Hi, i am trying to configure the external phy from CPU via MDIO slave but i am able to read even address in phy registers but not able to read odd address registers from phy.

Hi Dheeraj,

Is your base address and offset address set correctly on software?

Also please refer to sessions 9.4 & 9.2.4. from below link

Hi Anand,

Base address and offset address is correct, because i am able to access(read) PHY Registers.

this sessions 9.4 & 9.2.4. is related to Ethernet MDIO but in my design i am using MDIO Slave. This is the different IP and he is acting as a slave to CPU.

on processor side we have only MDIO MDC lines. so we cannot use Ethernet MDIO .

Thanks,

Hi Dheera,

Can you share the user guide?

Sure Anand,

please find the below attached document.

Hi,

Presently I don't have access to the IP I will try to get.

Meanwhile, try to use a signal tap for debugging & share images.
