Other Parts Discussed in Thread: HALCOGEN
Hello,
I was trying to develop driver code and test app for TMS570LC4357 Ethernet driver and Marvell 88Q1010 PHY. I have tested the code in HDK board its working fine.
All tweaking need for Marvell 88Q1010 is done.
The pins mappings to Marvell 88Q1010 are the following.
MII_TX_CLK : U7
MII_TXEN : E4
MII_TXD[0] : U8
MII_TXD[1] : R1
MII_TXD[2] : T2
MII_TXD[3] : G4
MII_RXCLK : T4
MII_RX_DV : U6
MII_RXD[0] : U4
MII_RXD[1] : T3
MII_RXD[2] : U3
MII_RXD[0] : V3
The halcogen configuration with respect to the above pins is done, generated the code.
The PHY is outputting 25Mhz on its MII_TX_CLK pin.
It seems like the TMSxx is not detecting the TX_CLK signal, TX is not happening.
RX is working fine.
what all can be the reasons for this issue?
NB: unable to probe the MII_TX_CLK pin of TMSxx to check whether clk is being routed correctly, due to Complex board design.
Kindly give valuable suggestions.
warm regards
Anandhu Ramesh
