fix(can): Resolve potential race condition in message transmission

2025-11-08T03:52:25Z

Setting the send status flag `sndchange` after calling the can->ops->sendmsg function could lead to a race condition if a transmission timeout occurs, resulting in incorrect state handling. This patch moves the operation of setting the `sndchange` flag to before the call to can->ops->sendmsg. This ensures that the mailbox's status is correctly marked as "sending" before the hardware begins transmission, making the driver's state management more robust and reliable, especially in handling exceptions like timeouts. Additionally, new macros for CAN filter modes have been added in dev_can.h.

feat[can]: Implement non-blocking send mechanism and enhance CAN driver functionality

2025-09-28T03:17:21Z

- Added support for non-blocking mode CAN message sending, including software ring buffer management and dynamic memory allocation options. - Improved related comments and error handling. - Updated example code to demonstrate the usage of both blocking and non-blocking sending modes, and corrected some structure field naming and macro definitions.

[components][drivers]close can irq before release fifo

2024-04-16T03:17:06Z

原来的CAN close中先释放fifo后关闭CAN中断，可能导致释放fifo后且关闭CAN中断前来CAN中断，此时rt_hw_can_isr可能在RT_ASSERT(tx/rx_fifo != RT_NULL)断言失败
