Hi Tomeu, Dinh, Andreas
I need a sum and help from you to go ahead on the
tx timeout.
The "stmmac: MDIO fixes" seems to be the candidate to
fix the phy connection and I will send the V2 asap (Andreas' comment).
So, supposing the probe is ok and phy is connected,
I need your input ...
Tomeu: after revering the 0e80bdc9a72d (stmmac: first frame
prep at the end of xmit routine) the network is
not stable and there is a timeout after a while.
The box has 3.50 with normal desc settings.
Dinh: the network is ok, I wonder if you can share a boot
log just to understand if the normal or enhanced
descriptors are used.
Here it is:
...
[ 0.850523] stmmac - user ID: 0x10, Synopsys ID: 0x37
[ 0.855570] Ring mode enabled
[ 0.858611] DMA HW capability register supported
[ 0.863128] Enhanced/Alternate descriptors
[ 0.867482] Enabled extended descriptors
[ 0.871482] RX Checksum Offload Engine supported (type 2)
[ 0.876948] TX Checksum insertion supported
[ 0.881204] Enable RX Mitigation via HW Watchdog Timer
[ 0.886863] socfpga-dwmac ff702000.ethernet eth0: No MDIO subnode found
[ 0.899090] libphy: stmmac: probed
[ 0.902484] eth0: PHY ID 00221611 at 4 IRQ POLL (stmmac-0:04) active
Thx Dinh, so you are using the Enhanced/Alternate descriptors
I am debugging on my side on a setup with normal descriptors, I let you
know
