The CAN subsystem has a number of configuration options:
cdl_interface CYGINT_IO_CAN_DRIVER
This CDL interface counts the number of CAN channels
present in the system. Each driver must have an
implements command for this interface for each
channel it supports.
cdl_option CYGNUM_IO_CAN_MSG_COUNT_BASE
This CDL option defines the base number of message buffers allocated
regardless of the number of channels available.
Default value: 10
cdl_option CYGNUM_IO_CAN_MSG_COUNT_DRIVER
This CDL option defines the number of message buffers allocated per
CAN channel. The total number of message buffers allocated is
CYGNUM_IO_CAN_MSG_COUNT_BASE plus
CYGNUM_IO_CAN_MSG_COUNT_DRIVER times
CYGINT_IO_CAN_DRIVER.
Default value: 10
cdl_option CYGDBG_IO_CAN_DEBUG
This CDL option enables diagnostic output to be generated by the CAN
subsystem. This is mostly useful in debugging problems with the CAN
subsystem or in the development of device drivers.
