Hi Eugene Hiihtaja

The latest elftosb User's Guide I can find is under SDK2.6.3 folder, it is Rev 4, 10/2018.

On this document, there is no specific description about SB2.1 layout.

I am checking it internally if there is new version available. I will let you know once I get feedback.

Have a nice day,

Jun Zhang

The difference of SB2.1 and SB2.0 will be documented in next version of AN12283, so far it's not published yet.

I can only provide you short description here:

"The 0A version of the LPC55S6xx silicon supports version 2.0 of the SB image format.
The 1B version of the LPC55S6xx silicon supports version 2.1 of the SB image format.
The main difference between version 2.0 and version 2.1 is in the usage of the digital signature.
SB 2.0 is encrypted and SB2.1 is encrypted + signed.
"

Have a great day,
Jun Zhang
