ok, let´s try to create partitions.

download this tool: here

stick into your pc, start create mini

choose your stick, format


boot dgs and mount and install images to sda2, sda3 or sda4.

if you want to install later a new one, format the part with:
Code:
mkfs.ext2 -I 128 -b 4096 -L MINI2 /dev/sda2
maybe you have to change your bootargs:
Code:
fw_setenv menu_1 'setenv bootusb "run bootargsusb;usb reset;ext2load usb 0:2 a5ff0000 boot/uImage;bootm a5ff0000";setenv bootargsusb "setenv bootargs console=ttyAS1,115200 root=/dev/sda2 rw init=/bin/devinit ip=$ipaddr:$serverip:$gateway:$netmask:cuberevo:eth0:off mem=128m coprocessor_mem=4m@0x10000000,4m@0x10400000 rootdelay=6 nwhwconf=device:eth0,hwaddr:$ethaddr";setenv bootcmd "run bootusb";saveenv;front_puts SDA2-USB;boot'fw_setenv menu_2 'setenv bootusb "run bootargsusb;usb reset;ext2load usb 0:3 a5ff0000 boot/uImage;bootm a5ff0000";setenv bootargsusb "setenv bootargs console=ttyAS1,115200 root=/dev/sda3 rw init=/bin/devinit ip=$ipaddr:$serverip:$gateway:$netmask:cuberevo:eth0:off mem=128m coprocessor_mem=4m@0x10000000,4m@0x10400000 rootdelay=6 nwhwconf=device:eth0,hwaddr:$ethaddr";setenv bootcmd "run bootusb";saveenv;front_puts SDA3-USB;boot'

then you have press 1 to get image from sda2
2-->sda3
3-->sda4

later if you test with sata drive, you have to press:
4-->sda2
5-->sda3
6-->sda4
