hello_world¶

Minimal nsx application for the Apollo510 EVB. Initialises the runtime core and prints a message to SWO in a loop.

This is the recommended starting point for new users — it validates that your toolchain, board connection, and SWO viewer are all working.

Build & Run¶

nsx configure --app-dir .
nsx build     --app-dir .
nsx flash     --app-dir .      # requires JLink + Apollo510 EVB
nsx view      --app-dir .      # opens SWO viewer

Expected Output¶

The SWO viewer will print:

Hello from nsx! (0)
Hello from nsx! (1)
Hello from nsx! (2)
...

Messages repeat once per second. If you see nothing, check:

1. Board is powered and connected via SWD (JLink)
2. nsx flash completed without errors
3. SWO pin is not remapped — the default EVB configuration works out of the box
