Actually you don’t even need a booloader. Just set the rom start on your project to 0x0 and the processor will boot directly from your code. Your only way to do updates is via SWD unless you include the code for something like serial DFU.
If you want to do anything with BLE and the softdevice then you have to have your app in the flash space specified by the SD.
but when our device provide the customs, we don't use the swd to update the firmware, because the softdevice effect the code real time, so we don't plan to use the BLE, so only freertos application without ble.
