Keil Flash programming error in Kinetis MKE14F512VLL16

aman_kumar — Mon, 11 Nov 2019 19:26:41 GMT

Hi All,

I am working on a custom board with the Kintes MKE14F512VLL16 microcontroller. I started out by developing some basic code on the evaluation module (i.e TWR-KE18F) which has the MKE18F xx series part. After my board was ready i am trying to make changes to the existing project to move it to the MKE14F part number. I have made most of the changes to the source code and drivers as needed but i am unable to download the code into my board.

I am using Segger JLink Plus debugger and Keil microvision IDE.

It appears to be some type of project configuration issue pertaining to the RAM allocation. I am able to successfully erase the chip using the same settings.

The error log is below and project configuration screenshots are also attached. Any help will be greatly appreciated !!

Hi Aman Kumar，

Please try your modified project on the TWR-KE18F directly, whether you meet the same problem or not?

TWR-KE18F board can compatible with your MKE14F512VLL16, so if your modified project has no problem, it should also works on the TWR-KE18F board.

If the TWR-KE18F board also have the problem, then we can make sure the problem still in your software side, otherwise, we also need to check your MKE14F512VLL16 hardware.

1. About the code

You can download the SDK for your MKE14F512VLL16

Then, when you open the project, you just need to replace the related file and driver, .s file in folder:

SDK_2.6.0_MKE14F512xxx16\devices\MKE14F16

You can try it.

2. About the hardware

Could you use the JLINK commander to connect your own KE14F board again, can you find the ARM core with SWD/JTAG, when you do the mass erase, can you finish it?

Have a great day,
Kerry

Hi Kerry,

Thank you so much for all of your suggestions !!!

As per your request i tried to program my modified project to the TWR-KE18F board directly and this operation was successful. I was able to see the following messages in Keil window:

Erase Done.
Programming Done.
Verify OK.

I then proceeded to try the JLink commander utility to test the erase operation on my custom board. This also seem to work fine.

The issue however still remains.

Hi Aman,

Please use your MDK project generate the app.bin file, then use the JLINK commander download the file directly on your customer board: loaderfile app.bin 0x00

Please try it, whether no IDE can download the code or not?

BTW, do you have the IAR, if you have IAR, you also can try that IDE download to your own customer board.

Because I DON'T have the MKE14F512VLL16 board, then I can't test directly.

So, you need to test it on your side.

Have a great day,
Kerry

Hi Kerry,

Thank you so much for your response . The JLink commander worked fine and i was able to program the boards with the "loadfile" command.

I got a response back from the team at Keil to make this work and here is the suggestion provided by them

1) Slow down the speed to the interface to 1 MHz (default is 5 MHz)

2) Change the port to SW from JTAG

3) Under Connect and Reset options select "Kinetis"

This allows you to load the code without any issues but you may still have to press the "RST" button on Keil to get the control to main() and then you can proceed with your debug/single stepping etc.

Thank you very much for all your help and hope this helps others who encounter this issue in the future !!

Regards,

Aman
