Imx-uart 2020000.serial: rx fifo overrun
WebAs the board under test is equipped with iMX6UL revision 1.0, active oscillator is required to implement the fix described by errata ERR009455. Typical consumption of this oscillator is about 20mW. Future revision of the board will be populated with silicon revision 1.1 or newer. Thus active oscillator will be removed. WebNov 22, 2024 · In a serial RS-232/UART transmission from a µC to a PC, I am having problems with data loss (FIFO overruns) after wake-up of the PC. "PC" is the receiver, a ThinkPad T400 laptop running "Ubuntu 20.04.5 LTS". "µC" is the sender, a bare-metal micro-controller (AVR ATmega168) connected via MAX232* to the PC.

WebAug 16, 2006 · For fun, have you tried playing with the rx FIFO trigger level in the 16550A entry in drivers/serial/8250.c ? You could try replacing UART_FCR_R_TRIG_10 (8 char trigger) with UART_FCR_R_TRIG_01 (4 char trigger) or even UART_FCR_R_TRIG_00 (1 char trigger). That creates more interrupts, but allows more time to activate the ISR before overrun. WebSep 1, 2005 · A. Overruns appear in the output of the show interface Serial 0 command when the serial receiver hardware is unable to hand received data to a hardware buffer because the input rate exceeds the receiver's ability to handle the data. This occurs due to a limitation of the hardware. Overruns occur when the internal First In, First Out (FIFO ...
WebThis function sets up the RX ring buffer to a specific UART handle. When the RX ring buffer is used, data received is stored into the ring buffer even when the user doesn't call the UART_TransferReceiveNonBlocking() API. If there is already data received in the ring buffer, the user can get the received data from the ring buffer directly. Note
