Hi, please open your *emProject in a text editor to try and see if you can spot other configuration differences between "Release" and "Debug". The Release configuration should obviously have consumed less memory.

I have the same problem here. The release version take significantly more Flash and and Ram memory and won't run. The Debug version run fine.

I have plenty of Flash space left but Ram goes from 8.6 k to 2.6k left of 64 kb (nrf52832) when I set Release mode. I suspect that there might be a conflict with Ram allocation, that prevent the program to run but I am not sure if I am wright and also what is the remedy.

What are the optimisation parameters in SES ? In release mode, the options for code generation is already set to : optimize for size. What else can I play with ?

For now, I will use the Debug version with NRF_LOG_ENABLE and NRF_LOG_BACKEND_RTT_ENABLED disable. My program will run on a battery powered nrf52832 module and use ESB communication/DFU.

Hex files cannot contain debug symbols. These can be found in the elf file.

Which optimization is enabled in release mode? GCC "-O3" unrolls loops.

I recommend looking at the map file for actual flash (and other address space) usage.
