Comparison between Raspian 12 Bookworm on Raspberry Pi 4 and Raspberry Pi 5

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.

Hello,

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

There's a pre made image for the raspberry 4

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