Hi all

I have tried to flash the nand due to problem with installing Armbian on nand and boot from sata.
I have CB2 2012-09-09 with nand. I was using PhoenixSuite 1.07 (which upgraded to 1.10), I was pressing FEL button when plugging miniUSB cable, PhoenixSuite on my windows 10 (later also windows xp) haven't detected CB, but now, after a few tries all I can see using FTDI cable is:

�HELLO! BOOT0 is starting!
boot0 version : 3.0.0
�HELLO! BOOT0 is starting!
boot0 version : 3.0.0

U-Boot SPL 2017.01-armbian (Feb 02 2017 - 02:16:44)
DRAM: 0 MiB
### ERROR ### Please RESET the board ###

U-Boot SPL 2017.01-armbian (Feb 02 2017 - 02:16:44)
DRAM: 0 MiB
### ERROR ### Please RESET the board ###

U-Boot SPL 2017.01-armbian (Feb 02 2017 - 02:16:44)
DRAM: 0 MiB
### ERROR ### Please RESET the board ###


Is this problem recoverable, why this has happend, cb2 was working fine booting from SD.

Replace the uBoot with another one, as that one doesn't work.

I have my CB2 in  FEL mode.
I have installed sunxi-tools and under my Linux:
sunxi-tools$ ./sunxi-fel --list --verbose
USB device 001:009   Allwinner A20     16516603:80518489:49534848:0882e61c

it finds CB2.

So using this tool and FEL mode can I write for instance:
cb-a20-lubuntu-server-13.06-v1.00.img
onto NAND and make CB2 work again booting from nand >

I have compiled uBoot and try to boot it from by sunxi-fel
command is:
./sunxi-fel uboot ../u-boot/u-boot-sunxi-with-spl.bin

But on console there is only:
U-Boot SPL 2017.05-rc2 (Apr 19 2017 - 13:57:46)
DRAM: 0 MiB
### ERROR ### Please RESET the board ###

So... is this problem recoverable ?
