When running FreeRTOS with powersave disabled, what clock source provides the tick through platform_tick_isr? Is it the external 32.768 KHz crystal, LPO, or is it derived from the oscillator that is internal to the 1GC module?
Out of thousands of devices shipped we are seeing one that has about 17% error and another that has about 10% error in a periodic scheduled event triggered through a FreeRTOS timer.
The clock source that provides the tick through platform_tick_isr is internal to the 1GC module with powersave disabled. The oscillator is internal to the 1GC module with the default frequency of 37.4 MHz.
