Hello ,
I' am trying to mount a sdcard using fatfs and the card connected using spi.
I don't fine the right way to define cyg_spi_mmc_dev0 inside my application.

With the following should i write  : " cyg_spi_mmc_dev0 = 
mmc_spi_device.spi_device; "

cyg_spi_lpc2xxx_dev_t mmc_spi_device CYG_SPI_DEVICE_ON_BUS(0) = {
       .spi_device.spi_bus = &cyg_spi_lpc2xxx_bus0.spi_bus,        //
       .spi_cpha = 0,                 // Clock phase
       .spi_cpol = 0,                 // Clock polarity
       .spi_lsbf = 0,                 // LSB first
       .spi_baud = 1000000,           // 1 Mbit/s
       .spi_cs = mmc_cs               // Chip select driver
};
