我想使用一个配置为SPI Master的MSP430来引导DA14586。(使用数据表中指定的P2_0/SPI_CLK, P2_3/SPI_EN, P2_4/SPI_DO, P2_9/SPI_DI引脚)。当MSP430发送SPI主引导协议(根据UM-B-079软件平台参考表40)，我没有得到响应(我期待ACK或NACK字节3 &6).相反，DA14586切换到SPI Master并搜索外部flash模块(根据UM-B-079中的引导顺序)。

我如何确保DA14586知道我试图从外部SPI Master引导它?我是否需要在一个时间框架内开始沟通?看起来DA14586在大约13毫秒后试图与外部闪光通信(我用示波器检查)。我一直试图在13毫秒之前从MSP430发送主引导协议，但它似乎忽略了我试图引导它。< / p > < / div > < / div > < / div > < div class =”字段field-name-field-forum-keywords field-type-taxonomy-term-reference field-label-above”> < div class = "字段标签" >关键词:,< / div > < div class = "字段条目" > < div class =”field-item甚至“> < a href = " / resource-keywords / da14586-spi-boot”“=“skos:概念”属性=“rdfs: label skos: prefLabel” datatype="">DA14586 SPI Boot
