@linguini1 Here is a log for when it failed:
sdc/hci systick count=429490(+5) ticks=429490(+5) ctrl=00000007
reload=0009c3ff current=0004ef5b intctrl=00000000
sdc/low systick count=429500(+10) ticks=3(+-429487) ctrl=00000007
reload=0009c3ff current=00067373 intctrl=00000000
Within nrf52_sdc.c I was calling this debug function:
/****************************************************************************
* Name: nrf52_sdc_debug_systick
****************************************************************************/
static void nrf52_sdc_debug_systick(FAR const char *tag)
{
#ifdef CONFIG_ARMV7M_SYSTICK
static uint32_t last_systick_count;
static clock_t last_sched_ticks;
static uint32_t log_count;
uint32_t systick_count = systick_debug_count();
clock_t sched_ticks = clock_systime_ticks();
uint32_t systick_ctrl = getreg32(NVIC_SYSTICK_CTRL);
uint32_t systick_reload = getreg32(NVIC_SYSTICK_RELOAD);
uint32_t systick_current = getreg32(NVIC_SYSTICK_CURRENT);
uint32_t intctrl = getreg32(NVIC_INTCTRL);
log_count++;
printf("sdc/%s systick count=%lu(+%ld) ticks=%lu(+%ld) "
"ctrl=%08lx reload=%08lx current=%08lx intctrl=%08lx\n",
tag,
(unsigned long)systick_count,
(long)(systick_count - last_systick_count),
(unsigned long)sched_ticks,
(long)(sched_ticks - last_sched_ticks),
(unsigned long)systick_ctrl,
(unsigned long)systick_reload,
(unsigned long)systick_current,
(unsigned long)intctrl);
last_systick_count = systick_count;
last_sched_ticks = sched_ticks;
UNUSED(log_count);
#else
UNUSED(tag);
#endif
}
I hope this helps.
