Macro Definition Documentation

◆ CAN_MCAN_CALLBACKS_DEFINE

#define CAN_MCAN_CALLBACKS_DEFINE	(	_name,
		_tx,
		_std,
		_ext
	)

Value:

 static struct can_mcan_tx_callback _name##_tx_cbs[_tx]; \
 static struct can_mcan_rx_callback _name##_std_cbs[_std]; \
 static struct can_mcan_rx_callback _name##_ext_cbs[_ext]; \
 static const struct can_mcan_callbacks _name = { \
 .tx = _name##_tx_cbs, \
 .std = _name##_std_cbs, \
 .ext = _name##_ext_cbs, \
 .num_tx = _tx, \
 .num_std = _std, \
 .num_ext = _ext, \
 }

Define Bosch M_CAN TX and RX callbacks.

This macro allows a Bosch M_CAN driver frontend using a fixed Message RAM configuration to limit the required software resources (e.g. limit the number of the standard (11-bit) or extended (29-bit) filters in use).

Frontend drivers supporting dynamic Message RAM configuration should use CAN_MCAN_DT_CALLBACKS_DEFINE() or CAN_MCAN_DT_INST_CALLBACKS_DEFINE() instead.

Parameters

_name	callbacks variable name
_tx	Number of Tx callbacks
_std	Number of standard (11-bit) filter callbacks
_ext	Number of extended (29-bit) filter callbacks

◆ can_mcan_configure_mram()

int can_mcan_configure_mram	(	const struct device *	dev,
		uintptr_t	mrba,
		uintptr_t	mram
	)

Configure Bosch M_MCAN Message RAM start addresses.

Bosch M_CAN driver front-end callback helper function for configuring the start addresses of the Bosch M_CAN Rx FIFO0 (RXFOC), Rx FIFO1 (RXF1C), Rx Buffer (RXBCC), Tx Buffer (TXBC), and Tx Event FIFO (TXEFC) in Message RAM.

The start addresses (containing bits 15:2 since Bosch M_CAN message RAM is accessed as 32 bit words) are calculated relative to the provided Message RAM Base Address (mrba).

Some Bosch M_CAN implementations use a fixed Message RAM configuration, other use a fixed memory area and relative addressing, others again have custom registers for configuring the Message RAM. It is the responsibility of the front-end driver to call this function during driver initialization as needed.

Parameters

dev	Pointer to the device structure for the driver instance.
mrba	Message RAM Base Address.
mram	Message RAM Address.

Return values

0	If successful.
-EIO	General input/output error.
