First of all my sincere apologies , because this is going to be the biggest question in this forum

I am working on MKE02Z64VLD2 in Kinetis Design Studio Version 2.0.

I am trying to design a boot loader for MKE02Z64VLD2 controller fitted to my customized board. I have configured a switch to be Boot Loader button, if the switch is turned ON, it will enter Boot loader mode. If the switch/button is in OFF state, it will erase the flash blocks and will wait for an application file to be loaded serially through a Terminal Application (Terminal). After fixing all the errors which I faced while building the code, I tried to test it in my hardware. Before testing the code, I just tried to run a simple "LED Blinking code" which serves as my application code in the boot loader. It worked fine. The LED blinked. Then I flashed (using 'flash from file' option of KDS) the Boot loader code into my board. The most famous trace message popped up , "Semihosting process monitor job. java.lang.IllegalThreadStateException" . To verify that nothing had happened to my board, I again tried to debug that "LED Blinking code" in my board. This time it didn't blink and it threw some trace messages, which I have explained in my last part of this question.

Then I did some searching in the internet to fix this semihosting problem.

I found this, As quoted in this article I increased my Stack size to 0x400 and Heap size to 0xAA0.

I optimized the code length also with the help of this article, . Code size got reduced from 5900 to 3616.

Next day, I planned to test my code after doing the above said changes. I powered on the device and connected the J-Link. Suddenly a dialog box appeared. " You are connecting a debugger, which will work only if you unsecure the device. If you click yes, it may perform mass erase of the flash blocks and unsecure the device." I clicked YES. Then I tried to run the "LED Blinking Code" in my board. This time It Successfully Blinked. Then I flashed the boot loader code in to my board. This time it didn't throw any trace messages with respect to SEMIHOSTING. Once I flashed the code, It looked like this.

I thought my code had flashed successfully into board. So I tried to load the application file via terminal application which I use. But it was unresponsive. When I sent an "Erase" command, the display should say " Erasing Flash blocks" instead the display said "<0><0><0><0><0><0>" .

Then I tried to load the Application file itself to check what message comes in Display. But nothing came in the display, it was blank all the time.

To verify that nothing had happened to my board, I again tried to debug that "LED Blinking code" in my board. This time it threw the same trace messages which I fixed earlier.

These are those Trace messages.

To resolve this PE_DEBUGHALT problem, I searched the Internet and found this.

This is how it looks inside vectors.c.

And this is how my KDS screen looked when I pressed the debug button.


Now how to find out which Interrupt is causing the problem from both the figures and how to fix it ?

I even tried to debug a dummy project with nothing written inside main.c. Still I cannot successfully debug. This is how my screen looks when I tried to debug an empty project.

  • I don't know where is the mistake.
  • Whether my code is properly flashed ?
  • I am not getting output for any code, is it because the previously flashed file is still inside my controller ?
  • If it is so, then how to erase the code which is flashed into my controller ?
  • If the flashed code is somehow erased from my controller, will my codes which were working before will work correctly now ?


I have attached the LED Blinking code . If required I'll attach my Boot loader code too..
