uClinux: Use the alternative touch screen driver

Hi,

I'm having a hard time to communicate with the external touch controller.

I specified the app "inputattach" with proper parameters.

Driver for the touch controller (Elo) was recognized (Inputattach running in background).

But testing event0 (assigned to "elo touch" driver) has no result.

I also tried the console device via serial port (Terminal emulator: HyperTerminal) which worked out fine.

As earlier mentioned "setserial" brings still the following report:

/> setserial -a /dev/ttyS0

/dev/ttyS0, Line 0, UART: undefined, Port: 0x0000, IRQ: 6

Baud_base: 3125000, close_delay: 50, divisor: 0

closing_wait: 3000

Flags: spd_normal

Main Configuration of the kernel:

+ Device Driver -> Char. devices -> Virtual terminal

+ Device Driver -> Input device supp. -> Event interface

+ Device Driver -> Input device supp. -> Event debugging

+ Device Driver -> Input device supp. -> Touchscreens -> Elo serial touch

+ Device Driver -> Input device supp. -> Hardware I/O ports Serial port line discipline enabled

+ Device Driver -> Char. devices -> Serial drivers -> Altera UART support enabled (default baudrate 9600), Altera JTAG UART support (+ console support))

(mouse and keyboard not included yet)

Am I missing some options?

PS: I also tried to activate the serial drivers "8250/16550 and compatible serial support" (Device drivers -> Char. devices -> serial drivers)

but an error appears during compilation stating:

../nios2-linux/linux-2.6/drivers/serial/8250c:104:24: asm/serial.h: no such file or directory

..(compilation aborted)

I would appreciate if someone could help me on that problem.

Thank you in advance!
