CONFIG_ETH_MCUX_PTP_CLOCK_SRC_HZ

Frequency of the clock source for the PTP timer

Type: int

Help

Set the frequency in Hz sourced to the PTP timer.
If the value is set properly, the timer will be accurate.

Direct dependencies

PTP_CLOCK_MCUX && ETH_MCUX && NET_L2_ETHERNET

(Includes any dependencies from ifs and menus.)

Defaults
