nrf52dk systick calibration value

[shreeharsha]

Hi, I have configured systick for 1msec value with Ticks=64000. When I read the systick calibration register value, the value is 0xc0000000. This indicates the Tenms register value is zero.

The description says SoC vendor has to provide this value. Can any one help on this.

Thanks in advance.

Hi John DeWitt,

Thanks for your reply. I still have couple of questions.

1. So is it not possible to use systick as counter on nordic nrf52dk.
2. Can I disable sd_app_evt_wait() and use systick.
3. I tired configuring RTC as counter but missing about 30-40 ticks for 5 sec. How to get accurate count value using RTC. Am running on RIOT OS.

Looking forward for your valuable reply.
