Will uarte interrupt call NRF_LOG_INFO, will run away the possibility of the processor? backend uses RTT
I set uarte receive dma buffer to 10, then the sender to use the 1M baud rate, continue to send data, I log in the uarte interrupt, I found several times before the RTT Viewer shows is correct, behind an error, and lead to my Processor running lost. When I turn off the LOG information, all the data received properly.
Taking into account in addition to SD or RTT, no other interrupt will preempt the uarte interrupt, so I think it is not RTT problem?
