Hi everyone,
I implemented nrf51 flashing through SWD (external MCU is used). After first flashing and reset when we enter debug mode on SWD second time we have a busy state (NVMC_READY (0x4001E000 + 0x400) is set to zero) from NVMC. What could be the reason?
PS: if we power down NRF51 we can flash it once again, but only once.
