Using nRF52DK with VisualGDB. Trying to get logging enabled

[borje]

(NRF_LOG_ENABLED=1) but get lots of undefined references from e.g uart-related parts (nrf_drv_uart_init). Any tricks to get by easily? Börje

Then you also need to enable the RTT logging. Make sure you have NRF_LOG_BACKEND_SERIAL_USES_RTT 1 in sdk_config.h. Remember to enable the NRF_LOG in sdk_config.h. See this answer, and this answer on how to use the configuration wizard.

I actually got it to work on the COM9 using PuTTY. However, the app still crashes at power_manage with the following TTY output: SDH:INFO:sd_ble_enable: RAM START at 0x20002128 SDH:WARNING:sd_ble_enable: app_ram_base should be adjusted to 0x20001fe8 SDH:WARNING:ram size should be adjusted to 0xe018 APP:INFO:Heart rate collector example APP_ERROR:ERROR:Fatal

Great! Now you need to adjust the RAM settings. In Keil go to "Options for Target.." to change the RAM start and size. Under "Read/Write Memory Areas" set "Start" to 0x20001fe8 and "Size" to 0xe018.
