2.4 Flashing NINA-B30 open CPU software
The NINA-B30 open CPU module can be flashed over the SWD interface.
2.4.1 Flashing over the SWD interface
For SWD flashing, an external debugger must be connected to the SWD interface of the
NINA-B30 module. A third-party tool such as the J-flash or the nRF Connect Programmer from Nordic
Semiconductor is used to flash the SW via the external debugger.
☞ The external debugger SEGGER J-Link BASE works with the NINA-B30 modules.
☞ The EVK-NINA-B30 evaluation kit incorporates an onboard debugger and can therefore be flashed
without any external debugger. See also the EVK-NINA-B3 user guide [3].
Flashing the software
⚠ As flashing the software erases the Bluetooth device address, it must be manually rewritten to
the module after flashing. Ensure that you make a note of your Bluetooth device address before
continuing with the flashing procedure. See also Bluetooth MAC address and other production
data.
In the nRF Connect Programmer, drag-and-drop the hex files you want to program in the GUI, as
shown in Figure 9.
