LPC1769 with Raspberry Pi5

[testservvv]

I wanted to use an SKR V1.4 Turbo in conjuction with an RPi5 but I can't get the two to talk with one another. Is it correct, that only the Remora-SPI component is working with the RPi5 but not the LPC176x one? Is it due to the BCM2853 library not being compatible anymore? If so, what changed in the Remora-SPI component to make it compatible and is that change also applicable to the LPC176x component?

Any help would be appreciated!

There are two reasons 1. The LPC176x SPI communication requires the CS line to toggle for each byte being transmitted, this feature was available in earlier versions of the Remora component using the BCM2853 library, this has not be developed or tested for the RP1 driver required for the RPi5 2. The firmware for the LPC176x has not been actively maintained and the data packet structure would need to be updated to the latest version. If #1 was solved, communication would be working, but there would be a data mismatch with undetermined behaviour.
