Partition scheme

Changing the partition scheme may affect the boot loader update capability and / or the kernel command line parameters!

SD / eMMC images

Sector Size Usage
0x0000 … 0x0000 0x0001 sector / 512 Byte MBR / Partition Table
0x0008 … 0x07ff 0x07f8 sectors / 1020 KiB u-boot
0x0800 … 0x0fff 0x0800 sectors / 1 MiB environment
0x1000 … 0x17ff 0x0800 sectors / 1 MiB device tree blob
Partition Size Usage
1 8 MiB Kernel image
2 256 MiB root FS
3 256 MiB Spare, not formatted

The partition scheme is defined using the config file config/platform-tq-mbls102xa/config/images/uboot-hd.config.

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-MBLS102x/build-host/genimage. There is also a README file documenting how to use this tool.

SPI NOR

Sector Size Usage
0x0 … 0x0 0x1 sectors / 64 KiB RCW
0x1 … 0x8 0x8 sectors / 524 KiB U-Boot QSPI

Environment organisation:
* configured environment size: 32kiB (64 Sectors)
* environment type: redundand
* primary environment (sectors): 0x0800 … 0x0840 (0x100000 … 0x107fff)
* redundand environment (sectors): 0x0810 … 0x081f (0x108000 … 0x10ffff)
