Hi,
I have a yocto image: image.img.
On my build PC I have
> file image.img
image.img: DOS/MBR boot sector; partition 1 : ID=0xee, start-CHS (0x0,0,1),
end-CHS (0x3ff,254,63), startsector 1, 802815 sectors, extended partition
table (last)
> fdisk -l image.img
Disk image.img: 392 MiB, 411041792 bytes, 802816 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: gpt
Disk identifier: 45C0DFD4-267E-4C4A-820F-B94F180165E7
Device Start End Sectors Size Type
image.img1 2048 800767 798720 390M Linux filesystem
And I can calculate the offset (512 * 2048 = 1048576) to mount image.img1
to let say /tmp/update
mount -t ext4 -o loop,offset=1048576 image.img /tmp/update
Now on the target device (Tegra), I'd like to write the content of
image.img1 to /dev/mmcblk0p38. But the output of busybox's fdisk is
different
> fdisk -l image.img
Disk image.img: 392 MB, 411041792 bytes, 802816 sectors
49 cylinders, 255 heads, 63 sectors/track
Units: sectors of 1 * 512 = 512 bytes
Device Boot StartCHS EndCHS StartLBA EndLBA Sectors
Size Id Type
image.img1 0,0,1 1023,254,63 1 802815 802815
391M ee EFI GPT
Partition 1 has different physical/logical start (non-Linux?):
phys=(0,0,1) logical=(0,0,2)
Partition 1 has different physical/logical end:
phys=(1023,254,63) logical=(49,248,7)
How can I deduce the offset from this output?
Better even, is there a way to dd image.img1 directly to /dev/mmcblk0p38?
Thanks,
