[MCU Boot] Logs & Swap issue

[evan_nxlc]

Hi, 

I evaluate MCUBOOT and trying to understand how it works. I am using a nRF52840DK. I have base my demo on this course (Exercise 1 - DFU over UART - Nordic Developer Academy (nordicsemi.com))
I would like to do DFU through UART and seeing log, it's why I choose to put logs of MCUBOOT on RTT to don't have conflicts. Is it the right approach ?

Because it seems to still have conflicts cause my RTT logs stop in the middle of a swap sectors


What can cause that ? 

Thanks in advance

Hello,

Using RTT for logging while performing a Device Firmware Update (DFU) via UART is an effective approach to avoid conflicts. This may be due to the log buffe. Can you try increasing the log buffer(CONFIG_SEGGER_RTT_BUFFER_SIZE_UP)?

From the logs, I can see that you are on version 2.7rc2. I recommend updating to the stable version 2.7.0.

Kind regards,

Abhijith

Hello,

Increasing the buffer size to 2048 allows more messages to be displayed.
Thanks for your proposition. It works!

Best regards
