About Timestamp

I am currently working on Wired sync TDoA-Positioning.
I’m trying the external clock and the sync. The external clock seems working ok.
Tag transmit a blink message, periodically.
And Anchor receive the blink message very well.
But, I have a problem
After reading data register(dwt_readrxdata),
checking rx time stamp register(dwt_readrxtimestamp)
The value is always ‘0’.
please advice check point to me.

Thank you
Best regards,

Regarding the zero’s
Would you have loaded the LDE during initialisation? Ie did you use dwt_initialise(DWT_LOADNONE) instead of dwt_initialise(DWT_LOADUCODE).
