# Seeedstudio board

## Question

Asked by elettrozero on 2014-12-07 in Wireless.

Hi all, I purchased a seeedstudio Arduino shield with wizfi250 chip onboard.
Despite there’s a guide on the website for upgrading the firmware the chip doesn’t seem to enter into program mode by shorting the boot mode jumper.
Neither I made it by sending the at+fota command thru serial (the network didn’t show up).

Do you have any advises or suggestions, please?

Hello elettrozero

1. Connect WizFi250 to PC via USB-cable.

2. Short the boot-mode-jumper.

3. Launch the serial-terminal program.

4. Reset the WizFi250-EVB using reset button(or SW1 button).

5. Now, you can see the bootloader menu as below.

## [code]===================== WizFi Bootloader
