NRF5 SDK Makefile flags during the development

Question

Hi Team, 
 In SES, there are two builds debug and release. While in the armgcc Makefile there is just one type of build. 
 The one from the example looks like optimize for release -O3. I'm wondering what are the flags I should enable 
 to maximize (debugging info) during the development/debugging phase. 
 
 I have these switches flags turned on: 
 OPT = -O0 -g3 
 CFLAGS += -DDEBUG 
 Are there more flags I should turn on during the BLE development using softdevice? 
 Thanks.

While I'm trying to integrate the DFU buttonless service, I found an article from this forum suggested to turn these options on: 
 NRF_LOG_BACKEND_RTT_ENABLED 1 NRF_LOG_ENABLED 1 NRF_LOG_DEFAULT_LEVEL 4 NRF_SDH_BLE_LOG_ENABLED 1 NRF_SDH_BLE_LOG_LEVEL 4 NRF_SDH_LOG_ENABLED 1 NRF_SDH_LOG_LEVEL 4 
 
 They are super useful. I wonder if I'm missing some other switches that I should turn on. Thanks.

Hi, 
 The list of symbols you have found are very useful! I would also recommend you to define the symbol "DEBUG_NRF", which will enable ASSERT assessment in the libraries/drivers. 
 Note that the NRF_LOG_* and NRF_SDH_* symbols should ideally be set in the sdk_config.h file in your projet, not in the CFLAGS in the Makefile. 
 Best regards, Jørgen

Yes I do set those defines in sdk_config.h. Thanks for the last symbol DEBUG_NRF.
