Firstly,I downloaded the image file from the official website.

Verify MD5

As you see,it's a correct version.

Then,I Write the image file to the SD card.

write imag

At last,I copy three files to the root directory.

I'm sure these three file are matched with my device.And I I compared my production amount of SD card and successful SD card file size is the same.But the system always faid to start.If I use the official SD card,it's OK.

I want to know which step is wrong with my SD card production?I have compared the step of official web many times.

Thank you very much!
