    How can a 2nd ethernet port be enabled? The MT7688A has a 5-port ethernet switch, so it would be nice to easily enable at least 1 more ethernet port by adding magnetics. Is this possible?<br/><br/>

    Hi,   Could you tell me where you see "mt7688a has 5-port ethernet switch"? I only found that it has 1-port fast ethernet phy.

    The datasheet mentions a 5 port switch, because the 1 port PHY is actually port 6 on the switch.  it can have 5 ethernet ports.The pinout for the linkit smart 7688 has 4 pins going to the ethernet port 0 on breakout board labelled MDI_P0 and there is another set of 4 pins labelled MDI_P1.The uboot appears to set the MDI_P1 pins as part of SPIS, but i want to use as 2nd ethernet port.

    The datasheet is for MT7688, and not for Linkit7688. The subtle difference here is the way this board is manufactured several IO ports had to be made unavailable. If you can prepare your own board using MT7688, you will have full access to all of these peripherals and a PCIe port too..

    it is "mylinkit.local" If you are still now able to ssh into it.. use network mapping tools to look for the ip address "who is on my wifi for windows" or nmap for a linux console. I have tried the static IP thing, beleive me.. in the long run, you wud not wan that, just stick with a host name.

    use a I2C or SPI based sensor module and read data from there.

    The project with webcam streaming - are streamed data writen do flash memory? Because flash memory has shorter life when many wrintig/deleting to it. So I am affraid if MT7866 will die quickly?<br/><br/>
