Debugging Bootloader and Application using Kinetis Design Studio

[#1]

Hello community!

Attached is a document that explains how to use Kinetis Design Studio to debug both a bootloader and application at the same time, this will be done using GDB commands to specify an additional symbol file to be used in the debug session.

The bootloader used for this example is the project for the FRDM-K64F board provided in the KBOOT 1.2.0 named freedom_bootloader and the application is a bareboard led demo that was adapted to work with this bootloader by following the steps described in this document:

https://community.freescale.com/docs/DOC-256669

The document was created using the MK64FN1M0VLL12 MCU like the one in the FRDM-K64F board, but the same principles are applicable to any Kinetis MCU.

Software versions

The steps described in this document are valid for the following versions of the software tools:

• KDS v3.2.0
• KBOOT v1.2.0

This was very helpful.

You can do the same thing in IAR by going to the project "Options..." > Debugger > Images and selecting to download and extra image (and optionally to only include debug info).  When you start debugging, you will see all the symbols from both images in the disaasembly window.

Hi Kevin,

Thanks for sharing that information, that method seems to be similar to the one in CodeWarrior where you need to specify an extra executable using the ‘Other Executables’ option, here you can find more detailed information:

Thanks, carlosmendoza‌.

In the pdf there's a reference to P&E only (when inserting another ELF file).

Is there a possibility doing so with Segger?

Thanks.
