could please post the output of "sfdisk -d /dev/mmcblk0" ?
# partition table of /dev/mmcblk0 unit: sectors /dev/mmcblk0p1 : start= 64, size= 39854080, Id= c /dev/mmcblk0p2 : start= 56631360, size= 4194304, Id=83 /dev/mmcblk0p3 : start= 60825664, size= 1572864, Id=82 /dev/mmcblk0p4 : start= 39854144, size= 16777216, Id= 5 /dev/mmcblk0p5 : start= 39854160, size= 9765680, Id=76 /dev/mmcblk0p6 : start= 49619856, size= 7011504, Id=76
the firmware only hardcodes /dev/mmcblk0p1. you can safely change the other partition numbers.
