root@zx3-pm3-zynq7:/var/volatile/tmp# ubiupdatevol /dev/ubi0_0 
/tmp/zx3-image.ubifs
[  272.730913] mmc0: Card removed during transfer!
[  272.735368] mmc0: Resetting controller.

This messages are been printed many times, but no error for
ubi updatevol is returned or something.

I 've been thinking the same thing :)

I don't know if this is going to help but when I first tried to load
root filesystem from NAND, kernel printed that the rootfs variable was
not set right and that the available options are:
mtdblock0
mtdblock1
mtdblock2

I get this when I run

root@zx3-pm3-zynq7:/var/volatile/tmp# cat /proc/partitions
major minor  #blocks  name

   31        0       5120 mtdblock0
   31        1       1024 mtdblock1
   31        2     518144 mtdblock2

Also,

root@zx3-pm3-zynq7:/var/volatile/tmp# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00500000 00020000 "nand-linux"
mtd1: 00100000 00020000 "nand-device-tree"
mtd2: 1fa00000 00020000 "nand-rootfs"

I don't know what's going on :)
