Seger RTT logging backend not working under newer versions of Segger Embedded Studio (4.16+)

[Atok]

Dear community


We encounter a problem where the Segger RTT backend for the NRF logging library does not work in Segger Embedded Studio versions newer than 4.12 (4.16+).

While working flawlessly in 4.12, NRF_LOG_PROCESS() and NRF_LOG_FLUSH() are running in an infinite call loop in newer versions: We receive a non-ending stream of whitespace characters on the RTT Debug console.

If the UART logging backend is enabled as well, we sometimes encounter a valid message on the RTT Debug Console popping up shortly. On the UART backend we encounter a non-ending stream of random characters.

We currently use Segger Embedded Studio 4.12 to circumvent the problem.

Do you encounter similar issues?

Hi,

Could you try to set NRF_FPRINTF_FLAG_AUTOMATIC_CR_ON_LF_ENABLED in sdk_config.h to 0 ? See this post for more information.

Thank you very much: This indeed solves the problems in newer SES versions.
