Hey,
Yesterday we decided to update SDK to 17.0.2. After this change our FreeRTOS stopped working.
We started investigating where is the problem and we found that when vPortSetupTimerInterrupt calls nrf_drv_clock_lfclk_request then nrfx_clock_lfclk_start is not called because m_clock_cb.lfclk_on is already true.
Reson why this bool is true is change in this new SDK, in function nrf_drv_clock_init this code has been added:
if (nrf_wdt_started()){m_clock_cb.lfclk_on = true;}
First look at this may look fine but after restart under Embedded Studio NRF_WDT->RUNSTATUS has value 1 even BEFORE watchdog initialization.
In nrfx_wdt code I didn't found any reference to nrfx_clock_lfclk, so is this `if` valid?
If it should be like this, solution can be something like this:
if (nrf_wdt_started() && nrf_clock_lf_is_running())
{
m_clock_cb.lfclk_on = true;
}
What is a valid solution for this issue?
BR,
zori
