Hallo Tim,

lassen sich die Updates installieren, wenn du auf der Kommandozeile folgenden Befehl ausführst?
Den Befehl kannst du z.B. auch im Terminal in der Weboberfläche durchführen.

Please double check the overlay names. In your log file the error is about spi 0 and not 5.

Nicolai

Technically this should be possible.

CAN1 is attached to spi5 with irq=25, miso=13, mosi=14, clk=15 and cs=12

https://gitlab.com/revolutionpi/linux/-/blob/revpi-6.6/arch/arm/boot/dts/overlays/revpi-connect5-can-can-overlay.dts#L137

This would result in


"spi5-1cs","mcp251xfd,spi5-1,interrupt=25,oscillator=20000000"

Hi

Does an attached monitor show any errors? Is the system only unavailable via network or also unresponsive via monitor / usb keyboard?

Nicolai

P.S: Why do you need to update the rfs via rsync?

Hi

Which image are you using? If it is the stock pi4 image, then you can enable the rtc via a custom overlay definition.

Nicolai

Yes, you can install any software you want (and is available for arm64 debian).

Hi

there are several things:

- Connect 5 is using the mcp251863 controll, thus you need to use the mcp251xfd overlay
- Connect 5 uses a 20 MHz oscillator
- You must use the correct pins and SPI interface. The controller is connected to SPI1 with pin 11 as chip select (cs1)
- Controller for spi1 ...
