Re: CAN controller

Looks like I've found a work-around. I need to isolate what exactly solved it (if not all combinations here), but currently I'm running the RPI2 RT kernel (https://github.com/emlid/linux-rt-rpi), and the DMA enabled SPI driver ( https://github.com/notro/spi-bcm2708). I used the "real time priority ...

Re: CAN controller

Hi all, using a RPI2 here, kernel 3.18.12-v7+. I have a MCP2515 wired up and working with my pi here. I'm developing an application to transfer a large amount of data into the MCP2515 from the CAN bus at 500k, quickly (MCP2515 is receiving data). The application is written in c# and uses platform in...
