CC2640R2F: CC2640R2F

Part Number: CC2640R2F

Hi,

I'm trying to implement On-chip OAD support for my custom board based on CC2640R2FRHBR.

So what I understood is we should have 2 applications, one is persistent App which has OAD service and other is User App which is our custom App.

I tried flashing through OAD and it worked.

I have implemented watchdog in my Custom user app, so in case if my code stuck in between due to some software problem then the boards resets and everything will work normally.

But now the problem is if board resets then seems like the user app is erased and Persistent App is loaded.

So please help me solve this issue.

Thanks in advance.

Hi Madhu,

The BIM determines which app will run at reset. You could try setting your BIM project Debug Configuration to debug without downloading (go to Debug Configurations and under the Program tab select "load symbols only" and try to see which program it decides to run after reset and why (because you could step through the BIM code this way without erasing/reprogramming the part which could affect the behavior you are trying to diagnose). I hope this can help you find a clue to what state your part is in when this has happened, and if the user app is truly erased (you could check Memory view).

Regards,
Katie

Hi Katie,

Thanks for your help. I got to know the flow of this.

Need one more help. Do you have any examples for developing OAD support for cc2640r2f in Android app ?

Thanks in advance.
