Debugging Ethernet 10G MAC CSR

[ZaidSahawneh]

I am trying to debug my Ethernet 10G MAC using the CSR interface, however, when I attempt a read (at address = offset + 20 for example; Tx Packet Control), I see the read signal go high via Signal Tap but no further activity occurs. My understanding is that these registers should have default reset values. Does anyone know why my reads lock up? Thank you.

Hi,

Debugging Steps

1. Verify Address and Offset

Ensure that the address you are reading from is correctly calculated and falls within the valid range of the CSR space. An incorrect address could lead to undefined behavior.

2. Check Reset and Initialization

Confirm that the MAC and the CSR interface are properly reset and initialized. Default values should be loaded into the registers upon reset. Verify this with the appropriate reset signals and sequences.

Best regards,
