[En-Nut-Discussion] SW SPI bus reading data

[Aigars]

On re configuring NutOS&rebuilding and adding to httpserv.c file:
NUTSPINODE my_node = {
     &spiBus0Gpio, /* Pointer to the bus controller driver. */
     NULL, /* Optional pointer to device specific settings. */
     10000, /* SPI clock rate. */
     3, /* SPI mode. */
     8, /* SPI data bits. */
     0,  /* Chip select index. */
};
I get:
c:\ethernut-4.6.5\nutapp_charon2\httpd>make
avr-gcc -c -mmcu=atmega128 -Os -fno-delete-null-pointer-checks -Wall 
-Wstrict-prototypes -Wa,-ahlms=httpserv.lst -DCHARON2 -D__HARVARD_ARCH__ 
-I../../nutbld_charon2/include -I../../nut/include  httpserv.c -o httpserv.o
httpserv.c:259: error: expected '=', ',', ';', 'asm' or '__attribute__' 
before 'my_node'
httpserv.c: In function 'NutAppMain':
httpserv.c:886: warning: no return statement in function returning non-void
make: *** [httpserv.o] Error 1

The same if I add your definition.

NUTSPINODE nodeIli9341_0 = {
     NULL,                       /*!< \brief Pointer to the bus controller driver, node_bus. */
     NULL,                       /*!< \brief Pointer to the bus device driver specific settings, node_stat. */
     ILI9341_0_SPI_RATE,         /*!< \brief Initial clock rate, node_rate. */
     ILI9341_SPI_MODE,           /*!< \brief Initial mode, node_mode. */
     8,                          /*!< \brief Initial data bits, node_bits. */
     FB0_CS_INDEX,               /*!< \brief Chip select, node_cs. */
     &ili9341_0_dcb,             /*!< \brief Pointer to our private device control block, node_dcb. */
};


Is there something else I missed?
Without defining SPI device build is OK.
