Hi everyone,
we are using a i210IS on our board, with an external copper PHY, connected through SGMII and MDIO.
The NVM has been successfully programmed with Dev_Start_I210_Sgmii_NOMNG_8Mb_A2_3.25_0.03.
The host is WinCE7, using the latest Intel Driver.
During the driver start-up, we realised that the external MDIO bus was used in I2C mode, so the relevant changes were made to both the Driver code and NVM bit settings.
Now, the i210 communicates to the PHY on the external MDIO bus, in MDIO mode.
However, everytime the i210 starts a cycle on the MDIO bus, it stops the clock (MDC) in the middle of the transaction.
The preamble is shifted out, then the command, but then the clock is stoppped. After a while, the READY bit is activated, along with the ERROR bit.
We suspect a Power Management issue, did some tests with different settings, but we always get the same behavior.
Any clue?
