CCS/CC2642R: Code doesn't run after reset.

I have some custom chips I made that I had OAD application running on (app.oad, persistentApp, and the BIM).. I'm now trying to run the multi role example "no oAD" on these chips. I have used UniFlash to erase the chips many times thinking that the BIM is causing my issue. The multiRole example runs fine right after initial programming, however, when I cycle power its not running. Unfortunately I don't have access to serial on these custom boards I have made but they appear to do nothing until I flash them with the MR example again.

Is there something special I have to do to the chips to get them to work?

Extra debug info: I have a couple of my custom boards that have never been flashed with the OAD, persistent, and bim files. Those do work after power cycle. I have limited chips and need to reuse what I have and struggling here.

Thanks in advance,

Are you sure you download multi_role to your CC2642R custom board not CC2652R on LaunchPad?

Hi Chen,

I did forget to set that, however, after setting it I'm seeing the same issue. Interesting that the code works on chips I've never flashed before. Its only not working on the ones I was running the app.oad, persistent and bim.

In UniFlash under Manual Erase im "Erase entire flash" Does this wipe out the BIM sector as well?

Yes, it would wipe out the BIM sector as well in UniFlash under Manual Erase im "Erase entire flash".

Solved: issue with connected hardware to GPIO that was interfering with boot. Removed custom chip from attached hardware and custom board boots after power cycle.

Thanks Chen for pointing out the use of the correct ccxml file. :)
