Using the latest LF5.15.5_1.0.0 on the IMX8MPEVK trying to use half-duplex e.g. 10baseT/Half or 100baseT/Half crashes the ENET_QOS imx-dwmac driver. Any other link modes including 10baseT/Full and 100baseT/Full seem to work fine. What could be the issue here?
As follows what I did:
root@imx8mpevk:~# ethtool -s eth1 advertise 0x01
And the crash which then happens:
