TLK110 EVM interfacing with ESP32 Wroom kit

Postby bitto.c » Mon Oct 16, 2017 10:30 am

We are trying to evaluate ESP32 with TLK110 Phy interface, We followed the connections as per the Comments and Documents in Ethernet sample code.

Our connection:
// TXD0 = GPIO19
// TXD1 = GPIO22
// TX_EN = GPIO21
// RXD0 = GPIO25
// RXD1 = GPIO26
// CLK == GPIO0

We are seeing Phy getting init and is able to read all registers from Phy succesfully.
But always Phy gives Link status as Down.

Is there a schematic or reference design with TLK110 so we can verify.

Attaching some debug logs we are getting on Registers
