Hi, my 1-button system off/on example works perfectly fine on nRF52 DK. However, when I move the exact same code to nRF52805, there are some errors.
I choose pin 21 as the system off/on pin. By default, pin 21 is a reset pin. So firstly, according to this link (see the verified answer), I removed the default reset pin function. Then, I build & run the application code to nRF52805.
By using RTT viewer, I found that the code doesn't execute bsp_init(BSP_INIT_BUTTONS, bsp_evt_handler). It's NOT an issue on nRF52 DK. But nRF52805 has this issue.
I attached my entire project code here in a ZIP file. Thanks in advance!
