Re: [lwip-users] Cable unplugged
Top posting is a crime!
Here's how I do it in Atmel-ese... no OS, in the main while(1) loop:
<>
modCount++;
...
if (!(modCount%0x0008))// check Ethernet PHY once in a
while to make sure we're connected
{
if (ethernetOK != ERR_OK)// only worried about initial try
for connection here.
{
// test for Ethernet OK
ethernetOK = init_ethernet();// put skips in place for
second time through
}
else // this handles unplug notification... replug should
be automatic after first successful init_ethernet()
{
static bool alarmLamps = false;
gmac_enable_management(GMAC, true); // this is
necessary for direct access
gmac_phy_read(GMAC, BOARD_GMAC_PHY_ADDR, GMII_BMSR,
_stat1);// get status from PHY
gmac_enable_management(GMAC, false); // give PHY back
to GMAC
if ((ul_stat1 & GMII_LINK_STATUS) == 0)// We are
unplugged, or something
{// do something! blink lamps etc

had to try and auto negotiate first.

[lwip-users] Cable unplugged
This is not directly LWIP related but I was wondering if there was a way to detect when cable is unplugged through a GMII/RMII interface? Specifically my hardware does not have the carrier sense pin connected to microcontroller and I was wondering if there was a way to poll the GMII/RMII registers to see when a cable is connected or not? I did not see anything in the documentation right off but thought I would ask, as maybe I am not looking at the correct registers.
