Thank you haakonsh for your help. I will ask segger forum and i will inform threre.

Then I'm afraid I'm out of possible solutions. You should ask segger if they've got some tips.

I added both SetRestartOnClose and SetResetType parameters as follow but nothing changed.

Hmm, try adding 'SetRestartOnClose = 1' to common -> debug-> jlink -> additional j-link options.

If that does not work try adding 'SetResetType = 0' as well.

Hi haakonsh, thank you for response. I've added your proposed settings to project. However, the situation does not change.You can see the settings in the picture.

And this is the output.

Also, i can make debug without problem before and after settings. Do you have any other suggestions? Thanks.

Yeah I think you've made the correct calculations after you set the optimization level to 3 in SES. Then it should be very close to GCC with opt lvl 3.

I also believe that level 3 optimizes for both code size AND execution time. It might be that the Keil compiler is set to optimize for code size only(level 1 or 2).

Segger uses GCC as it's compiler, whereas Keil has it's own compiler who's very good, but costs $$$.

I want to fix my error in RAM calculation. I made Heap Size: 1024, Stack Size: 1024 for all compilers and update the results according to this heap and stack size.

Keil creates 41kB hex file. RAM size: 2984 byte ROM Size: 15052byte. (Program Size: Code=14448 RO-data=300 RW-data=304 ZI-data=2680)

I think that real RAM size is equal to (2984 + HEAP SIZE = 4008 byte). Because, I make HEAP_SIZE zero in KEIL but RW or ZI data does not change. (Edit: Enabling MicroLIB removes the HEAP.)

GCC creates 59kB hex file. RAM size: 1824 byte ROM Size: 21368byte. (Program Size: text=21204 data=164 bss=1660 dec=23028 )

I changed HEAP_SIZE and STACK_SIZE in GCC makefile. However, All values(text, data, bss, dec) are same. So, I think that real RAM size equal to 1824 + 1024 +1024 = 3872 byte.

In segger, heap and stack remained same (1024 byte) but i change optimization level as Level-3 and segger creates 57kB hex file and the ROM size changed as follow.

KEIL, ROM:15052 byte, RAM: 4008 byte

GCC, ROM:21368 byte byte, RAM: 3872 byte

SEGGER, ROM: 20,2 kB RAM: 3,7 kB

Now, ROM and RAM size is almost same. Do you think these calculations are correct? Why do segger and gcc create so big hex file? I made something wrong?

Thanks everybody for their response.

Try adding 'TargetInterface.resetAndStop(1000)' to project -> options -> common -> Target Script, as well as adding 'main' to project -> options -> MY_PROJECT -> Debugger -> Run To.
