MSP430FR2433: Bin file size is large compared to actual code

A binary file is a flat representation of what is in memory. Since the code is located at the beginning of FRAM and the vectors (including reset) are at the end, a binary file will have to include all of it.

An Intel Hex file (for example) includes address data so does not have to include all of that empty space.

You could reduce the bin file size by altering the memory size in the linker script. An option only if you really need it and understand what you are doing.

Hi David,

I did some trial, but still binary file size is 15KB.

It generated whole 15KB of bin file.

MSP430FR2433 MCU has 15KB of program memory.

Please suggest me where I should change or update.

And ISR address and reset vector outside of the program memory as per data sheet and linker file.

I am using this command to generate the Binary file.

"${CCE_INSTALL_ROOT}/utils/tiobj2bin/tiobj2bin" "${BuildArtifactFileName}" "${BuildArtifactFileBaseName}.bin" "${CG_TOOL_ROOT}/bin/ofd430" "${CG_TOOL_ROOT}/bin/hex430" "${CCE_INSTALL_ROOT}/utils/tiobj2bin/mkhex4bin"

I have charged the FRAM length also for 5KB.

-l msp430fr2433.cmd

So you changed the FRAM length but not where it starts. You changed nothing.

An Intel Hex file,  S records, or anything with address information would be a better way to go.

Hi, David, 

I do not want to change the start address.  Then how to reduce the bin size?

Hex size is 3KB, But i need Bin file for firmware update using custom bootloader.

Thanks,

sumit.

You can't with a flat file format like .bin

Hi David,

I am using this command to generate the .out file to bin file.

"${CCE_INSTALL_ROOT}/utils/tiobj2bin/tiobj2bin" "${BuildArtifactFileName}"  "${BuildArtifactFileBaseName}.bin" "${CG_TOOL_ROOT}/bin/ofd430"  "${CG_TOOL_ROOT}/bin/hex430"  "${CCE_INSTALL_ROOT}/utils/tiobj2bin/mkhex4bin"

Actual code size is 674 bytes.

we used this cmd to check the file size.

/opt/ti/ccs1250/ccs/tools/compiler/ti-cgt-armllvm_3.2.0.LTS/bin/tiarmobjcopy -O binary --only-section .text writeFlash_2.out writeFlash_2.bin

it was giving 604 bytes of .text file.

How to generate the .bin file from .out file?

Is any process available to generate the .out file to .bin file including .text, .bss and .data section?
