I have the official version of Debian 12 installed on my PI4, and I use it with my Mesa 7c81, the only problem is that for some reason the SPI port is disabled from the kernel and therefore it is not possible to write a new firmware to that card . Is there a Debian 12 kernel used on the PI4 that has the SPI port enabled by default? . As the official version of the LCN page does not depend on RASPBIAN, it is not possible to enable it with raspi-config or by modifying the config file.

First of all thanks for the great work. 

is it just me or is the link on the website wrong?
www.linuxcnc.org/iso/rpi-5-debian-bookwo...23-11-17-1520.img.xz
it say: LinuxCNC 2.9.2
but when I start it it say 2.9.1 

I thought I had an older one so I reinstalled today and still the same. 
Can I upgrade linuxCNC and GMOCCAPY?
i had some issues with GMOCCAPY now compared to when I was running the PI4 that I installed years ago.
One issue I had was when I pressed the aport button during a probing script, it did not stop but the GUI changed. 
I will try to reproduce. 
I copied my old config. Can that be the issue? I thought you could

Thanks all

Linuxcncrio is another great project. The dev is a great guy.
I designed a couple of boards that connect to FPGA board available on AliExpress, so far I’ve been using Mesa firmware so it operates as a 7c81, but with some help from meister ( forum member & dev of linuxcnc-rio) I can also run his firmware as well.

Thanks very much.
You tell me severalnew things, esp re: spi.

My trusty pentium4 died recently,
after years of being on lifesupport.

luckily, I have an Rpi4 to try SPI remora MKS masahup.
(and a i686 that I can dictate this to)

(note for oother vision impairted, try nerd-dictation)

again, thanks!

Hi Linuxcnc community, 
I have installed OS in raspberry 5 and Instead of using IO expander I want to use individual ESP32+W5500 for every motor and generate step pulses. If this is possible please help me with the steps in achiving it.
Refer the image below and get what I want to achieve

Rather than using many ESP32s, I would try a W5500-EVB-Pico
shop.wiznet.eu/en/w5500-evb-pico.html
and Remora software for RP2040

That is very true.

They'll never be under $50 again. The world has changed, $50 is no longer $50.

wow, ok, in germany/amazon (not the cheapest):

Pi5/4GB = 67,84€
PI4/2GB = 47,80€

Sorry, why not ? i like the RPI's, especially via SPI

It is 150 Euro here, be it 4 or 5, i can get a full used PC for that money.

Hi @tommylight, thankyou for your insight.
Now i want to expand my inputs and outputs in raspberry pi 5, can you suggest me how to expand my i/o and if there is any solution can you also tell me how to configure HAl

Refer to this post forum.linuxcnc.org/18-computer/53136-can...g-step-pulses#304365

Now i want to expand my inputs and outputs in raspberry pi 5, can you suggest me how to expand my i/o and if there is any solution can you also tell me how to configure HAl. I do not want to use MESA board as it is expensive, can someone suggest something cheaper?

No don't use a hub.

Linuxcnc-rio is awesome, with a single WT32-ETH0 and a direct cable connection and inexpensive FPGA you can do 4 axis easily and way more.

i think he will use ethernet for wiring like with ethercat.
