CCS/CC2640R2F: Issues while loading BLE-STACK V3.0 SDK sample projects

Part Number: CC2640R2F
Other Parts Discussed in Thread: CC2650, , LAUNCHXL-CC2640R2, BLE-STACK

Tool/software: Code Composer Studio

Hi everyone, 

I've modified my cc2650 launchpad by soldering on the board the new cc2640r2.

I'm trying to execute some new projects from last SDK released with ble stack 3.0 that compile fine without errors.

The issue is when I select app image, and click on debug to load code on cc2640r2 launchpad, code composer studio give me the error 

Cortex_M3_0: Trouble Reading Register Unknown Register: (Error -2030 @ 0x0) Attempted to access an unknown or invalid register. Confirm the register is valid and accessible, and retry the operation. (Emulation package 6.0.504.1) 

and I can't execute code.

Where is the error?

Thanks in advance for clarifications.

    Hello,

    It may be easier to just use a CC2640R2 LaunchPad (LAUNCHXL-CC2640R2). To rule out any issues related to the rework, I suggest programming the prebuilt simple_peripheral hex file from the CC2640R2 SDK using SmartRF Flash Programmer 2 v1.7.5. If you can't detect the CC2640R2F or program the hex file, then you have an electrical issue with the rework.

    There is a known issue with CCS v7, see the BLE-Stack v3.0 release notes:
    "Debugging CCS v7 projects may generate a spurious “unknown register” error which can be ignored"

    However, this assumes you can program the board successfully.

    Best wishes
