mkl03z32vfk4 on custom board using processor expert never reaches main

cedrickkukela — Thu, 28 Apr 2016 18:18:30 GMT

Hello,

I am trying to get a MKL03Z32xxx4 running on a custom board. Processor expert generated much code for me but when I test using jlink for debugging, I dont see main(or anything else in my reset vector).

I'm new to processor expert but from the guide i thought that processor expert was suppose to generate the vector and copy it to ram by default. I this is not the case how do i get my code into the reset vector?

I would like for the reset handler to call main when it is done. But there is nothing but ffff in the 0x0 and 0x4. How is this configured with processor expert?

Thank you

When i look at my generated code folder I have the start up files defined. They also have entries in my map file. For what ever reason though I i end up with nothing in my isr. my reset vector does not call the reset handler. Does any one know how to get processor expert to load this. I have included my ld file and map.

Thank you

Hi Cedrick ,

What the IDE you are using with PE? KDS?

I use the KDS create a Processor expert with KSDK1.3.0 for your referece.

You can find the main calling in the startup_MKKL03Z.s, in the startup file, there has a reset handler which calls the main function, just like the following picture:

The project is in the attachment.

Wish it helps you!

If you still have question, please contact me!

Have a great day,
Jingjing

Thank you for your reply,

I do have all the of the start up files and my .S file does have the reset handler. The problem is when i run my application and try to debug it I seem to have nothing in 0x00000000 and 0x00000004. These should be the initial stack register value and pc. Because they are missing my fails to initialize properly. Yes I am using kds with pe. I am all so using jlink on my custom board to read see what is going on.

any suggestions would be welcome. I think i am making a mistake somewhere in my linker settings. I am pretty sure processor expert generates they initial isr.

Thank you

I tried you example and i never hit my breakpoint in main. The device starts up and the vector table but when i click run it just goes into the weeds.

Thank you

Hello,

I am still struggling with this and am just looking for sources of more information. I have my interrupts to fun form internal Flash as well as my code. I think there is something wrong with my linker config or vector table config. Could some out post a working linker config for this processor? I am also looking in to how to set the vector table register. Any info would be appreciated.

Hi Cedrick Kukela,

Do you mean when you run my project directly, and you also can't enter in main? This project just a empty project, and it is working ok on my FRDM-KL03 board.

Could you give me a screenshot where your code stopping?

I wondering whether your hardware can download the code, please give me some problem picture from your side.

Besides, please use the JLINK Commander check your board, whether it can find the ARM Cortex M0+ core.

Have a great day,
Jingjing

Hi Cedrich Kukela,

The vector table already in the startup_MKL03Z4.s.

About the working linker config, you can refer to the KL03 KSDK1.3.0, there has a lot of sample code for your reference, all these sample code is working ok.

Please download the sample code from this link:

Software Development Kit for Kinetis MCUs|NXP

You can refer to the gpio code:C:\Freescale\KSDK_1.3.0\examples\frdmkl03z\driver_examples\gpio\kds

Wish it helps you!

If you still have question, please let me know!

Have a great day,

Yes jlink commonader can see the processor

when i think there is a problem with the binary that is created. when i look at the dis assembly, some sections seem to be left undefined(even for the demo apps).

my isr shows much of the same.

Any advice?

Hi Cedrick Kukela,

I find your JLINK driver is very low, please download the new JLINK driver and try again:

SEGGER - The Embedded Experts - Download

Besides, check these points:

1.Did you try another IDE? Eg, MDK, IAR, and use the KSDK sample code, whether it is still have problem.

2. Please check your hareware, test the NMI pin, whether it is high. did you add 4.7K to 10K external resistor?

3. Send me your test project, I need to test it on myside. It seems that your problem was not caused by the software. We need to find the root problem

Waiting for your reply!

Have a great day,
Jingjing
