Hi all! I have 2.6.12 up and running on my mpc5200, but are experiencing a problem with the serial line. PSC1+3 are both registered as uarts during boot
Serial: MPC52xx PSC driver ttyS0 at MMIO 0xf0002000 (irq = 39) is a MPC52xx PSC ttyS2 at MMIO 0xf0002400 (irq = 41) is a MPC52xx PSC , but I don't get the 2nd line to work. # cat /proc/tty/driver/mpc52xx_psc_uart shows serinfo:1.0 driver revision: 0: uart:MPC52xx PSC mmio:0xF0002000 irq:39 tx:3546 rx:112 RTS|CTS|DTR|DSR|CD 2: uart:MPC52xx PSC mmio:0xF0002400 irq:41 tx:0 rx:0 CTS|DSR|CD # (IRQ 41 isn't shown under /proc/interrupts - and no entry under /proc/irq/41, but the irq 41 count IS increased when writing to the port - as shown under /proc/stat) under 2.4.31 both serial lines work, so it's not hardware. In 2.4 the serial lines show up as /dev/tts/{0,1}, whereas in 2.6 they show up as /dev/tts/{0,2}. Does anyone know what the problem might be? thanks in advance.. /carl
