===== Partition scheme =====

<WRAP round important>Changing the partition scheme may affect the boot loader update capability and / or the kernel command line parameters!</WRAP>

The following partition scheme is used for SD / eMMC images

  * sector size 512 Byte
  * unpartitioned area: 4MiB (0x2000 sectors)

^ Sector           ^ Size                  ^ Usage                 ^
|0x0000 ... 0x0001 | 0x0002 sectors / 1kiB | MBR / Partition Table |
|0x0002 ... 0x07ff | 0x07fe sectors        | u-boot                |
|0x0800 ... 0x0fff | 0x0800 sectors / 1MiB | environment           | 
|0x1000 ... 0x17ff | 0x0800 sectors / 1MiB | device tree blob      |

  * 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 config/platform-tq-mba53/config/uboot-hd.config. The creation of the image is controlled using the project local PTXdist package image-uboot-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-MBa53/build-host/genimage. There is also a README file documenting how to use this tool.
