因為不明原因 rootfs 只有 68M 所以要更換rootfs 可能會空間不夠
且發現 GPT PMBR size mismatch 錯誤 故先修正錯誤再更改空間

root@test-desktop:/home/share/test/rk-yocto-bsp# fdisk /dev/sdc

Changes will remain in memory only, until you decide to write them.            
Be careful before using the write command.                                     
                                                                               
GPT PMBR size mismatch (395263 != 61521919) will be corrected by w(rite).
