按键对应的GPIO 是 PB5

请问需要怎么用程序检测按键状态变化呢？

使用芯片是 F133-A
使用的flash是spi nand
在用户空间向secure storage分区写入数据后，重启设备后，写入的数据被擦除。
全志提供的在uboot 中读写的demo，和在用户空间读写的demo 两者操作的地址不一致，在uboot 中读写的demo 仍具有数据保护特性

用户空间读写demo

D1-H_Tina_Linux_存储_开发指南.pdf

请问怎么能够让两者操作同一段地址

烧录镜像后重启无法进入系统

有没有前辈能指点一下是什么情况导致的
而且想要再次进行烧录的时候检测不到USB设备了
