Programming and Flash
Build applications as usual (see Building an Application for more details).
Configuring a Debug Probe
This board is configured by default to use the OpenSDA DAPLink Onboard Debug Probe, however the pyOCD Debug Host Tools do not yet support programming the external flashes on this board so you must flash the device by copying files
Configuring a Console
Regardless of your choice in debug probe, we will use the OpenSDA microcontroller as a USB-to-serial adapter for the serial console.
Connect a USB cable from your PC to Serial of SwiftIO.
Use the following settings with your serial terminal of choice (minicom, putty, etc.):
Speed: 115200
Data: 8 bits
Parity: None
Stop bits: 1
Flashing
Here is an example for the Hello World application.
Connect a USB cable from your PC to “Serial” port of SwiftIO.
On Ubuntu, DAPLink debug probes appear on the host
computer as a USB disk mounted to /media/<user>/SWIFTIODBGR/,
where <user> is your login name.
west build -b mm_swiftio samples/hello_world
cp build/zephyr/zephyr.bin /media/<user>/SWIFTIODBGR/
Open a serial terminal, reset the board (press the “reset” button), and you should see the following message in the terminal:
***** Booting Zephyr OS v2.1.0-rc1 *****
Hello World! mm_swiftio
