In the release package for the RT1020, in the folder:




there are various .bd files.


Some of these are for creating a bootable image that is either unsigned, signed or encrypted.


In the signed and encrypted versions there is a section called:


section (SEC_CSF_HEADER;


In it is the variable Header_Version, which is set to 4.2 (signed files) or 4.3 (encrypted files):








1. Why are they different?

2. Where do we get this version from?

3. Or what should we be setting to?

4. Is there a document that describes the difference between 4.2 and 4.3 etc?


Many thanks.
