Changing the partition scheme may affect the boot loader update capability and / or the kernel command line parameters!
Sector numbers are in hexadecimal (as expected by U-Boot's mmc
command), size is given in hex (=number of sectors) and dezimal (= size in byte).
Sector first | Sector last | Size | Usage |
---|---|---|---|
0x000000 | 0x000000 | 0x0001 sector / 512 Byte | MBR / Partition Table |
0x000001 | 0x000001 | 0x0001 sector / 512 Byte | free |
0x000002 | 0x0007FF | 0x07FE sectors / 1023 KiB | u-boot |
0x000800 | 0x000FFF | 0x0800 sectors / 1 MiB | u-boot environment |
0x001000 | 0x001FFF | 0x1000 sectors / 2 MiB | free |
0x002000 | 0x00BFFF | 0xA000 sectors / 20 MiB | boot / firmware (Kernel, devicetrees) |
0x00C000 | 0x08BFFF | 0x80000 sectors / 256 MiB | root |
0x08C000 | 0x10BFFF | 0x80000 sectors / 256 MiB | spare, unformatted |
