NRF_LOG and UART not working simultaneously

[phob]

Hi,

I am using experimental_ble_app_blinky example. In that NRF_LOG over UART was implemented. I Added some UART code for my use. But after flashing code was not working at all. Printf and NRF_LOG_INFO was not working simultaneously. Then i commented printf then it was working fine. But i was not able to receive any data in controller. Following setting i did..

UART_DEFAULT_CONFIG_HWFC: Disabled
NRF_LOG_DEFERRED: Disabled
NRF_LOG_BACKEND_SERIAL_UART_FLOW_CONTROL: Disabled

controller was crashing continously. Here is my main.c and sdk_config.h files... github.com/.../

What SDK version?

I am using SDK v12.2. Softdevice is S132 and NRF52 Board. Also Board is restarting continously. i disabled NRF_LOGs and Changed it to printf. I changed to LOG over RTT instead of UART. I have updated my files on github. github.com/.../

It is getting stuck at ble_stack_init() function., If i comment init_uart function then code doesn't get reset but if i use uart initialization then it get reset continuously. Even if i use printf then also application is not working properly. i think there might be nrf_log task is running. Which might using UART service. What could be other possibilities?

Hi Phob!

Please take a look at this thread. It's not using the same example but you should be able to find the information you need.

Let me know if it doesn't help and you still are experiencing problems.

Best regards,
Joakim.

Thanks Joakim. i don't required NRF_LOG, so i have removed all the NRF_LOG_xxxx calls from files. But now i am facing problem like printf is not at all working and processor gets stuck there only. But i could use uart_put_char to send single character. i have attached sdk_config.h file.
