OpenSDA Programming of KL25Z

[info13]

Hello! I´m using MCUXpresso-IDE + Kinetis SDK to program a FRDM-KL25Z board. Now I have a problem:

When debugging out of MCUXpresso, everything works fine. When I build the program and copy the built *.sxf file onto the "FRDM-KL25Z"-named Flash-Drive, the older software (I debugged before) is executed and not the new one I copied onto the drive. Neither when hitting the reset-pushbutton, nor when repowering the board the new non-debugged software is executed.

The file I manually copy on the board is that one, when looking on the timestamp of the file it is the actual, correct build-version: MCUXpressoIDE_11.0.1_2563\workspace\Testprojekt\Release\Testprojekt.sxf

Anyone has an idea on this behaviour? Am I using a wrong way to program the device?

Kind regards,

Jan Martin

Hi Jan,

None of openSDA version support copy .axf file to target board directly. Please visit OpenSDA Serial and Debug Adapter | NXP , there is a table at the bottom of the page. If your FRDM-KL25 openSDA version is v1, you should generate .s19 file for copy. If the openSDA is V2.2, you should generate .bin or .hex file.

Regards,

Jing

Thanks! Just for interest: What kind of binary is .sxf/.hex/.bin/.s19 ? What´s the difference?

Hi Jan,

not sure where you have seen the .sxf file? Maybe you mean the .axf which is a normal ELF/Dwarf file.

Have a read at MCUXpresso IDE: S-Record, Intel Hex and Binary Files | MCU on Eclipse  which explains the formats for the MCUXpresso IDE where S-Record, Intel Hex and Binary Files | MCU on Eclipse  is a general overview about the different formats.

I hope this helps,

Erich
