RE: Ethernet PHY Device API


My understanding is the init() routine does not initialize the PHY but
the MII interface for accessing the PHY. There is no API defined in eCos
for actually setting up the PHY, please correct me if I am wrong.

Are you calling _eth_phy_init(eth_phy_access_t *f) ? This should execute
your init() code prior to probe your PHY.

Hello all,

Where should I put the code initializing PHY? The optional init()
function I 
defined along with the required stat() doesn't seem to ever get called.


Thanks,
/Mikhail
