For a project, I am trying to establish what the reset concept is on the Argon/Boron. Looking at the Boron schematic: boron-v1.00-schematic.pdf I see the nRF can pull the UBLOX reset line, and the RST pin only pulls the nRF reset line, so I need to se what the SW…

@thrmttnw , that is one approach taken by other members. Some members are using a TLP5010 watchdog chip like this: [image] Boron / Xenon / Argon Carrier for Outdoor Applications Project Share All, I will be creating a carrier board for the Boron to support outdoor use. He…

There is no code run when the /NRF_RESET pin on the nRF52 is brought low. It’s a hardware reset of the MCU. There is no software cleanup done before reset.

I am looking for what happens in SW when the nRF starts up after the reset?

Ok, let me narrow it down a bit. I am not familiar with the source code and so this may be a completely stupid question, but I was hoping not to have to install the whole build system and all sources to find this info. I am interested to know what peripherals are reset by the SW running on nRF, whe…

@thrmttnw , the initialization code is most likely done by the Nordic SoftDevice software stack (which also includes FreeRTOS) so it won’t be obvious. I’m not sure the source code is in the Particle DeviceOS repo so you would need to download the SDK from Nordic to get to the source code.

Thanks, In that case I am not finding out what happens when the RST pin in pulled on the Boron, other than the nRF itself is reset. I was hoping more info was available without going through the full code base. An alternative then is to design in a reset IC to instead pull the Boron EN pin for lon…

Where in the source can I see what happens when RST pin is invoked?
