MX8MN: To create dek blob on target it requires to call dek_blob command twice

Hi all,

we have implemented encryption support for the MX8MN processor. But to create the dek blob on the target as mentioned in the documentation in uboot. For the first dek blob creation everything works fine. But we had to execute the dek_blob command twice to create a dek blob for the second dek. 

Is their any timeout required between execution of the dek_blob command?

Best regards,

Hello,

   generally no need for the timeout. Note, different keys will be generated 
for blob creation for each dec_blob command.

 

Regards,
Yuri.
