Help, How to flash the NAND?

Hi everybody,
Sorry, I'm from Tunisia and I don't speak Chineese, so I'm writing in english and hope that you will answer me in english.

I bought the embedsky TQ210 board. it's really a promising board and I'm enjoying implementing some features.
After finishing my devs, I want to Flash the NAND with my android image and a custom logo but I did'nt understand how to do that using the  TQBoard DNW tool.

Is there someone on the forum that succeed to do this? if yes, How to proceed?
can you please provide me the steps to follow to accomplish this?

my board driver is correctly installed.
This is how I did to try flash the nand:

• I switched off the board,
• I changed all the DIP switches to the right to enable the usb mode (according to the doc, I only need to put the OM5 to on (to the right))
• I switched on the board
• in the TQ210 doInload tool, I tried to connect to my board, I pressed space, but nothing happened, I'm not getting the menu!!!
  

Thank you so much for your help

Cheers,
Slim

you should import the U-boot image when using TQBoard DNW tool
if you do that and nothing happened.you can try press the KeyOn button 3-5sec to set up the PMU.

Hi,
I still getting problems to flash the board.
This is what I get when I load the uboot:

is there another way to flash the board without using DNW Tool? and is there a way to change the logo without DNW tool?

Thank you so much
