ENET 1588 channel 2 event capture mode not functional

Postby Hugh3226 » Tue Feb 21, 2017 1:33 pm

Just found this errata:
ERR005895 ENET: ENET 1588 channel 2 event capture mode not functional

Which might explain why I can't get it to work. Grrrrrrr.

The default for this signal is GPIO19....................

Is there any way I can hook onto GPIO19 on the DART?

Regards
Hugh

Hi,
GPIO19 is connected internally on SOM and not exported to connectors.
you can use ENET_1588_EVENT1_IN, ENET_1588_EVENT1_OUT exported on pins 48,50
see datasheet page 24.

Aviad,

Thanks but...

ENET_1588_EVENT1_OUT is currently set in the dtsi file to produce ENET_MDIO (MX6QDL_PAD_ENET_MDIO__ENET_MDIO)
Is that not critical to the ethernet function?

While I have your attention I'll start a new thread about getting the PTP hardware timestamping working.

Regards
Hugh

Hi,
It is required for Ethernet operation, but you can export ENET_MDIO, ENET_MDC function also from J1.9, J1.15 if
you wish to test event capture.

Aviad,

Yes I might be able to butcher the VAR-DT6CustomBoard.....

If you let me have the design files it would be much easier to do some planning.

I can't run without ethernet so I'll have to butcher the MDIO_DATA track off RN101........very difficult (impossible) to do without the gerbers.

Regards
Hugh
