更换lcd屏幕
我手上有一块480*854的屏幕，现在想测试一下 在.fex文件中我发现，只要我把下面的这两个参数改成480*854，在后面打包、烧录运行时就会出现问题fb0_width = 480
fb0_height = 854
问题如下：
/etc/init.d/rcS: line 60:1231 Segmentation fault insmod /system/vendor/modules/mali.ko
挂载mali.ko文件显示段错误，具体打印消息如下：
我这种情况是gpu不能用吗？我应该怎么解决这个问题{:2_29:}

您修改成其他的分辨率，您在编译的时候还会出现这个报错吗？还是说只有您改成这个特定分辨率的时候有问题？您有尝试过重新编译一份源码然后修改分辨率等参数后再次观看现象吗？ shuishui 发表于 2023-8-21 10:55
