IAR compiled bin file size problem [Copy link]

I would like to ask you a question. After I compiled a project under IAR, the code information displayed was as follows: IAR Universal Linker V5.3.2.26 Copyright 1987-2012 IAR Systems AB. 1 894 bytes of CODE memory 184 bytes of DATA memory (+ 44 absolute ) 43 bytes of CONST memory But the size of the generated bin file is 32K. I selected raw-binary in linker->output. What is the reason? Actually, I want to make a remote upgrade program. I am using cc430. The on-chip code space is 32K. If I run the boot program, it will not be enough. Please help me, I will be very grateful. The original program, the bin file size is only 30-40K. After changing part of it, the bin size is 256MB. I can't find out the reason. The chip used is kinetis K10, IAR development environment.

I guess every compilation takes up flash memory, and the original memory will not be cleared, so it becomes larger and there is not enough space.

Use ultraedit or vim to open the bin file in binary format and check whether there are a large number of consecutive 0s. If so, check whether the link script is described correctly.

Thank you for your guidance

The on-chip code space is 32K. If you run the boot program again, after modifying a part of it, the bin space is 256MB. It is this large after modification.

No, create a new project file and compile it.

The configuration file is not the default one, please add the .xcl file correctly again.

Some people say that the reason why the bin file compiled by iar is large is that the link file icf includes a large address range. This project can only be used for online debugging. If you want to generate a bin file to download to the development board, you need to modify the icf file.
