Please note that the LSDK memory layout for TF-A boot flow explained in this topic is only applicable for LSDK 18.12 and newer releases.
The following table shows the memory layout of various firmware stored in NOR/NAND/QSPI flash device or SD card on all QorIQ Reference Design Boards.
When the board boots from NOR flash, the NOR bank from which the board boots is considered as the "current bank" and the other bank is considered as the "alternate bank". For example, if LS1043ARDB boots from NOR bank 4, to update an image on NOR bank 0, you need to use the "alternate bank" address range,0x64000000 - 0x64F00000.
| Firmware Definition | MaxSize | Flash Offset (QSPI/NAND flash) | Absolute address (NOR bank 0 on LS1043ARDB, LS1021ATWR) | Absolute address (NOR bank 4 LS1043ARDB, LS1021ATWR) | Absolute address (NOR bank 0 on LS2088ARDB) | Absolute address (NOR bank 4 on LS2088ARDB) | SD Start Block No. | |
