Hello,
I have question about some aspects of Secure Boot especially on LS1046ARDB. I did not find sufficient explanation on LSDK or TA user guide. My questions are the following:
- Is the barker code the same thing as the hard coded preamble that LSDK User Guide Rev. 19.09_311219 discussed about on the page 217?
- What is the aims of scatter gather table and what can be the discontiguous image it supports?
- In case of scatter gather table, does each segment in the signed hash represent a discontiguous image?
- In the LSDK User Guide Rev. 19.09_311219, it was said TA 2.X supports Key List. LS1046ARDB supports TA 2.1. IS TA 2.X the same as TA 2.1?
- If LS1046ARDB supports Key List for Secure Boot, how to specify list of keys in Code Signing Tools inputs files. I did not find any field related to that for LS1046ARDB inside input_uboot_secure file. Is there another way to do it?
- In the document Enable Trust Architecture and Secure Boot on LS10xx, Rev. A, 05/2016, on page 12 it was said ... remember to program the write protect (WP) otherwise a hacker may be able to modify the SRKH, OTPMK ...?
How the OTPMK can be modifed when the fuse programming is irreversible?
7. Code Signing Tool 19.09 supports u-boot, does it support Secure Boot using UEFI? How to use it to sign uefi?
