When I used lsdk 20.12 ,i used dspi with mcp2518fd. I found dspi driver produces a large number of interrupt .Cpu is under heavy load,and many mcp2518fd receive data is losted. I update kernel to 5.10.9(https://source.codeaurora.org/external/qoriq/qoriq-components/linux/log/?h=linux-5.10)There have been improvements but no fundamental problems have been solved.
