error stopping at main. Reason: target request failed: Failed to set breakpoint

ryanlush — Fri, 12 Feb 2016 20:51:37 GMT

I am trying to program a K64 Freedom board with a JLINK and I get this error every time with the option to continue. If I continue it kinda looks like it programs but its way off in the weeds. I can't even see any disassembly and it's halted at what appears to be a random address.

My debugger is setup for SWD with the k64.mem file. I can erase the device with the flash programmer and the same configuration but never have I been able to program the device. Not sure what more information to provide right now. Help me help you help me :smileyhappy:

Which IDE software are you using?

Have you tried with NXP provided demo project for FRDM-K64F board?

Customer could find the NXP provided demo project at KSDK V2.0 or K64 bare-metal project.

Wish it helps
Have a great day,

I am not able to build the example projects I have tried to build. They complain about "orphaned configurations." I was able to create a project with processor expert and debug it on the target. Neither really solved my problem.

I am using the latest Code Warrior IDE

For you could debug the new created Processor Expert project, the debugger interface hardware should be worked.

I checked the KSDK software doesn't support CodeWarrior MCU IDE software.

Customer could download and check with NXP MQX RTOS 4.1.0 for the FRDM-K64F software if J-Link works well with this software.

But I'm not using the KSDK so I don't see how this is relevant.

As it sits I am unable to use the K64 freedom board with Code Warrior but it works with the IAR example projects. I would much rather run my k20 software on the k64 than rewrite the whole thing from scratch. Any help would be appreciated.

Hy Ryan,

you dont' have to rewrite things from scratch. I believe your linker or debugger configuration files are wrong.

I recommend that you start with a new project with the wizard (File > New > bareboard project...) and then verify that this is debugging properly.

Then add the source files to that project.

I hope this helps,

Erich

Wow, you answered my question in 2 places! Thanks!

I have tried using processor expert to setup the bare minimum. When I did it using the freescale compiler I was able to debug when I did it using GCC I was not able to program. The code I want to run on here is written in GCC so this is really what I need to see working.

I always get the "unable to write reg" errors when I try to program so it seems likes its getting stuck in the kinetis_init.tcl script.
