TSE with NicheStack Problem

I've got the NicheStack license.

I'm using NIOSII IDE 8.1

I've got the DP83848C ethernet chip.

I've got a custom CPU without the I2C.

My project based on the Simple Socket Server with a Static IP Address.

I have made sure that I assign a MAC address based on the Static IP Address and have written it into Flash. (keeping with the logic of the network_utilities.c for the NEEK)

The problem is that during "tse_mac_init" sometimes:

1. Messages look good and I can connect

2. sometimes all the messages look good and I CANNOT connect

3. sometimes I get WARNINGS and can connect

WARNING : PHY[0.0] - PHY not capable for Auto-Negotation

4. sometimes I get WARNINGS and CANNOT connect

WARNING : PHY[0.0] - PHY not capable for Auto-Negotation

3. And EVEN sometimes I get ERRORS and I CAN connect

ERROR : MAC Group[0] - No PHY connected!

ERROR : PHY[0.0] - No PHY connected! Speed = 100, Duplex = Full

There is no rhyme or reason to this as the code is the same.

Could it be an interaction with the uC-OS and the HAL ?

Any suggestions.

Thanks in advance

Janet

    For starters, it looks like you have a problem on the MDIO interface between the TSE core and you PHY chip. Could you connect Signaltap probes, or a scope on the pins and check if the signals are ok?

    It could also come from bad initialization of the PHY chip. Are you sending it a reset pulse on start up?
