ERROR: Can not read register 15 (R15) while CPU is running

Hi, I have FRDM-K64F and FRDM-FXS-MULT2-B boards.

Iniitilally, it works on properly with Freescale Sensor Fusion Toolbox.

To investigate free development enviroment, transfered "OpenSDA v2.bin" to device on BOOTLOADDER mode.

So I found a Jlink CDC UART Port in the device management in WIn7.

To test the freescale sensorfusion example code, I tried downloading into FRDM-K64F (MK64FN1MOVLL12) B/D.

But there were some problems founded from build process such as

Example code : FreescaleSensorFusionRevision5 - FRDM 6DOF Bare Board eCompass(FRDM_K64FKDS)

There are any solution to programming FRDM-K64F ?

Thanks

please refer this document to update FRDM-K64F open source debug interface, then create a new project with wizard to check the connection.

Summary of FRDM-K64F open source debug interface

can this help you?

Have a great day,
