s132_nrf52_3.0.0 endless loop at 0x16cbc

[Olaf]

Hello, I'm experiencing frequent endless loops at 0x16cbc with s132_nrf52_3.0.0 softdevice and SDK 12.3 on a custom board with Aconno NRF52832 module. I'm using SAADC and UART peripherals.

SAADC and UART are working with IRQ level 7. As I don't have a tracer available, do you have a hint what is causing the issue?

Hi,

the issue is caused by the SAADC driver. I have disabled the ppi channel and wrote my own sample function using blocking mode. With this setup the software is stable. Nevertheless I will provide an example to reproduce the issue.

Hi,

I am happy to hear that you found have found a workaround!

An example reproducing the issue would be great, as that will enable us to hunt down this bug (it may still be present in the SAADC driver and/or present SoftDevices.)
