Value overflow in watchdog initialization code.

Hi,

Yes, this is fixed in SDK 16.0.0 (which uses a newer version of nrfx where this is fixed).

The fix was to replace this from SDK 15.3:

nrf_wdt_reload_value_set((p_config->reload_value * 32768) / 1000);

With this in SDK 16.0:

uint64_t ticks = (p_config->reload_value * 32768ULL) / 1000;
NRFX_ASSERT(ticks <= UINT32_MAX);

nrf_wdt_reload_value_set((uint32_t) ticks);

Has a new SDK been released that addresses this overflow? We need something in the 2,000,000 (mSec) range.

thanks

Hi,

Thank you for reporting the issue. It has already been discussed here and should be fixed in a future SDK release.
