i.MX RT1064 Adjustable Timer Usage

[brian_donovan]

I am attempting to use the ENET Adjustable Timer on the MIMXRT1064 EVK demo board.

I have been configuring the ATCR register to capture a time and the attempt to read it via ATVR. According to the reference manual the CAPTURE and RESET commands should both reset to 0 when the command completes. I have found that neither of the commands reset. Once I issue a RESET or CAPTURE command the corresponding bit stays high. When I read ATVR I always receive a 0.

Is there a condition where commands issued to the ATCR will not complete?

Thank you

Hello Brian,

MCUXpresso SDK for IMXRT1064-EVK software package provides [txrx_ptp1588_transfer] demo, which shows the way to use ENET driver to receive and transmit frame in the 1588 feature required cases.

Please find related demo with below default path:

\SDK_2.7.0_EVK-MIMXRT1064\boards\evkmimxrt1064\driver_examples\enet\txrx_ptp1588_transfer

Wish it helps.

Have a great day,
Mike
