I would expect Mesaflash and hm2_spi to work since they use the generic SPI device driver
(as long as that's accessible and correct), but hm2-rpspi may well need to be updated
to match whatever SPI hardware the RPI5 has.

Also read today that the graphics drivers for the Pi5 won't b ereleased until kernel 6.8. I don't think that will be a big issue for CNC.

As I mentioned in my woes post I had to force mesaflash to 8 bit word length as 32 bit wasn't communicating.

I'm sorry but I didn't understand, how to install in a simple way this last version of linuxcnc on raspberry pi4 with last version of the real time kernel .
can someone help me?
Thanks

Andy tested this image for the Pi5 and found it worked ok except image colour depth was lacking.

This is just a variation of whats on the Downloads page for the 4b

I think many posts in this thread are completely unrelated to the topic I started it with.
My idea was to compare the performance of the Raspbian Bookworm (and not the Debian) on Pi4 and Pi5....

ITs difficult for users to compare the products until they have a robust installation method for the pi5. But it has been reported latency is much improved.I think many posts in this thread are completely unrelated to the topic I started it with.

[/code][/code]The results are definitely surprising [code][code]Regarding this... is it understood why the latency was so much better in the RPi 5 test, than the RPi 4? Is this purely a result of improved processor performance, or is there some other underlying reason? (And, has that result been reproduced?) Unless I'm misunderstanding, I think that latency is quite a bit better than I currently get on my 10 y.o. AMD PC, which implies I could potentially replace it (and its parallel port) directly with an RPi 5 and its gpio pins. Which I confess excites me a bit. :-) paul
Last edit: 06 Mar 2024 19:49 by pgf. Reason: text was incorrectly... tried again. and again.... argh. it's getting worse. I give up.

The OP has describe a robust installation method within the opening couple of posts. Having tested both methods for the RPi5, the Raspbian OS based method appears to be the better setup.
