cgpt

[shaunak]

Hi All,

I m trying to do and update of my chromium. After downloading the
package when it tries to run the cgpt tool it gives error. My platform
is ARM where the main rootfs is /dev/mmcblk0p9 and backup partition
is /dev/mmcblk0p11.

When i ran cgpt show separately i got this:

start size part contents
0 1 PMBR
1 1 INVALID Pri GPT header
2 32 INVALID Pri GPT table
30775263 32 INVALID Sec GPT table
1 1 INVALID Sec GPT header

WARNING: one of the GPT header/entries is invalid, please run 'cgpt
repair'


"cgpt repair" also didn't helped.

Also,"gdisk" of drive /dev/mmcblk0 gives this :

GPT fdisk (gdisk) version 0.6.4

Partition table scan:
MBR: protective
BSD: not present
APM: not present
