SDK16, S112, 52810. I have DCDC set up and external 32.768 crystal oscillator on my board.
Here is my code part:
main()
nrf_power_dcdcen_set(true);
nrf_delay_ms(100);
// Initialize.
log_init();
timers_init();
power_management_init();
ble_stack_init();
adc_configure();
gap_params_init();
gatt_init();
advertising_init();
services_init();
conn_params_init();
peer_manager_init();
advertising_start(erase_bonds);
In the stack_init(), I have these codes at last:
err_code = sd_power_dcdc_mode_set(NRF_POWER_DCDC_ENABLE);
APP_ERROR_CHECK(err_code);
nrf_delay_ms(500);
It works fine with debugger right after programing. But once I power off/on, it doesn't reboot, even with debugger.
If I comment out the sd_power_dcdc_mode_set code from stack_init, It can reboot with debugger. But, it can NOT reboot once I take the debugger off.
In the sdk_config.h, I use the default set up for the softdevice clock configuration, as I thought I do have external crystal oscillator:
#define NRF_SDH_CLOCK_LF_SRC 1
#define NRF_SDH_CLOCK_LF_RC_CTIV 0
#define NRF_SDH_CLOCK_LF_RC_TEMP_CTIV 0
#define NRF_SDH_CLOCK_LF_ACCURACY 7
I don't know what to do now. Please help me out here, thanks
