Boot problem

I flash my tx2i with the new L4T packages and I can’t boot there nothing on display port.
An on the serial I have only the following message
0000000 00 00 00 e3 3c ff bf ff 7f fb db fb bf ff f7 ff
0000020 ff ef ef ef ff df df ff bf bf 7f ff ff ff ff ff
Can anyone tell me how to read that please ?


Does your tx2i work fine with old L4T release? Just want to confirm the case.

Did you see any error log during flash?

It’s used to work with the version 28.2 but now when I reflash the old version it’s doesn’t work anymore.
I didn’t see any error when I flash the card .

Does this board still work if you fall back to rel-28.2?

No it’s doesn’t work anymore . I only changed the computer since the last time but I tried on Ubuntu 14 and 16 and I still have the same problem.
I noticed that on the flash log :

[  11.3889 ] tegrasign_v2 --key None --list blob_eks_sigheader.img_list.xml
[  11.3905 ] Assuming zero filled SBK key

Is that normal ?

Did you do anything to the board before it is dead?
Could you share the full flash log with us?
