[SDK 15.2 ble_app_hrs_freertos] Logger problem

[drk_tg]

Hi,


I'm using ble_app_hrs_freertos from SDK 15.2 on PCA10056. I noticed that logs stop working (RTT) when I increase configTOTAL_HEAP_SIZE to 64k.

I tried play with various settings in sdk config but without any success. Does anybody faced with this problem? I will be grateful for help.


Best regards,

Hi,

I'm not able to reproduce this issue.

Taking the ble_app_hrs_freertos example in SDK 15.2, setting configTOTAL_HEAP_SIZE to 64000, and setting NRF_LOG_BACKEND_RTT_ENABLED to 1, and NRF_LOG_BACKEND_UART_ENABLED to 0, everything seems to work fine. Both "HRS FreeRTOS example started" and "Fast advertising." is printed when the program starts.

Which compiler and JLink version are you using?

I have JLink 6.40 and compiled example with gcc-arm-none-eabi-6-2017-q2

I attached my compile result: /cfs-file/__key/communityserver-discussions-components-files/4/5344.nrf52840_5F00_xxaa.hex

I tested your hex file together with S140 v6.1.0, and RTT-viewer V6.40, and it worked fine here.

I used incorrect target device (NRF52 instead of NRF52840_XXAA) in JLink RTT Viewer. After change everything works well.

Thank you for help!
