System reset while enabling ADC in main loop

Do you receive any error message when it crashes, could you possibly share a log of what is happening during the crash ?

I can take a look at the HW and see if there is anything iffy going on that could be causing trouble for you. If you could share schematics and HW layout files as GERBER file or a Altium file then i will update you with any feedback on the layout.

If you don't want to share the files publicly I can make this case private, just say so and I will make it happen.

Regards,
Jonathan

Updates：

I'm currently using P0.25 as LDO Enable pin. Even if I put the pin configuration in front of main loop, if I switch the status(for instance: set P0.25 as output, pull it high, delay for 100ms, then pull it low), system will crash.

I've also attached enable pin parameters from LDO datasheet.

Hi,

The problem comes from gpio, once I tried to pull the pin high after receiving ble command, system crashed.
