Target not run after flashing

nguyenhung — Wed, 03 Apr 2013 07:37:21 GMT

Hi everybody,

In codewarrior, i have use 'Flash file target' function to flash target. But target does not run after flashing (even do press reset button). I have to unplug power supply and then everything is ok.

Anyone can explain what happened?

Im using CW10.2 and Multilink universal FX debugger of PE micro.

Thanks a lot!

The BDM may be holding the reset line low.

Try unplugging the BDM after flashing.

Hi Jim Donelson,

In my design, JTAG' reset pin is not connected to Target's reset input.

Normaly, must do reset action after flashing. But in this case is not such. I have to do uplug and plug again power cable so that target can run. If I connect my target to PC via RS232, it seems noisy data (or zero' value) transmitted forever. And my target is blocked in that state.

Does the reset button work after cycling power?

Exactly how are you connecting the PC via RS232?

Hi Nguyen Hung.

Can you check in your project "Properties->ARM Linker->Input" the next thinks:

1) Linker command file is intended for your MCU: ..../MK60DN512Z_flash.lcf is intended for K60 (512K ROM/512K RAM) MCU, etc.

2) In "Entry Point" field you have any label name: __thumb_startup (for example). This is a ivINT_Initial_Program_Counter are placed in your vectortable in the address 0x01. Check that this label the same as in the vectortable (in kinetis_sysinit.c file).

3) If you work with RAM "flashing" (check that in the "Run/Debug target" is RAM or Flash) and you haven't enought RAM memory your program will not run.

4) If you try to print by "printf" any debug/Log information in the Console window, your program will crash every time in the first occurence of this operation: close all "printf".

Have a good day.
