void opt_reset_func(void) { NRF_POWER->RESET = 1; } this is opt_reset_func function implementations

Which SoftDevice and SDK version are you using? You should not write to the POWER registers after initializing the SoftDevice, you should use sd_nvic_SystemReset() instead.

my SoftDevice is s110_nrf51_8.0.0_softdevice,i want enable reset pin without power down,so i did like this

Using sd_nvic_SystemReset() instead of NRF_POWER->RESET = 1; solved the problem?

this code when i use NRFgo studio to respectively download softdevice、 bootloader、 application，lead to HardFault,but use nrfjprog is normal，
