Hi, after successfully boot, I start to write some app on my uClinux 2.6.x on LPC2468. My application must communicate with some device on ttyS1 which is second serial port on LPC. But when I open port with on console with echo "Hello" >/dev/ttyS1, I get flood on console with message:
serial8250: too much work for irq7 serial8250: too much work for irq7 serial8250: too much work for irq7
I try various configuration, with enabled and disabled Serial IRQ sharing, with and without extended 8250 driver options and pretty much everything that I think is related to serial ports. Also I try to enable LPC serial support but then compile is not finished.
How I can resolve this? Regards, Diego
