We have a requirement where, there is a single NOR flash physically available, we need 2 set of images (main and alternate) to be independently deployed to a single NOR flash on a different offsets. Each image set includes a set of RCW/PBI and associated trusted firmware.
As per “QorIQ Trust Architecture 3.0 User Guide”:
For LX2160A, if a valid RCW is not found at NVRAM interface + offset, the ISBC will check for a valid secondary RCW at NVRAM interface + offset + 8 MB.
I tried the above scenario but BL1 (boot rom fw) doesn't read alternate RCW at NVRAM interface + offset + 8 MB. Is there any other configuration required to support this scenario ?
Can you provide more details/document which explains step by step instructions to test this scenario?
