Inspecting Memory Usage: KL25Z on KDS3.0 ide

nelsonlobo — Sat, 05 Sep 2015 12:21:50 GMT

Hi,

Ive checked the memory and memory browser tab while debugging my code. Also ive noticed that after bulding my app it dis show up some memory distribution of the controller in the console. But after after the second time build it wont show the same. It would be great to see a graphical representation for the same. Is there any option for that???

Regards,

Nelson Lobo

Hello Lobo,

Please check "print size", then build , the code size will show on the console view :

And it seems there isn't graphical representation for the same .

Hope it helps

Have a great day,
Alice

Hi Alice,

I already have that option enabled which provides the following:

'Invoking: Cross ARM GNU Print Size'

arm-none-eabi-size --format=berkeley "1.gpio_setup.elf"

text data bss dec hex filename

12100 188 2116 14404 3844 1.gpio_setup.elf

'Finished building: 1.gpio_setup.siz'

As per my understanding:

text : program/flash memory

data: static ram

bss : ??? (assuming the MCU registers)

is that right??? if not please do correct me.

Regards,

Nelson Lobo

Hi Nelson,

bss is uninitialized data, see text, data and bss: Code and Data Size Explained

I hope this helps,
