XR32 CSI验证发现有点问题，求大佬给个OV7670、GC0308 的demo我抄抄

[YuzukiTsuru]

照着camera_demo里的改了，砍了wifi部分，然后把gc0308的驱动部分换成了OV7670，结果出现[os E] OS_SemaphoreWait():110, handle 0

修改后的SDK放到Github上了https://github.com/YuzukiHD/XR32SDK，项目是project/example/camera

报错

换了GC0308，也有问题，无法拍摄图像，但是初始化什么的都没问题。。

@yuzukitsuru 电压崩了吧

[YuzukiTsuru]

@gregrgr gc0308的10脚的1.8v我拆了也是一样的

[gregrgr]

@yuzukitsuru 我也Layout一个试试
