Hello and happy v1.12 release candidacy, This is the 21 May 2018 newsletter tracking the latest Zephyr development merged into the mainline tree on GitHub. An HTML version is available

Hi Rodrigo, I am not an expert on persistent storage, but if your system undergoes frequent cold resets then the system will need to write to flash. You may refer to flash API, circular buffer or

Thank you very much. I was taking a look at the NVS system. Let's see if it could solve the problem to me. Best regards, Rodrigo Peixoto Co-founder and Technical guru +55 (82)

Hi Rodrigo, GPREGRET is general purpose retention register in the SoC, which only retains value across warm resets. Refer to

Thank you very much, Vinayak. Any clue on persistent storage and ultra-low power? Best regards, Rodrigo Peixoto. Rodrigo Peixoto Co-founder and Technical guru +55 (82) 98144-8585 http://ayna.tech

Hi fellows,I am developing an application that counts pulses from a source. I need this system to be the lowest power possible. I was wondering if I could use the GPREGRET register do store this

Hi. I Think it will be possible – (but can’t be sure). At last Jehudi Maes (the NVS author) is considering right now ho to provide nvs-back-end for the setting (I’m in touch with him).

Hello All, I am starting to design a driver for PMIC device in Zephyr. I am trying to figure out how to place this driver implementation. PMIC devices usually has multiple functionalities on

Hi Vikrant, Mesh will work with any settings backend (currently FCB and NFFS, and in the future with NVS). Johan

Hi Andrzej, Is #BluetoothMesh stack completely independent from persistence storage mechanism used by #SettingLayer ? If yes, then only it will possible. 😃 Thank You !!

Pawel, this is what I'm seeing in dmesg: [1281987.068423] usb 1-1-port4: unable to enumerate USB device [1281987.760149] usb 1-1.4: new full-speed USB device number 86 using ehci-pci [1281993.003844]

Hi Pawel, The issue with the timeout is a well known one. I think Johann had a proposal, but first we need the stable driver to be on master. Carles From: Zadrożniak, Paweł Sent: 16 May

What does dmesg say? In my case it is detected, but I have noticed 2 issues: selecting alternate interface does not work, so image-1 cannot be flashed image erase takes over 10sec which cause timeout

Hi, will it be possible to choose between #FCB & #NVS for #BluetoothMesh persistence data storage using configuration options ? Thank You !!

Pawel, I tried out the DFU sample on your branch, and I'm not seeing the device show up as a DFU capable device. If I run sudo dfu-util -l it doesn't show up in the list, and if I run sudo dfu-util

Yes Carles, that is what we're trying to do. I've gone ahead and forked the repo so that I can change the reset function to apply the public MAC stored in the UICR.

Hello, This is the 14 May 2018 newsletter tracking the latest Zephyr development merged into the mainline tree on GitHub. An HTML version is available

So let me get this straight, you program the address into the UICR during production, and then you want the controller to read it from there right? In that case unfortunately you will need to

Hi Johan, As per nrf52840_pca10056.dts file last 16KB is used for persistent data storage. To calculate FLASH life time, I have to understand what is going on at background (at #FCB layer). This

Hi Vikrant, The currently implementation is purely based on settings, so you can just register your own settings subpath to store app-specific information. I'd advise to use something else than "bt/"
