Ielftool generated binary file size

[itsme12_01]

Hello,

I used the iefltool to generate the .bin file from .out file. The .out file is only around 400kB in size but the .bin file seems to be over 1000kB in size. Why is the .bin file size very high ? How would I be able to reduce the size ?

Regards.

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
To provide the fastest possible support, I was wondering if you can introduce the steps for replicating the phenomenon.
Have a great day,

Hello, I apologize for the late reply. 
I found the reason for a huge binary file size.
When placing a section into memory, if the segment is divided between two memory regions, then while creating a .bin file, the memory region in between the 2 regions will also be considered. Hence results in huge file size.
For example,
If I place const SECTIONA at 0x2000 to 0x4000
place const SECTIONB at 0x8000 to 0xF000
Then when creating the binary file,
For segment const, the memory region considered would be (0xF000 - 0x2000). The gaps between would be filled with 0s. Hence results in a huge file size.

Hope this becomes helpful to someone in furture.

Thank you.
