Commissioning Joiner support for product line nrf52811

[kenval]

Hi, my question is about the commissioning of the thread protocol. Not so long ago I created an ish on the github of the thread project, but with software errors I was offered to write in the devzone
link to this issue: github.com/.../6222

I am trying to implement Openthread for a device on an Nrf52811 controller. I was warned about the lack of 192 kb of memory and the lack of an accelerator module. Nevertheless, the protocol does not take up much space, even a little is left for its software. And the acceleration can be transferred to the program.

I collected a thread as follows according to the instructions from their github
make -f examples / Makefile-nrf52811 JOINER = 1

Why did I start building from source? this is due to the fact that I do not find the otJoinerStart() function in the api thread, I decided to build and compile from resources. As a result of building and slipping libraries, I get errors when compiling GCC

What I've done

Compiled the libraries of the thread downloaded through the git and slipped them into the directory of the SDK Nordic
./openthread/output/nrf52811/lib (folder openthread from github) -> (to) ./external/openthread/lib/nrf52811/gcc (folder SDK Nordic v.4.0)

Hello,

If you want to compile your own openthread libraries, you should use the same commit as the one used in the SDK. This commit is mentioned in:

SDK\external\openthread\project\readme.txt

After checking out the correct commit, it should be quite simple to follow the guide found on infocenter.

That is for building and importing the built libraries. 

I don't know any details on the size of what you are building, but perhaps you can elaborate if it doesn't work.

Best regards,

Edvin

Hi, thanks for the reply!

I changed my tactics a bit using the manual https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_tz_v4.0.0%2Fthread_ot_libraries_building.html
So what have I done so far
1. I downloaded the repository of the thread that is specified in the readm from the github and placed it at 

/compile/nRF5_SDK_for_Thread_and_Zigbee_v4.0.0_dc7186b/external/openthread/project/openthread

2.removed unnecessary boards in the yaml file (import_libs_config.yaml)
3. Added a line like (ASMFLAGS += -DOPENTHREAD_CONFIG_JOINER_ENABLE=1 CFLAGS += -DOPENTHREAD_CONFIG_JOINER_ENABLE=1) to the projects for each makefile

4.compiled with python script (build_gcc_libs.py)

In my project in the makefile, I prescribed the paths where the new thread libraries are located:

LIB_FILES += \
$(SDK_ROOT)/external/openthread/project/nrf52811/openthread/mtd/armgcc/libopenthread-mtd-nrf52811.a \
$(SDK_ROOT)/external/openthread/project/nrf52811/openthread_platform_utils/armgcc/libopenthread-platform-utils-nrf52811.a \
$(SDK_ROOT)/external/openthread/project/nrf52811/mbedcrypto/cc310/armgcc/libmbedcrypto-nrf52811.a \
$(SDK_ROOT)/external/openthread/project/nrf52811/openthread_nrf52811/sdk/spi/armgcc/libopenthread-nrf52811-sdk-spi.a \
$(SDK_ROOT)/external/openthread/project/nrf52811/nordicsemi_nrf52811/driver/armgcc/libnordicsemi-nrf52811-radio-driver.a \
$(SDK_ROOT)/external/openthread/project/nrf52811/openthread_platform_utils/armgcc/libopenthread-platform-utils-nrf52811.a \

I get the following errors yet it is not clear how to be with them can you tell?

I am not sure what happened here, or whether or not you should have "removed unnecessary boards in the yaml file". Did you remove too much?

Did it look like all the builds ran successfully when you ran the build_gcc_libs.py? And have you tried running the import_libs.py with the parameter gcc:

"import_libs.py gcc"?

BR,
Edvin

I managed to compile the libraries correctly. The firmware was successfully assembled and sewn it took about 178 kb. The problem is that the controller hangs .... and the input to the joiner does not work. Maybe somehow you can find a ready-made solution as a minimum to add a joiner to nrf52811?

 What does that mean? What are you observing?

[kenval]

I launch the RTT terminal and see the standard thread version lines and nothing else appears. board reset button does not work....

[Edvin]

Is the main() function in your application reached at all? If it is, in what function does it stop? (try debugging). Or is the issue that you just don't get any serial interrupts?
