1. Is there documentation for building the redundant bootloader (secondary boot) without fastboot for the imx8mm in an android environment?
2. Can the Secondary bootloader be used in a non-secure environment -- manually set the PErsist bit)?

My question is -- what is the best way to get the secondary image table onto the emmc per the documentation in the imx8mm security manual -- and this app note : i.MX 8MQ - ROM Redundant Boot for expansion device 
1. When I look at the fastboot code to flash u-boot the start offset on the emmc is 0x42

2. I am using an Android environment w/Secure boot

Question 1: How to program the secondary image table on the imx8mm eMMC per Chapter 6 of the Imx8mm Security manual?

Question 2: The secondary bootloader -- can it be a copy of the primary?
