unable to load new program

[michaeldobbs]

Hello,

I have done a few demo's with other IDE before. I am hardware engineer by trade.  I am using mcu expresso  toolchain with the FRDM K64F.  I am having trouble terminating the demo programs and loading in another.  The debugger seems to keep running, unable to access the K64 to stop it, and flash in new program. Seems that the debug/download is unable to stop the running application, so that it can grab control  in order to flash new program.   I

What firmware does the OpenSDA debug probe on your board have installed in it? And can you check that you have the latest version of the probe firmware, which you can download from http://www.nxp.com/opensda.

If you still have problems after installing the latest, then please confirm which probe firmware you are using - and details of how you are terminating the debug session, and the exact behaviour you see when you try to start the next session.

Regards,

Hello

Here is what I just did.

Reset by holding down boot button, plugged in, boot folder appears,

deleted existing boot file.

Dragged 0244_k20dx_bootloader_update_0x8000.bin to the folder.

Reset by holding down boot button, plugged in, boot folder appears,

Dragged k20dx_frdmk64_if_crc.bin

Restart MCUXpresso

do build ... OK

do debug ... does not connect "no probes found.

What am I doing wrong?

Hello Michael,

Sorry for the delay reply , how about your question now ?

You needn't change the  bootloder , just drag firmware into bootloader folder,

try to use the P&E or  J-link firmware instead of  "k20dx_frdmk64_if_crc.bin" ,

I attached the two for you .

Have a great day,
TIC
