This leaves a stale device, which then causes a NULL pointer dereference in the code that handles deferred probing: [ 1.489982] Unable to handle kernel NULL pointer dereference at virtual address 00000074 [ 1.498110] pgd = (ptrval) [ 1.500838] [00000074] *pgd=00000000 [ 1.504432] Internal ...
We already enable MDIO, MDIO_DEVICE and IXGBE now. Is there anything else missing? Another question is how to check the NVM is configured to use MDIO functions, because the MDIO and LED functions share the same interface pins. Is it probably the reason why we can't get MDC/MDIO signal?
Perform an Avalon-MM master write to the MDIO core registers at address offset 0x21, specifying the external PHY device address (MDIO_DEVAD), port-address (MDIO_PRTAD) and register address (MDIO_REGAD). Issue an Avalon-MM master read of the 32-bit MDIO_ACCESS register at ...
