The Hex format is universal and thus you don’t have to rely on a particular environment to upload it on to your MCU.

Hi, Kerry – could you say a bit more about the advantage or purpose of converting the code to Hex format before uploading, or the implications of the alternative?

I’m not sure what you mean by “(which means if you will have to rely on the IDE to do your debugging/deployment).”

Thanks, I’m a complete ARM newbie.

Aha, thanks for the info.

To get the HEX output by default navigate Project -> C/C++ Build -> Settings -> Tool Settings -> Other -> Output Format then check convert build output and format to intel hex.

Hope this helps.

Hi Wong,

Thanks for the rewiev and good explanation.
But I you don’t have to use Ronetix Toolchain. It is possible with Atollic Toolchain.
Lite Edition is only blocking generating the .hex file via Atollic IDE. It is possible to over command line.

You can use this while in the command line : arm-atollic-eabi-objcopy -O ihex [project].elf [project].hex
And works ;)

Thanks.
Best Regards.

Hi Alan,

No, it’s not that it couldn’t transfer code, it can. It’s just if you want to use the .hex format, you can’t do it within the IDE.

I’m finding this hard to believe, so I need to verify.

You have a card that plugs into the PC via USB port. That’s how it gets power.
BUT- you say you can’t transfer [compiled] code to the board?
You HAVE to buy the ST-LINK utility hardware device?

Or do you mean – you need to use the ST-LINK software and USB driver at:

to communicate ?

The .elf file would be the one generated using Atollic TrueStudio.

Sure… the tool I used is ronetix-gnutools-arm-elf-4.1.1-linux.tar.bz2 (from http://download.ronetix.info/toolchains/arm/)

and another thing, what and where you mean by saying:

To convert the ELF file to HEX, use the command below:

STM32F4-Discovery_FW_V1.0.1\Project\Demonstration\TrueSTUDIO\STM32F4-Discovery_Demo\Debug

arm-elf-objcopy -O ihex RCC.elf RCC.hex

do you mean in Ronetix or atollic? I think both are using same eclipse?

Hiwa — Tue, 29 Nov 2011 21:19:42 +0000

but I have only the above kit(STM32F4-Discovery) and I want to have hex file after I compile my program using any IDE that I can program in c/c++. can you be more clear please about that tool that I have to download..

Thanks
