#nvs can someone clarify how to traverse NVS? #nvs

Ruben Kertesz

#1637

I would like to use the NVS with the nrf9160 for remote logging. Specifically I don't understand how to track latest read and latest write at the same time.

I want to be able to write 5 values (time stamp and four readings) to a ring buffer in flash each time we take a measurement. I was thinking that the way to do this is to use 5 IDs and then use an index to track the latest successful read + upload. When I am connected to the internet I will read all five IDs for each measurement interval and send them to the server . The issue is that I don't want to send all of the recorded data to the server if for example the first hundred records that are stored in the ring buffer were already successfully uploaded and there are only 20 remaining measurement intervals that need to be uploaded.

Am I going about this the wrong way? Does anybody have any expertise that they can offer in terms of how to index the saved measurements and then the traverse the index using something like a read pointer and a right pointer?

Speaking of, the point of all of this is that I know the sensor will sometimes be configured to log locally and only upload data every hour, 2 hours, 3 hours, etc. I would rather not clear out the buffer every time I upload data in the event that something else goes wrong, like data loss on the server. it's nice to be able to go to the physical device and retrieve locally logged data if needed

GPIO support on nRF52840 DK

Leonardo Molina <leonardomt@...>

#1635

Hello everyone,

Can I access (read/write) a GPIO that is not an LED or button listed in the "Connections and IOs" section of link below?

https://docs.zephyrproject.org/latest/boards/arm/nrf52840_pca10056/doc/index.html#push-buttons

I read in that page that "Other hardware features are not supported by the Zephyr kernel." but (since I am a newbie in embedded devices) I am not sure if that means that "only buttons 1 to 4 are supported and no other GPIO" or else refers to more abstract features (e.g. Enhanced ShockBurst).

Here's the context of my question:

I am editing the example code samples/basic/button to use a GPIO pin that is different from BUTTON 1, 2, 3 or 4 to trigger the button_pressed callback.

I changed

#define PIN DT_ALIAS_SW0_GPIOS_PIN

... to ...

#define PIN 33

and the callback is never called when I toggle the logical state of that pin in the board (from ground to 3.3V nor VDD).

I am not sure if this makes sense if I am using Zephyr, but in the nRF's SDK, GPIO P1.01 of the development board is mapped to 33:

nRF5_SDK_15/components/boards/pca10056.h

#define ARDUINO_0_PIN

This is my very first question on a public list/forum ever (...as far as I recall) so please forgive any mistakes in terms of posting rules, etc.

Thanks for your help!

FIY the mesh message received by the proxy node is a buffer that I add retrieve using net_buf_simple_add_mem function. You need to configure proxy filtering to tell the proxy what addresses your proxy client is interested in. See section 6, and 6.4 in particular in the Mesh Profile Specification. There are many apps that can already do this, such as meshctl from BlueZ and nRF Mesh from Nordic (available both for iOS and Android).

West flashing very large images to nrf52840

Lawrence King

#1625

My code has finally grown over 512k. I am programming the nrf52840_mdk board:

BOARD=nrf52840_mdk

When attempting to program the nrf52840 the flash operation fails because the -t parameter emitted by west is incorrect. West flash does the following:

runners.pyocd: pyocd flash -e sector -a 0xc000 -t nrf52 <path>/build/zephyr/zephyr.bin

as you can see west sets “-t nrf52”, this works great as long as you don’t overrun the 512k of code (the nrf52832 limit) into the flash, beyond which pyocd (or nrfjprog) will complain that there is too much code.

West should set the -t parameter to “-t nrf52840” for nrf52840 boards.

Current workaround is to manually run pyocd or nrfjprog with the correct -t parameter.

West flash annoyance (signed images)

Lawrence King

#1624

It took me a while to figure out my problem with west flash.

After building regular zephyr app, you can simply call ‘west flash’, and west happily does the right thing, it gets the image passes it to the runner, the file gets flashed onto the board and it runs. All is good.

Then I started to build files to run under MCUBoot. West happily builds the image, and west happily signs the image when you run the right command and give it a path to the key:

$ west sign -t imgtool -- --key ~/rc-demo/mcuboot/mykey-rsa-2048.pem --version 1.2

Generating: /home/lawrence/zephyrproject/zephyr/samples/subsys/mgmt/mcumgr/smp_svr/build/zephyr/zephyr.signed.bin

Generating: /home/lawrence/zephyrproject/zephyr/samples/subsys/mgmt/mcumgr/smp_svr/build/zephyr/zephyr.signed.hex

West starts with the image file, and generates two new signed files, just as one would expect

Then things go bad(ish). I politely asked west to flash the signed file

$ west flash --hex-file zephyr.signed.hex

-- west flash: rebuilding

ninja: no work to do.

-- west flash: using runner pyocd

-- runners.pyocd: Flashing Target Device

[====================] 100%

0018045:INFO:loader:Erased 131072 bytes (32 sectors), programmed 131072 bytes (32 pages), skipped 0 bytes (0 pages) at 7.46 kB/s

You would expect west to go fetch the signed file and pass it to the runner, and it sure looks like it did, there is even enough of an image signature that mcu boot thinks there is an image in the primary slot. But mcuboot says the image is not valid.

***** Booting Zephyr OS build zephyr-v1.14.0-2977-g8622c3415d2f *****

[00:00:00.052,490] <err> mcuboot: Unable to find bootable image

It took me the longest time to figure out that west did not do what I had expected:

$ west --verbose flash --hex-file zephyr.signed.hex

ZEPHYR_BASE=/home/lawrence/zephyrproject/zephyr (origin: env)

-- west flash: rebuilding

ninja: no work to do.

-- west flash: using runner pyocd

-- runners.pyocd: Flashing Target Device

runners.pyocd: pyocd flash -e sector -a 0xc000 -t nrf52 /home/lawrence/zephyrproject/zephyr/samples/subsys/mgmt/mcumgr/smp_svr/build/zephyr/zephyr.bin

[====================] 100%

Why would west send the unsigned file? Why would west send a bin file when I requested a hex file. At the very least west could complain that it couldn’t find the hex file. Instead west silently does the wrong thing.

The work around is:

$ west --verbose flash --hex-file build/zephyr/zephyr.signed.hex

ZEPHYR_BASE=/home/lawrence/zephyrproject/zephyr (origin: env)

-- west flash: rebuilding

ninja: no work to do.

-- west flash: using runner pyocd

-- runners.pyocd: Flashing Target Device

runners.pyocd: pyocd flash -e sector -a 0xc000 -t nrf52 build/zephyr/zephyr.signed.hex

[====================] 100%

0017210:INFO:loader:Erased 4096 bytes (1 sector), programmed 4096 bytes (1 page), skipped 126976 bytes (31 pages) at 7.92 kB/s

As you can see, the runner only had to reprogram the signature in the last page. And mcuboot happily started the image which it is running as expected.

In an ideal world west should know that I needed to sign the image (based on the setting “CONFIG_BOOTLOADER_MCUBOOT=y” in the prj.conf file), and should by default send the signed image to the runner. Of course west will need to know where the keys are, and determine if the code should go into the primary or secondary slot.

Re: Cmake and DTC Version issues installing Zephyr

Lawrence King

#1623

Dear All:

Charles has updated the instructions on the getting started guide. I have followed these instructions carefully on a 'new' Virtual Machine'. The instructions work on Ubuntu 18.04 and 19.04 as written, at the time I tested them (Around July 31st). Of course we are in an ever evolving world, Lunix, and Zephyr are always changing so just because the instructions are currently working doesn't mean they will always work, but at this time I am satisfied that they do work as written.

Thanks  to Charles for the updates to the getting started guide.

Hi All,

I was having similar issue: west was failing, probably because there were several revisions: a default one and bootstrapping one. I switched default to the same revision as bootstrapping and it did help.

$ pip3 install --user west==0.6.0

Hi Marti

Thanks you for looking at my problem report.

It turns out I am not the first person to report a version problem with DTC, tsai.eric.h@gmail.com reported the same problem 10 days ago.

I had actually done a 'west init', I just missed writing that in the 
step-by-step. (see my own follow up email where I mentioned this.)

I do know how to work around the cmake (and DTC) version issues, the issue is the getting started guide doesn't tell me I need to do this. 

According to the west team posts the bootstrapper has been deprecated, so I was going direct to the source rather than what is in the getting started guide. 

The location of zephyr is where the 'latest' west put it. I didn't do a git clone, just west init.

In general the getting started guide needs update and (re)testing. Build a new VM with 18.04 LTS and follow the getting started guide, it won't work. But it will work fine with a 19.04 system. 

Fortunately I see Charles is in the middle of updating the getting started guide so I am sure this will all be fixed in no time....

I'll try following the getting started guide again tomorrow.

Today I wanted to ensure that my documentation on how to rebuild my code was complete and correct. I setup a new virtual machine with Ubuntu 18.04 LTS (which is the most recent LTS version available). I then install Zephyr following (mostly) the instructions in the getting started guide, followed by pulling my code from my local git and then attempting to build.

This is where things go bad.

First problem is west wants to build with cmake newer than 1.13.3, 
but the 'default' cmake in 18.04 LTS is much older, I was able to 
work around this by removing cmake, and installing with pip3.Yes, Zephyr requires a recent CMake. Since you're on Ubuntu, you might want to check out the official cmake apt repository from KitWare, which does support 18.04.

https://blog.kitware.com/ubuntu-cmake-repository-now-available/

The 'latest' zephyr (actually west and cmake) insists that I need a 
device tree compiler with version  1.4.6, unfortunately the latest 
is version on Ubunti 18.04 is 1.4.5 (see
https://launchpad.net/ubuntu/+source/device-tree-compiler) hence I 
can't build. OK, to work around this I went into 
zephyr/cmake/host-tools.cmake and changed the MIN_DTC_VERSION to 
1.4.5. OK, I am past this...This isn't a west or a CMake requirement, in my opinion, but is instead a requirement based on the contents of the zephyr DTS files.

Since you're on Ubuntu, if you're building with the Zephyr SDK (which you seem to be), you should have all the host tools you need from there.
This includes a recent enough DTC.

I would not recommend manually overriding the CMake version enforcement checks for the dtc binary.

But things continue to be bad. The next issue I hit is cmake can't find the file zephyr/cmake/toolchain/zephyr/0.10.1/host-tools.cmake and when I look, sure enough the file isn't there. In fact the directory isn't there. There are directories for 0.10.0 and 0.9.5, but I installed zephyr tools 0.10.1 so I am not sure why the directory is not there, and more importantly why is cmake even looking there?.

Here is a 'step-by-step' of the process I followed after bringing up 
a new Ubuntu 18.04 box:This appears to be missing some steps. In particular, it doesn't show how you got the zephyr tree itself. Given that it's in ~/zephyr instead of something like ~/zephyrproject/zephyr, I suspect you didn't do a west init + west update. Is that the case? If so, I'd recommend trying again, but following the instructions in the getting started guide. Zephyr without west is possible, but harder to do correctly.

west updateOut of curiosity, why are you building from the latest west master instead of running "pip3 install --user west" as recommended in the getting started documentation?

At this point I checkout my code from git and try to build, but it 
fails just as well on the blinky program.Based on the above (and the below output) it seems like you might have done "git clone https://github.com/zephyrproject-rtos/zephyr" or similar. This leaves out all the other modules.

I also don't see any mention here of installing the python packages in zephyr's scripts/requirements.txt, which is also mentioned in the getting started guide.

Please try these steps and holler if you continue to have problems:

Re: Cmake and DTC Version issues installing Zephyr

#1621

Hi All,

I was having similar issue: west was failing, probably because there were
several revisions: a default one and bootstrapping one. I switched
default to the same revision as bootstrapping and it did help.

$ pip3 install --user west==0.6.0

Best regards 
Andrei Emeltchenko

Hi Marti

Thanks you for looking at my problem report.

It turns out I am not the first person to report a version problem with DTC, tsai.eric.h@gmail.com reported the same problem 10 days ago.

I had actually done a 'west init', I just missed writing that in the step-by-step. (see my own follow up email where I mentioned this.)

I do know how to work around the cmake (and DTC) version issues, the issue is the getting started guide doesn't tell me I need to do this. 

According to the west team posts the bootstrapper has been deprecated, so I was going direct to the source rather than what is in the getting started guide. 

The location of zephyr is where the 'latest' west put it. I didn't do a git clone, just west init.


In general the getting started guide needs update and (re)testing. Build a new VM with 18.04 LTS and follow the getting started guide, it won't work. But it will work fine with a 19.04 system. 

Fortunately I see Charles is in the middle of updating the getting started guide so I am sure this will all be fixed in no time....

I'll try following the getting started guide again tomorrow.

Today I wanted to ensure that my documentation on how to rebuild my code was complete and correct. I setup a new virtual machine with Ubuntu 18.04 LTS (which is the most recent LTS version available). I then install Zephyr following (mostly) the instructions in the getting started guide, followed by pulling my code from my local git and then attempting to build.

This is where things go bad.

First problem is west wants to build with cmake newer than 1.13.3, but 
the 'default' cmake in 18.04 LTS is much older, I was able to work 
around this by removing cmake, and installing with pip3.Yes, Zephyr requires a recent CMake. Since you're on Ubuntu, you might want to check out the official cmake apt repository from KitWare, which does support 18.04.

https://blog.kitware.com/ubuntu-cmake-repository-now-available/


The 'latest' zephyr (actually west and cmake) insists that I need a 
device tree compiler with version  1.4.6, unfortunately the latest is 
version on Ubunti 18.04 is 1.4.5 (see
https://launchpad.net/ubuntu/+source/device-tree-compiler) hence I 
can't build. OK, to work around this I went into 
zephyr/cmake/host-tools.cmake and changed the MIN_DTC_VERSION to 
1.4.5. OK, I am past this...This isn't a west or a CMake requirement, in my opinion, but is instead a requirement based on the contents of the zephyr DTS files.

Since you're on Ubuntu, if you're building with the Zephyr SDK (which you seem to be), you should have all the host tools you need from there.
This includes a recent enough DTC.

I would not recommend manually overriding the CMake version enforcement checks for the dtc binary.


But things continue to be bad. The next issue I hit is cmake can't find the file zephyr/cmake/toolchain/zephyr/0.10.1/host-tools.cmake and when I look, sure enough the file isn't there. In fact the directory isn't there. There are directories for 0.10.0 and 0.9.5, but I installed zephyr tools 0.10.1 so I am not sure why the directory is not there, and more importantly why is cmake even looking there?.

Here is a 'step-by-step' of the process I followed after bringing up a 
new Ubuntu 18.04 box:This appears to be missing some steps. In particular, it doesn't show how you got the zephyr tree itself. Given that it's in ~/zephyr instead of something like ~/zephyrproject/zephyr, I suspect you didn't do a west init + west update. Is that the case? If so, I'd recommend trying again, but following the instructions in the getting started guide. Zephyr without west is possible, but harder to do correctly.

# cmake must be version 1.13.3 or better!
cmake --version

sudo -H pip3 install git+https://github.com/zephyrproject-rtos/west
west updateOut of curiosity, why are you building from the latest west master instead of running "pip3 install --user west" as recommended in the getting started documentation?


At this point I checkout my code from git and try to build, but it 
fails just as well on the blinky program.Based on the above (and the below output) it seems like you might have done "git clone https://github.com/zephyrproject-rtos/zephyr" or similar. This leaves out all the other modules.

I also don't see any mention here of installing the python packages in zephyr's scripts/requirements.txt, which is also mentioned in the getting started guide.

Please try these steps and holler if you continue to have problems:
