Meaning of the error message

[Y_Chika]

Hello everyone,

I am using FRDM-K64F.

I try to run demo application in debug mode, but  it doesn't run and shows following message in console window:

I have seen quite a few articles in which it states.

I don't resolve this trouble.

How can I run my device?

I am using Kinetis Design Studio IDE v2.0 and GDB Open OCD Debugging.

I have the same problem. The Bootloader is 226. Windows 10. openocd is 0.8.0-dev

K64F Freedom board

Are there openocd commands I can use to permanently unsecure the device.

Restarting the Kinetis IDE did not help. Rebooting did not help. Reconnecting did not help.

Hello Richard,

You can use the PE interface to flash ,  enable "Mass erase on connect", it can unsecured when connect:

First update the bootloader use the firmware "DEBUG-FRDM-K64F_Pemicro_v108a_for_OpenSDA_v2.0.bin",

I attached it .

Hello,

For early examples (hello_world, adc..., etc.) I can already debugging. I don't know how I resolve the problem but now is working.

i don't know if this next question is in this topic, but I create a simple example of make a toggle to a led, when I'm going to debug give me the following error: 

Error in final launch sequence

Failed to execute MI command:

-exec-run

Error message from debugger back end:

Don't know how to run.  Try "help target".

Don't know how to run.  Try "help target".

I try to debug with the option "GDB OpenOCD debugging".

What I need to do to corrct this problem?

Best Regards,

Tiago

Hello Tiago,

Which board?

And have you udpate the bootloader to MBED firmware ?

Alice

[tiagofernandes]

Hello,

I'm using the FRDM-k64F board, and I insert in my board the last version of bootloader, version 226 if I'm not wrong.
