我的疑问是：我使用spi1我觉得少一个 spi1m1_cs1_hs 这个参数把。我看了spi2 spi3 都有cs0 cs1，为什么我的cs1没有。是官方的dts有问题？请教怎么解决

dtsi的配置

&pinctrl {

rk3566 spi1做主机啊，

一般在spi设备驱动中去申请cs作为普通gpio用，spi通信时将gpio拉高

能说详细一点吗？到底要那种设置效果：比如平常cs低，当spi通信一次先拉高，通信完成后cs又拉低吗？或者cs一直拉高能正常工作吗

看应用场景。当你spi上挂多个设备时，需要多个gpio去拉从机的cs。驱动最好就是通信的时候拉高、通信完毕拉低

我现在把cs当gpio控制正常控制电压，但是我的sck用示波器测量读flash没信号。对了我使用pinctrl下面哪组是正常的。我是用spi1 m1组。

看设备吧，不用hs试一下。flash是什么型号，供电各方面是否正常，现在是怎么驱动

我试过不用hs 也是不行啊，flash型号BY25Q32ASSIG. flash电路是正常的，因为我们另外一个同样底板，fpga工程师是可以正常操作flash。
