My FCMini is a zombie!

First,My FCMini is not truly brick.

I had forgot that the stock boot0 is no message without pressing 's' keys!

So with 's' keys , boot0 show messsage as boot1 has wrong checksum.

 

This is my perfect NESC stock boot0 messages

And , this is my zombie FCMini stock message

It is clearly what causes my brick will not wake up.

 

madmonkey gives me u-boot update tools,I can continue to trying update.
