I've been using the mcp251x driver, and I'm getting a "write: No buffer space available" error. That is what cansend prints after I get into this state. I have a user space program that is reading and writing about 20 time a second.
I see this with both the work-queues and threaded interrupt version. In the threaded interrupt version unloading and reloading the mcp251x module fixes the problem. In the work-queues version just disconnecting the can device and re-connecting it fixes it. Is there some way to purge/flush the buffer? Is there some other work around sort of reloading the module? thanks, Paul
