How to detect Ethernet cable connection/disconnection?
|
||
|
|
------------------------------------------------------
|
||
|
|
|
||
|
|
NuttX supports Ethernet connection/disconnection events from Ethernet PHY
|
||
|
|
using signals (see ``nuttx/drivers/net/phy_notify.c``).
|
||
|
|
The network monitor thread at apps/netutils/netinit (see
|
||
|
|
``CONFIG_NETINIT_MONITOR``) will handle taking the network down if the cable
|
||
|
|
is unplugged and bringing it back up when the cable is restored.
|
||
|
|
It is important to note that your Ethernet controller driver of your
|
||
|
|
MCU needs to support CONFIG_ARCH_PHY_INTERRUPT (and implement
|
||
|
|
``arch_phy_irq()``).
