A device uses one slave select, but in board file:

#if defined(CONFIG_SND_BF5XX_SOC_AD183X) \

        || defined(CONFIG_SND_BF5XX_SOC_AD183X_MODULE)

        {   

                .modalias = "ad183x",

                .max_speed_hz = 3125000,     /* max spi clock (SCK) speed in HZ

*/

                .bus_num = 0,

                .chip_select = 4,

                .platform_data = "ad1836", /* only includes chip name

for the moment */

                .controller_data = &ad1836_spi_chip_info,

                .mode = SPI_MODE_3,

        },  

#endif

 

#if defined(CONFIG_MMC_SPI) || defined(CONFIG_MMC_SPI_MODULE)

        {

                .modalias = "mmc_spi",

                .max_speed_hz = 20000000,     /* max spi clock (SCK) speed in

HZ */

                .bus_num = 0,

                .chip_select = 4,

                .platform_data = &bfin_mmc_spi_pdata,

                .controller_data = &mmc_spi_chip_info,

                .mode = SPI_MODE_3,

        },

#endif

 

In hardware connection, to run AD1836 and MMC at the same time, pls switch

AD1836 cs to PF5 or other, not sharing with MMC. And change the board file.

Build script failed to change chip_select value because board file has been

changed.

Fixed in test script.

Close it.
