应该是死一回重启，大部分会在这里
看log像是dsi初始化的时候，request irq挂掉了，这一块代码都是默认的，你应该没改动过吧?如果是随机性错误，报错地方不一样，那问题就大了。

DSI_STATUS DSI_RegUpdate(void)里

不会改SD卡 改出来的问题吧 powerid怎么是4 SD卡的不75为11和12值
我也碰到这个问题,有没有解决的啊?
FLASH是什么型号?
是不是EMMC5.0的
EMMC5.0 是要打补丁的
eMCP是三星的KMK7X000VM_B314, 8G+1G的
我这里也是EMMC版本5的问题,已经解决！
怎么解决的咯, 可以分享出来不?
就VER值改大啊. 可以看以前的贴自.
msdc0: card voltage not support
是電壓的問題吧
EMMC5.0问题
打了emmc5.0的补丁，也没有作用，请问一下小编，还有什么原因吗?
