How can I find out the size of my program and how much program space if left on a K60?

In other environments, finding out how much program space is left is obvious. I am sure the same is the case with KDS. Please enlighten me.

Hi Barry

Look in the console output - it should show you the details. Eg.

Invoking: Cross ARM GNU Create Flash Image
arm-none-eabi-objcopy -O ihex "uTaskerV1.4_BM.elf" "uTaskerV1.4_BM.hex"
Finished building: uTaskerV1.4_BM.hex

Invoking: Cross ARM GNU Create Listing
arm-none-eabi-objdump --source --all-headers --demangle --line-numbers --wide "uTaskerV1.4_BM.elf" > "uTaskerV1.4_BM.lst"
Finished building: uTaskerV1.4_BM.lst

Invoking: Cross ARM GNU Print Size
arm-none-eabi-size --format=berkeley "uTaskerV1.4_BM.elf"
text data bss dec hex filename
43933 196 16552 60681 ed09 uTaskerV1.4_BM.elf
Finished building: uTaskerV1.4_BM.siz

19:12:24 Build Finished (took 20s.755ms)

If you generate a binary file output too you can simply look at its exact size in file explorer.

That is where I thought it would be. Maybe I am not looking at the right console. Is it in there somewhere? I can’t see it. Also, from your example output consule below, how do I know how much program space is left?

Your build is not generating a binary/HEX file - you can check a box somewhere in the settings to get it to use objcpy() to do this and it possibly does the size command too.

In case of problems just call a bat file with command to do whatever is missing; it is more flexible that what KDS offers (the GCC binary folder contains all of the standard utilities to do such things).

The remaining size in Flash is (FLASH_SIZE - code size), assuming you have no areas reserved in Flash for parameter storage or file systems.

Ok, I found an option called print size. Here is what I get.

Invoking: Cross ARM GNU Print Size

arm-none-eabi-size --format=berkeley "x.elf"

text data bss dec hex filename

49892 204 3364 53460 d0d4 x.elf

Finished building: x.siz

I looked at the .elf file in windows and it’s property shows 1.07 MB. The my controller is the Kinetis® K60: 150MHz Cortex-M4F up to 1MB Flash (144pin).

I appreciate your support.

An ELF file contains lots of data (eg. symbol information of debugging) and so has nothing to do with the size of the binary that is loaded (eve small code of a few kBytes may have an ELF of 1 Mega Byte in size).

Configure to generate a .bin output and then you have the the exact size accurate to a byte.
