System shutdown unexpectedly

[TeCh_3034126]

Hi,

I am using CYBLE-014008-EVAL for my development.

I made a firmware and ran properly in debug mode (Connected with MiniProg3).

However, when I ran the firmware in 'normal' mode (No connection with MiniProg3), the firmware can only be ran about 3 minutes and the system went to shutdown.

Please help since this issue did not happen if I ran with MiniProg3 debugger.

I also tried to build the blood pressure example and loaded to the evaluation board. It also only ran for about 3 minutes if I did not run with the debugger in debug mode.

Thanks!

Terry

Hi Terry,

Are there any display components on your board? If yes, suggest to use some of these display components as indicators, to help judge where system was stopped/corrupted. And then find solution.

Another suggestion is, at the start of main(), add some code to detect if any unexpected system reset happened .

Thanks,

Ryan
