I'm working on secure boot of ls1021a-iot, I can follow the steps in A0001-Secure-boot.pdf file in LS1021A-Rev2_iot-20150907 using the demo images provided by freescale.
But I'm not sure about something as below, can you help me?
There is a step to burn key hash256 to the fuse on uboot which boot from sd card as below.
=>mw 1e80020 0x02000000
=>md 1e80020 1
I not sure about the fuse address for ls1021a-iot, I think 01e80234 is the start address for OTPMKR and 01e80254 is the start address for SRKHRn, Is that right? What's the address 1e80020 used for? Is it for the ITS fuse? If it's not, what's the address for ITS fuse? Is there any document about these address?
I have burned the hash of demo public key to the fuse, if I want to burn another hash of a new key what's the address? Is there any document about this?
Thanks in advance.
