaded and ran per instructions but the sudo dpkg -i linux-image ... exited with errors - some of this looks like it might be related to raspberry PI but before I execute this, I thought it best to ask if this is "normal". Please see attached.

Knowing how much blood, sweat & tears Rod has put into the project, maybe you'd like to donate a RPi5 so Rod might be able to support it quicker.

why not , you can allready boot RPI4 (CM4) from NVMe

Looks good, wonder if it'll support NVMe boot .

Here we go again and now it might have the power to actually work? Key features include:

• 2.4GHz quad-core 64-bit Arm Cortex-A76 CPU
• VideoCore VII GPU, supporting OpenGL ES 3.1, Vulkan 1.2
• Dual 4Kp60 HDMI® display output
• 4Kp60 HEVC decoder
• Dual-band 802.11ac Wi-Fi®
• Bluetooth 5.0 / Bluetooth Low Energy (BLE)
• High-speed microSD card interface with SDR104 mode support
• 2 × USB 3.0 ports, supporting simultaneous 5Gbps operation
• 2 × USB 2.0 ports
• Gigabit Ethernet, with PoE+ support (requires separate PoE+ HAT, coming soon)
• 2 × 4-lane MIPI camera/display transceivers
• PCIe 2.0 x1 interface for fast peripherals
• Raspberry Pi standard 40-pin GPIO header
• Real-time clock
• Power button

raspberry pi 5 coming soon!
