nrf_serial_write stops when NRF_LOG_BACKEND_RTT_ENABLED

[xiSean]

serial-rtt.zipI'm having trouble debugging SDK14.1.0 example serial using NRF_LOG with NRF_LOG_BACKEND_RTT_ENABLED using the NRF52 DK, PCA10040.

With NRF_LOG_ENABLED set to 0 I see characters from nrf_serial_write on my terminal. With NRF_LOG_ENABLED set to 1 I do not, even though I can confirm nrf_serial_read is working because NRF_LOG_INFO prints the characters on my debug terminal.

How do I use NRF_LOG with RTT in an application that uses the serial port?

Edit: attached project zip file.

Could you send your project (edit question attach zip file) so we can have a look here ?

[xiSean]

Thanks for looking at this. I edited my question and attached my project as a zip file, but I don't see it attached. I've tried this with both Chrome and IE11 with the same results. Are attachments only visible on your side?

[Hung Bui]

No, it's not. Please make sure the example is as small as possible, remove any binary. You can upload it to other cloud storage and send us the link .

[xiSean]

Minimal project attached. After deleting all build outputs it's now working.

I'm seeing no problem.

Here is my screen:

Please try to test again with fresh copy of the SDK. I have slightly modified the project to make it work with abstract path to the SDK.
