I solved the issue. The size should be multiple of 4096 (sector
size). An other problem that I am facing is that when I run the
lwm2m-client over openthread and the last address of the program
is 0x591f3 (the first address is 0x0) if I erase a random sector
(after the last address) of the memory using pyocd i.e pyocd
erase -t nrf52840 --sector 0x64000, I observe that the
client loses the connection with the server. Is there any bug or I
am missing something? Are any credentials stored somewhere in
flash? Thank you On 10/16/20 2:20 PM, Nikos Karamolegkos

Does zephyr only supports PSK for the DTLS (e.g echo client,
lwm2m client). I haven't seen anything about RPK using ECC. On 7/20/20 5:48 PM, Stefan Hristozov

Ok, found the issue:
It was do to pin mapping naming. I was assuming that the pinmaps in Arduino D5, D6, and so on, corresponded to a direct GPIO map, so D5->GPIO_5 and so on... and that's not true. After using the correct pin number on Zephyr, it works as it should.

Have you done the initialization by running gpio_pin_configure with GPIO_OUTPUT_ACTIVE as third argument ? Just to be clear, you´re trying to set pin p0.05 ? That´s located on chip pin7 (QFN48 pkg) ? Chip pin 5 is routed to p0.03. Med vänlig hälsning Erik Englund Innoware Development AB Hyttvägen 13 73338 SALA Org.nr. 556790-2977 www.innoware.se

Hi, No MCUBoot.
toggle quoted messageShow quoted text
And yes, the board boots correctly and I can use GDB to debug. I can see the GPIO driver calls, the values that are set and so on. My prj.conf file is as simple as it can get: CONFIG_GPIO=y nothing else. If I flash for example the BT beacon example, it works fine, so not probably not an issue with the board. I've tried anything more complex, since I'm stuck with the simpler case :) An example of the debug session:
84 gpio_pin_set(gpio_dev, led->gpio_pin, 1);

Are you sure that your board boots correctly? ( debug through gdb or just simple serial output ) What version of the SDK are you using? Is MCUBoot activated in your prj.conf?

Not sure if I'm going to have any help on this, but anyway:
I've a standard NRF52832 module that has connected to pin 5 a red LED. If I flash the module (through JLink) with the Arduino framework, the led blinks without any problem. So there isn't a hardware issue. Since the module is not a standard supported board, but it's a common supported processor, for using zephyr I've chose a similar board either the nrf52832_mdk or another that uses the same processor, created an overlay file to point the default LED to the correct pin and port (Port 0, pin 5), and flashed the blinky sample example. It didn't work... So I've checked several different based NRF52832 boards, checked that there was no pin conflicts on the DTS, only had enabled the CONFIG_GPIO=y on the prj.conf file, but nothing works. Flash it with the Arduino framework for the NRF, the link blinks. Also flashing, for example the Zephyr BLE beacon example, works without any issue, so it seems I'm missing something crucial on the GPIO front. I've tested with several different flags, like GPIO_OUTPUT, GPIO_OUTPUT_HIGH and so on, but nothing works. So... any ideas of what I'm doing wrong, so that this simple GPIO is failing?

THen when I go to <pathto>/zephyr-stuff/testapp/build/qemu_cortex_m3 and do make or make run it tries to #include <core_cm3.h> and complains that there is no such file or directory.

Hi all:
Just wanted to see if anyone can confirm that we shouldn't expect USB Host mode support in 2.5.0, and that it's not in the works. I found an old issue from May 19th that seems to indicate that is the case (https://github.com/zephyrproject-rtos/zephyr/issues/25442). I have been scouring through the PRs since then and it doesn't look like anything related to that functionality has been committed. Thanks in advance.

introducing new delayable work API
Peter A. Bigot
I've been asked to request input on "kernel:
workq: introduce delayable work" (#28891), which introduces
a new API for supporting delayable work queue submission that
cleans up some of the difficulty with correctly using the existing
delayed work API.
"cleanup of work queue APIs and behavior" (#28579) (already merged) documented the problems with the existing API and states an intent that it be deprecated. The problems with that API are not in dispute, only whether existing use in-tree meets the fairly strict requirements necessary for it to behave in a predictable matter. For the cases I looked at it's not clear that they do. The existing version of #28891 includes some deprecation commits intended as examples and verification. These are intended as demonstration, and if there are concerns they don't meet the specific needs of those uses will be extracted and submitted as new PRs when the core functionality is integrated. Please provide feedback on issue 28891 on github. Peter

BLE one central_hr connect two peripherals
#ble
mfinmuch@...
I am using zephyr 2.4.99 to develop a BLE program
Currently, I used central_hr and peripheral in the sample to load separately on two nrf52840s
Now the two boards can communicate with each other, can read and write
But now I want a central_hr to connect to more than two peripherals, but when I loaded the peripheral to the third board, my central_hr could not be connected to the second peripheral
In addition, I also added CONFIG_BT_MAX_CONN=3 in prj.conf, but it still doesn’t work.
I started_sacn() again after finding the UUID
However, after scanning, it will be found that the handles of the two peripherals are the same, and the central request will cause conflicts when reading, so how do you distinguish when the central wants to read data from one of them? Or is there a sample program for one central to multiple peripherals? Thanks, Poyi Lin

Store DTLS credentials independent to the binary
#networking
#flash
#dtls
#nrf52480
Nikos Karamolegkos
Hello everybody, I would like to ask you if it is safe to use these functions in order to store and get DTLS credentials on the device? I would like to make over the air update so I would like the transmitted binary to be independent of the DTLS credentials. An other idea may be to create a different partition for the credentials. What are your thoughts?
Thank you

Nordic 52840 as client Exchange MTU Request Not Supported
Eric Cooper <ericcooper2005@...>
Hi Zephyr Team, I am relative newby to BLE and Zephyr so forgive me if I am missing something obvious. I have a 52840 with the Zephyr firmware acting a client communicating with a Nordic device. If the device sends an Exchange MTU (for 247) a btmon trace shows a response of Request Not Supported (and could this be a bluez issue?). In the same setup if the client then sends an Exchange MTU Request it appears to be successfully acknowledged but going forward the data is sent from the device in 23 byte MTUs as opposed to the preferred 247. If the device does not send an Exchange MTU request and the client side sends the Exchange MTU request the device does properly use the larger MTU. So two issues: . the client does not support Exchange MTU request (Zephyr or bluez issue?) . given a rejected Exchange MTU request from the device (server) and an accepted MTU from the client to the device the full MTU size is not utilized. And as I think about it this could be an issue on the device. A trace is at the end of this email. Thanks in advance and please let know if there is more information I can provide.

ESP32 Dual core - getting started
Dear All:
I have started a new project based on ESP32.
To start I wrote boards files for the ESP32-CAM board and defined a single LED as a peripheral. I was able to compile the blinky sample, flash it to the board and have it start up at board power on. Great! I should mention that the ESP32-CAM board is a single core ESP32, and download is over the serial UART.
Now moving on to bigger and better things, I received a ESP32-WROVER-KIT board. This board has UART and JTAG debug on board and a dual-core CPU. I created a boards file(s) for this board (similar to the ESP32-CAM dts). I managed to get the esp variant of openOCD setup, it seems to download code to the board over JTAG correctly. Unfortunately when I reset the board it doesn’t run my Blinky code, it runs whatever was programmed in the board when I got it.
I think I have two issues, 1) which core is zephyr supposed to run on (cpu0 or cpu1), and 2) what address should the code be loaded to so that it will start at boot time?.
Here is the output of “west -v flash”:

shutdown command invoked
It looks like it wrote Zephyr to the chip (at address 0x40080000), and scribbled something at 0x3ffb0000. But when I restart the board the blinky code doesn’t run.
The serial terminal output shows it startes something else:
