1) See CPU reference Manual. This sector can be used for Redundant Boot Support
2) Environment organisation:

  * configured environment size: 8kiB (16 Sectors)
  * environment type: redundand
  * primary environment (sectors): 0x0800 ... 0x080f (0x100000 ... 0x101fff)
  * redundand environment (sectors): 0x0810 ... 0x081f (0x102000 ... 0x103fff)


  * partitioned area:

^ Partition ^ Size     ^ Usage                ^
|  1        | 4 MiB    | Kernel image         |
|  2        | 256 MiB  | root FS              |
|  3        | 256 MiB  | Spare, not formatted |
|  4        | ----     | ----                 |

The partition scheme is defined using the config file configs/platform-tq-mbls102xa/config/images//uboot-sd.config. The creation of the image is controlled using the PTXdist packages image-uboot-tqma6<q|s>-hd.

To create the image the genimage host tool is used. This tool is automatically selected and built. You can find the build directory under <BSPROOT>/platform-MBa6x/build-host/genimage. There is also a README file documenting how to use this tool.
