some sensors high current issue during production

[Rita]

We use nRF52832 to develop our sensor.

Then SDK version we used is 14.2.0, and the softdevice is S332(ANT_s332_nrf52_2.0.1)

Now we develop the FW hex file with softdevice and application.

It seems good and the result is as our expected  when we test.

After production, we have the issue which is a few sensor will always reset after wakeup.

It will cause the high current issue.

We found the solution if our FW hex with softdevice , applicaiton and bootloader seems good.

Our problem is why we need to add additaional bootloader hex to our FW hex.

But most  sensor didn't have the problem with only softdevice and applcition.

Thanks for your help.

Hi

So some of the devices are just caught in a reset-loop when trying to wake up on your end if you don't have a bootloader in your project? Can you share some more details on what your application is doing, and how are the memory sections set correctly? Please check out the RAM and Flash memory adjustment guide available here to make sure the memory sections are set up correctly.

Best regards,

Simon

Yes, only some fo the devices. Most devices didn't have the issue.
I have checked the start address as below.

Can you check the address is OK or not?

Hi

These addresses should be just fine as long as the compiler doesn't complain when flashing or logger doesn't complain while running the application. 

If that's not it, there must be something else that is different with the working and non-working boards, so please inspect the faulty ones to make sure they are soldered correctly with a multimeter or similar to make sure they are connected correctly and all components are set up.

Best regards,

Simon
