IMXRT117x HAB Authentication from secondary bootloader

Hi All,

I have a question on IMXRT117x's HAB Authentication from secondary bootloader. In my case the BootRom jumps to the secondary bootloader(SBL) first and then it has to jump to the Application. In my case the SBL will be copied from QSPI external NOR flash (address of SBL : 0x30000000)  to the ITC RAM and will execute there. The application on the other hand, is an Execute In Place(XIP) binary(address of Application: 0x30100000).

Everything works fine when I am running unsigned SBL. It jumps from BootROM to unsigned SBL and then to the unsigned App.

Now I am testing HAB authentication and signed the SBL. But when this executes it does not really jump into the Application (I am not able to see those logs from the App). 

I have not separately signed the application. Is that required? I tried to sign the Application using both MCUXpresso secure provisioning tool and  AN13250SW. Both did not work and the reason I guess is that the application starting address is 0x30100000

Please let me know whether I am doing something wrong.

Regards,

Jimmy
