7688 升级固件中掉电了，应如何处理

以下是官方给的处理办法：

Hi,

 

When you connect the 7688 device with the PC/laptop, it is getting detected under USB ports ?

 

Try to re-flash the firmware using a USB storage by following the below steps. ( Section 4.6.1 Using a USB drive of Developers guide  )

 

Using a USB drive : The USB drive must be in FAT file system or the file cannot be recognized by the LinkIt Smart 7688 development platform.

 

1) Save the firmware file (lks7688.img) in the root directory of a USB drive. You can download the latest firmware from MediaTek Labs website.

 

2) Plug the USB drive to LinkIt Smart 7688.

 

3) Press the Wi-Fi and MPU (Reset) button, then release the MPU Reset button only but hold the Wi-Fi button for at least 5 seconds and release (Wi-Fi LED turns off),.

    Do not press the Wi-Fi button for longer than 20s or it will upgrade the bootloader.

 

4) LinkIt Smart 7688 will start to read the firmware image (Wi-Fi LED blinks fast) and perform the firmware upgrade process (Wi-Fi LED blinks slowly).

    This process takes about 3 minutes to finish.

 

 

Regards,

Ajith

如果你的bootload没坏的话，可以usb刷
