Failed to get PTP Hardware Clock support on LA1224ARDB

[nxf47487]

Hi

I'd like to verify the PTP feature on LA1224ARDB. Tried the prebuild and rebuilt Linux kernels with PTP related options on. However, failed to get PTP Hardware Clock support on eth0/eth1 and there is no /dev/ptp and /dev/pps generated. Could you give me some hints? Thanks.

Here are related info:

Board: LA1224-RDB, Board version: A

BSP: 0.6

Hello Tony Hsu,

Please check whether the following options are enable in your Kernel configuration file.

CONFIG_FSL_DPAA2_ETH

CONFIG_FSL_DPAA2_PTP_CLOCK

Thanks,

Yiping

Thanks. I got it solved by updating the DPL file to enable PTP.
