Hi Christian, I have a problem about mcp251x in socketcan. I want the chip silent (do not ack can frame, and do not rise irq) at the beginning, and then shift into normal mode as soon as possible at some time. How could I achive it ? What I have tried is configure the chip in listen_only mode and then request it into normal mode. But when I request mcp251x shift listen_only mode by mcp251x_write_reg(spi,CANCTRL, CANCTRL_REQOP_LISTEN_ONLY); or mcp251x_write_bits(spi, CANCTRL_REQOP_LISTEN_ONLY, CANCTRL_REQOP_MASK); or mcp251x_write_bits(spi, CANCTRL_REQOP_LISTEN_ONLY | CANCTRL_ABAT, CANCTRL_REQOP_MASK | CANCTRL_ABAT); The chip got into sleeping mode , if I disable spi irq which the chip used, it got into sleeping mode too.
Thanks for your work and your help. Regards Robert
