https://devzone.nordicsemi.com/f/nordic-q-a/45729/uart-problem-always-reboot-systemHi! I have a problem with UART. SDK15. S132 6.0, nRF52832 I added UART to my project and watching strange behavior: when I attempt to send anything to UART project reboots. I see that problem in a nrfx_uart.c file in the string 318: whileen-USTelligent Community 13Thu, 04 Apr 2019 13:56:40 GMThttps://devzone.nordicsemi.com/thread/180343?ContentTypeID=1Thu, 04 Apr 2019 13:56:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c7900900-e3f9-4277-a9c0-57456d860518Mikhail<p>Very strange. But yestarday it doesn&#39;t worked. Today I take another MCU and works fine. Possible reason in broken nRF52.</p> <p>Thanks.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/180260?ContentTypeID=1Thu, 04 Apr 2019 10:28:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bc581842-5d2d-4f1b-a44f-15ce55eadac4Edvin<p>Hello,</p> <p>Do you have logging enabled in your project? Can you try to add &quot;DEBUG&quot; to your preprocessor defines? The application doesn&#39;t restart by itself, so my bet is that you are hitting the error handler, which causes a reboot. Adding DEBUG to your preprocessor defines tells the nRF to log the cause of the issue before it reboots.</p> <p></p> <p>is NRF_LOG_ENABLED defined to 1 in sdk_config?</p> <p></p> <p>Best regards,</p> <p>Edvin</p><div style="clear:both;"></div>
