You need to read PHY_BSR register (1) and check bit 3 ... this is the link
status. This is what I am doing in a task.
The reason for doing the above is that a PHY with RMII has no link interrupt
and the simplest way is to read the
basic status register.
Yes, I know, but I wonder where, in the code, to poll that register. Do
I need to provide a task as you do? And netif_set_link_up() has to be
called only from this task?
Do you have a fully functional driver and initialize code that works for you ?
I have an implementation... Is the sample code provided by NXP in
KSDK2.2 (our board is very similar to FRDM K64). They do some strange
things, but they have provided a task that only deals with receiving the
data from network. PHY polling is done in an high level (application)
task that deal with UDP packets.
