LX2160a: Alternate image support with single NOR flash

csr202 — Tue, 26 Apr 2022 22:02:23 GMT

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?

Comments from the software team:
1) Please share the dump of DCFG CCSR memory.
2) The customer should flashed two different firmware images at offset 0MB and 8MB.
-> Block copy command in PBI should be different for 0 MB and 8MB offset.
-> FYI: TFA does not support alternate boot feature.
