1,修改文件sys_config.fex

[spi2_para]spi_used            = 1spi_cs_bitmap       = 1spi_cs0             = port:PC19<3><default><default><default>spi_cs1             = port:PB13<2><default><default><default>spi_sclk            = port:PC20<3><default><default><default>spi_mosi            = port:PC21<3><default><default><default>spi_miso            = port:PC22<3><default><default><default>[spi3_para]spi_used            = 0spi_cs_bitmap       = 1spi_cs0             = port:PA05<3><default><default><default>spi_cs1             = port:PA09<3><default><default><default>spi_sclk            = port:PA06<3><default><default><default>spi_mosi            = port:PA07<3><default><default><default>spi_miso            = port:PA08<3><default><default><default>[spi_devices]  spi_dev_num = 1  [spi_board0]  modalias = "spidev"  max_speed_hz = 12000000  bus_num = 2  chip_select = 0  mode = 3  irq_gpio = 3full_duplex = 0  manual_cs = 0
