    Can it be done ?

    I adjust the scripts page an i get now a good nios2_system.h tha looks similar to the uart's 

    /* Executing ...scripts/nios2_system.h/altera_avalon_spi.pm */
/* Redefining spi_0 -> spi0 */# undef  na_spi_0# undef  na_spi_0_irq
# define na_spi0                                 ((np_spi *) 0x82120980)# define na_spi0_irq                                                   13
/* Redefining spi_1 -> spi1 */# undef  na_spi_1# undef  na_spi_1_irq
# define na_spi1                                 ((np_spi *) 0x821209a0)# define na_spi1_irq                                                   14

    But is i f i want to build the kernel now i get the follow error's 

    make: Leaving directory `/cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x'

make: ***  Error 1

    I think i must adjust the driver spi.c in the dir /drivers/char/spi.c

    Can someone help me ??
