Re: SV: [microblaze-uclinux] Problem in using the PS/2 Keyboard
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)?
