Hello,
Hi Ran,
I would like to ask a question regarding the MII functionality : When using mii commands (cmd_mii.c) everything works well, until trying to do a ping (using net command). After any ping try(with success or not), the mii read function is stuck. Maybe it has to do with davinci mii implementation, but I am not sure if this is the problem or not. Any advice is welcomed.
I think this is not a general issue, as with other processors/boards everything works fine. However, after using a net command, the dev->halt callback is called, and this could disable the phy.
If you are using the davinci_emac driver, take a look at the davinci_eth_close() function. It can be that when the controller is turned off, you cannot access to the phy anymore.
