Programming and Debugging
The siwx917_dk2605a board supports the runners and associated west commands listed below.
| flash | debug | rtt | attach | debugserver | |
|---|---|---|---|---|---|
| jlink | ✅ | ✅ (default) | ✅ | ✅ | ✅ |
| silabs_commander | ✅ (default) |
Building and Flashing
Applications for the siwx917_dk2605a board can be built in the usual
way. The flash method requires on Simplicity Commander installed on the host.
Then, connect the board to your host computer using the USB port.
Here’s an example of building and flashing the Hello World sample:
# From the root of the zephyr repository
west build -b siwx917_dk2605a samples/hello_world
west flash
Open a serial terminal (minicom, putty, etc.) with the following settings:
Speed: 115200
Data: 8 bits
Parity: None
Stop bits: 1
Reset the board and you should see the following message in the terminal:
Hello World! siwx917_dk2605a
Debugging
Debugging relies on JLink tool. JLink is not able to flash the firmware. So
debug session has to be done in two steps. west flash will flash the
firmware using Simplicity Commander. Then west attach will use JLink to
attach to the board. The Zephyr image may has already booted when user runs
west attach. User may execute monitor reset in the gdb prompt to reset
the board.
