56Mod自制电路板，进入shutdown关机模式电流为260uA，请问如何检查漏电原因呢？
int main(void)
{
/\* Output a message on console using printf function \*/
//rt_kprintf("Hello world!\\n");
rt_kprintf("Shutdown, press key1 to wake up system...\\n");
/\* delay 10ms to wait print complete \*/
rt_thread_mdelay(10);
HAL_PMU_SelectWakeupPin(0, 0); //PB54 for 58x, PB32 for 56x
HAL_PMU_EnablePinWakeup(0, 0);
//hwp_rtc->PBR0R = 0x10a0;
hwp_rtc->PAWKUP = 0x003F003F;
//hwp_rtc->PBWKUP = 0x003F003F;
hwp_pmuc->WKUP_CNT = 0x000F000F;
rt_hw_interrupt_disable();
/\* Enter shutdown mode, system can be woken up by KEY1 \*/
HAL_PMU_EnterShutdown();
/\* while loop until system is down \*/
while (1) {};
// /\* Infinite loop \*/
// while (1)
// {
// // Delay for 1000 ms to yield CPU time to other threads
// rt_thread_mdelay(1000);
// }
return 0;
}
