[Linuxptp-users] PTP4L - i.MX6 implementation question

[Hugh R. <hu...@co...>]

Perhaps this is not the correct list to post this question but we are trying
to use PTP4L on an i.MX6.

 

The hardware timestamp counter seems to be stuck.

We can set it using phc_ctl, but it doesn't count.

 

On the i.MX6 configuration:

The GPR1 bits are being set in init imx6q_1588_init(void) from the
mach-imx6q.c file........we've added debug so we know that line of code is
being executed.

Our dtsi file includes the line MX6QDL_PAD_GPIO_16__ENET_REF_CLK
0x4001b0b1

 

What else do I need to do? Any help would be greatly appreciated.

 

Regards

 

Hugh
