楼主你好！

我发现你SW8配置不对，您试试这个：

通过查看所有烧录后的image，复位设备，改变板子启动模式为boot from internal模式，BT_CFG[0]=1,即（SW8 1-ON, 2-OFF, 3-ON, 4-OFF） 然后断电，重新上电。发现LED闪烁，所以可以说明BEE加密已经工作。

看看是否能启动？

如果不行，你就用我case里面的软件。

Best Regards,

Hi @claire_chen ,

   In the previous time, I do the RT1020 BEE on my side.

   You can refer to my post:

https://www.nxpic.org.cn/module/forum/thread-619420-1-1.html

   As you are from China, you also can read the Chinese doc.

After you read it, if you still have issues, just kindly let me know.

Best Regards,

Kerry

Hi kerry，

    Thank you for your reply. We have already referred to this post before, but it still has the same phenomenon. The writing was successful, but the encryption was not successful, and the code cannot run.

Hi @claire_chen ,

    If that method also can't works, Your chip may mistakely operated.

   Do you have any new chip to test it on your side or not?

   You can create an private case, then I can share my testing file to you, as it can't put in the public side.

Best Regards,

Kerry
