SD卡的命令格式:命令CMD0就是0,CMD16就是16,以此类推。 SD卡的命令总共有12类,下表为几个比较重要的命令: 4、SD卡初始化(SPI) SPI操作模式下:在SD卡收到复位命令时,CS为有效电平(低电平),则SPI模式被启用,在发送CMD之前要先发送74个时钟,64个为内部供电上升时间,10个用于SD卡同步;之后才能开始CMD操作,...

(and I see nothing hinting at that in your schematic), you need to supply external flash.- Either way, you cannot use the pins the flash is connected to for anything else. That includes SPICLK and SPICS1.Also, given that you don't have an antenna, you won't get WiFi/BT/... ....
