Arduino Primo Core

[shubhangir]

Hi Dev Zone, I am attempting to flash a blink led app, based on Zephyr (nrf52_pca10040), to the primo core (contains Nrf52832), through Jlink debugger on a Linux machine. In my app, I write to GPIO pin number 10 (since this is connected to the blue LED on the Primo Core board.) I have verified this works with the Arduino code base (available as open-source lib for Primo Core), where I flash 3 hex file components to the board: Soft device, bootloader, and app. On the Zephyr, these are the equivalent steps followed: docs.zephyrproject.org/.../nordic_segger.html

I have also run the Jlink debugger with breakpoints set within the zephyr app main() code, and I see that the code appears to execute.

My question is, I believe the zephyr hex file includes bootloader+app. So in theory, it should be enough to simply flash this to the board? Is there a way to verify that the boot+app is flashed correctly to the board?

Thanks and regards, Shubhangi

I'm not sure if this answers your questions, but if you have the hex file you can use nrfjprog with the --verify command to compare the flash against the hex file.
