CCS/CC2640R2F: Bricked the device while re-programming

Harsha B R Rao

Part Number: CC2640R2F


Tool/software: Code Composer Studio

Hello,

I am using custom designed cc2640r2f board for a simple bluetooth application. I programmed the device with my own code using the pin shutdown example, as I wanted to put the device to deep sleep after few tasks, and now I am trying to reprogram the device and I have the following error:

This error is generated by TI's USCIF driver or utilities.

The value is '-242' (0xffffff0e).
The title is 'SC_ERR_ROUTER_ACCESS_SUBPATH'.

The explanation is:
A router subpath could not be accessed.
The board configuration file is probably incorrect.

Any leads on debug?

Also, I have not changed anything with the configuration files, and I am using XDS100v3 for debug.

    Do you use CCS? If that is the case, please check if the selections marked with arrows reflect the chip and type of debugger you are using.

    Are you able to read out the CCFG section using flash programmer 2 to verify that this is as expected? 

    Which flash size do you use and is this reflected in the selected linker file?

    No, that wasnt the problem, the code was blocking reset I think, but i used flash programmer to completely reset the device and its fine now
