Hello Lars...
I'd run the application for the PS-2 Keyboard test (scan code ), available with the reference design of ml-401, in my EDK Project, and the things are working fine...
I'm able to see the scan-codes corresponding the key pressed on the hyperterminal..
Guess that indicates that the Hardware is fine...
But I couldn't check the signals on the scope...its only the 5v signal that is coming on the VCC line, pin no.4, even though i'd pressed the keys of the keyboard...
Also, had cross checked the hardware interrupt no..all ok...
Shall I send you the steps that have been used while building up the kernel-2.4
Kindly suggest
Thanx
Regards
Chhavi

Chhavi,
Did you connect the interrupt (ps2_2_intr) properly in your hardware design?
Does the hardware interrupt number match
CONFIG_XILINX_PS2_DUAL_REF_0_SYS_INTR2_IRQ? Can you see with a 'scope that
the keyboard signals on the PS/2 data and clock line when you press a key
(=hardware is OK)?
