In SDK 15 the bootloader DFU enter check in nrf_bootloader.c has the following code:
if (NRF_BL_DFU_ENTER_METHOD_GPREGRET &&
(nrf_power_gpregret_get() & BOOTLOADER_DFU_START))
{
NRF_LOG_DEBUG("DFU mode requested via GPREGRET.");
return true;
}
Why isn't this (NRF_BL_DFU_ENTER_METHOD_GPREGRET && (nrf_power_gpregret_get() & BOOTLOADER_DFU_START) == BOOTLOADER_DFU_START) ?
