How to check whether internet connectivity or not for EK-TM4C1294XL Development Board

Other Parts Discussed in Thread: EK-TM4C1294XL

Hi,

We are using EK-TM4C1294XL Development Board for development.

We have connected board to router and got IP address and sending data to a server.

After board is started Internet link between Router and Sever was there. After 5-10 mins we have brought down this link and board is still assigned IP address.

We want to know this down link event to perform other operations.

I have checked enet_weather example and in eth_client.c file,it goes to tcp_connect() every time and returns ERR_OK even internet is down from router to server.

I also tried to look into Exosite example but not able to find useful steps.

Can you please provide any guidance to check this?

Thanks,

Can you let me know what version of TIRTOS, NDK, and CCS you are using?

If you look in the EMACSnow driver in TIRTOS, it looks at a register to see if the link is up.

Basically the line looks like this:

EMACSnow_private.linkUp = (EMACPHYRead(EMAC0_BASE, 0, EPHY_BMSR) & EPHY_BMSR_LINKSTAT);
