imx6q spi slave

[413734891]

         您好，我用一块linux开发板，处理器Imx6q的处理器，linux内核是4.1.15，使用到ECSPI2进行spid传输，现需要将ECSPI2设置为从站模式（slave mode），我应该操作哪些寄存器？以及在内核中如何查找到这些寄存器？有没有相似的例程或者链接？

Hi 留杰 付,

You can configure ECSPI2 in slave mode by configuring CHANNEL_MODE (specifically CHANNEL MODE[2] is for SPI channel 2 to 0 (slave mode)) in Control Register (ECSPIx_CONREG).

You can get above information from the imx6Q reference manual.
