#!$%@?..de nie wiem co jest. Partycjonuję kartę SD pod embedded linux na ubuntu używając fdiska. Jedna partycja boot fat16 i jedna ext4 na rootfs.

sudo fdisk -l /dev/mmcblk0

Disk /dev/mmcblk0: 14,9 GiB, 15931539456 bytes, 31116288 sectors

Units: sectors of 1 * 512 = 512 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disklabel type: dos

Disk identifier: 0x69c763cc

Device Boot Start End Sectors Size Id Type

/dev/mmcblk0p1 * 2048 4196351 4194304 2G 6 FAT16

/dev/mmcblk0p2 4196352 31116287 26919936 12,9G 83 Linux

I po spartycjonowaniu nie montuje się druga partycja, a wypisuje mi to co na screenie.

Dmesg zwraca:

Pomuszcie miraski.

[SharkyShark]

jak mam problem z kartą sd to zazwyczaj najpierw używam "dd if=/dev/zero of=..." a później tworzę partycję od nowa.

[Kryspin013]

@WilczurZnahor: czemu fat16 a nie 32?

[WilczurZnahor]

@yuim: @SharkyShark: faktycznie poszlo...
@Kryspin013: w sumie to nie wiem, z rozpędu tak wybrałem w fdisk bo nie widziałem innego
