I am currently using RMII Interface. clock 50Mhz externally and not using internal clock.
Below is pin mux setting for rmii signals.
#ifdef CONFIG_DRIVER_TI_EMAC
static const struct pinmux_config emac_pins[] = {
#ifdef CONFIG_DRIVER_TI_EMAC_USE_RMII
{ pinmux(15), 0, 0 },
{ pinmux(15), 8, 1 },
{ pinmux(14), 8, 2 },
{ pinmux(14), 8, 2 },
{ pinmux(14), 8, 3 },
{ pinmux(14), 8, 4 },
{ pinmux(14), 8, 5 },
{ pinmux(14), 8, 6 },
{ pinmux(14), 8, 7 },
#else
{ pinmux(2), 8, 1 },
{ pinmux(2), 8, 2 },
{ pinmux(2), 8, 3 },
{ pinmux(2), 8, 4 },
{ pinmux(2), 8, 5 },
{ pinmux(2), 8, 6 },
{ pinmux(2), 8, 7 },
{ pinmux(3), 8, 0 },
{ pinmux(3), 8, 1 },
{ pinmux(3), 8, 2 },
{ pinmux(3), 8, 3 },
{ pinmux(3), 8, 4 },
{ pinmux(3), 8, 5 },
{ pinmux(3), 8, 6 },
{ pinmux(3), 8, 7 },
#endif /* CONFIG_DRIVER_TI_EMAC_USE_RMII */
{ pinmux(4), 8, 0 },
{ pinmux(4), 8, 1 }
};
#endif /* CONFIG_DRIVER_TI_EMAC */
Please help to solve the problem.
