2026-05-20[fix] components: serial_v2: preserve RT_DEVICE_FLAG_STREAM when reopening ↵Runcheng Lu
serial device - The serial_fops_open function closes and reopens the serial device,but the RT_DEVICE_FLAG_STREAM flag was not preserved across the close/open cycle. This change saves the STREAM flag before close and restores it during reopen to ensure consistent behavior. Signed-off-by: Runcheng Lu <[email protected]>

2026-05-19[drivers][serial/v2] fix missing break after -RT_EPERM when buf size is 0kaidegit
When rx_bufsz or tx_bufsz is 0, the driver returns -RT_EPERM but falls through to RT_ASSERT(rx_fifo/tx_fifo != RT_NULL). Since serial_rx/serial_tx is NULL in non-buffered mode, this triggers an assertion failure. Add break after setting ret = -RT_EPERM in the four affected cases: - RT_SERIAL_CTRL_SET_RX_TIMEOUT - RT_SERIAL_CTRL_SET_TX_TIMEOUT - RT_SERIAL_CTRL_GET_RX_TIMEOUT - RT_SERIAL_CTRL_GET_TX_TIMEOUT

2025-08-10[driver][serial] V1]: fix correct data loss logic when RX ring buffer is fullwdfk-prog
In the serial ISR (`rt_hw_serial_isr`), the previous logic for handling a full RX FIFO was flawed. When the buffer was filled, it would increment `get_index` (`get_index += 1`). This had two negative consequences: 1. It effectively discarded the oldest byte of data prematurely. 2. It reduced the usable capacity of a buffer of size N to N-1. For example, a 64-byte buffer could only ever hold 63 readable bytes after becoming full. This patch corrects the behavior by implementing a standard overwriting ring buffer strategy. When the buffer is full, the logic is changed to `get_index = put_index`. This ensures that: - When new data arrives, it correctly overwrites the oldest data. - The `get_index` is advanced along with the `put_index`, correctly marking the new start of the buffer. - The full N-byte capacity of the buffer is utilized, always storing the N most recent bytes. This change resolves the unexpected data loss and makes the buffer behavior correct and predictable.
