标题: 【关闭】开机之后总是提示cdn-dp错误
本帖最后由 liqb365 于 2020-10-18 07:30 编辑

烧写的是：image-TB-RK3399ProD-Release-V1.3.rar里面的镜像
开机之后不断提示：
cdn-dp fec00000.dp: Direct firmware load for rockchip/dptx.bin failed with error -2

adb无法连接。

跟踪了一下log，是drivers/base/firmware_class.c报出的错误，具体含义不太理解。
请问这个是什么问题？怎么解决？

下面是开机log：

你好，你重现烧写下boot.img boot_linux.img uboot.img试下

这个问题是这样的，我烧写的时候，给flash.py脚本用的是-d选项。事实上，我只想烧写Android，所以改成-a之后没有出现这个问题。
虽然-d仍然存在这个问题，但是对于我而言，可以先不关注了。RK的工程师看到了可以去试试-d选项，进一步确认一下问题。
