Re: Get BT MAC addr in zephyr
Hi Tommy,
On 25 Mar 2019, at 6.10, Tommy Lin (林志聰) <Tommy.Lin@quantatw.com> wrote: We use Nordic 51824 with Zephyr 1.13 version.It’s always the responsibility of the host to set the random address. When you do a combined build of Zephyr (both controller and host) the FICR address will be used. However, if you’re running BlueZ as the host, it’s the responsibility of BlueZ to set the random address. There’s no standard HCI command to read the FICR value from the controller. Zephyr does have HCI vendor commands for that, but if I remember right BlueZ does not support those yet. If you don’t care about the FICR address specifically, but just want a fixed static random address, then any recent bluetoothd version (>= 5.44) will generate this for you automatically (that’s the /var/lib/bluetooth/static- file that you referred to).

Get BT MAC addr in zephyr
Tommy Lin (林志聰) <Tommy.Lin@...>
Hi Zephyr, We use Nordic 51824 with Zephyr 1.13 version. By default, the Nordic BLE address is derived from the NRF_FICR->DEVICEADDR[] register. We use “bluetoothctl show” and can get a random mac address. 1.I don’t know if the random mac address is from NRF_FICR->DEVICEADDR[] register ? 2.Every time , the mac address will be different value , if I delete /var/lib/Bluetooth/static-xx:xx:xx:xx:xx:xx folder and then reboot device. I expect the random mac address from NRF_FICR->DEVICEADDR[] register should be fixed , am I right ?
Thanks Tommy

Use GH labels, save time
alpi@...
Hi, Lots of GitHub issues and PRs are being created daily. To help us manage them we have “labels”: to classify them by area, type, priority, or to mark them in need of attention.
When creating a GitHub issue or pull request, remember to add the appropriate labels. It takes a couple of seconds. If you are reviewing a PR, and there is missing or incorrect labels, fix it * This will save us all time when searching, reduce the chances of your PR/issue being forgotten, speed up reviewing, reduce the changes of duplicates, etc.
Best regards, Alberto Escolar Piedras

Re: [Bluetooth Mesh] How is the correct way to make a self provision

Hi Lucas,

One more thing, this messages "<wrn> bt_mesh_cfg_cli: Unexpected App Key Status message" are normal or is missing something?No, that’s normal. It means you used the configuration client API without requesting it to wait for the response messages from the (local) configuration server. In that case the client code considers the responses unexpected since it didn't saved any context for the pending request. Johan

Hi Lucas,
toggle quoted messageShow quoted text
It looks like you’ve enabled CONFIG_BT_SETTINGS, but are not calling settings_load() in your app. It might explain the behaviour you’re seeing, since you’re effectively leaving the stack partially uninitialised without an identity address. Since you mentioned the mesh_demo app, you could e.g. look at where/how it calls settings_load(). Johan

[Bluetooth Mesh] How is the correct way to make a self provision
#bluetoothmesh
#zephyrbluetoothmesh
Hello, I need help to understand what is the correct way to make a self provision. I have two boards(nrf52_pca10040) and them will be provisioned on the same network to make some tests. So far I was using my phone(nRF mesh) to make the provision. However this approach was delaying the development, so I decided use self provision. Reading some examples like bluetooth/mesh_demo I implemented this:
Below I show the necessary elements and srv models to solve my problem: The problem is that when I flashed the firmware I got this: "Advertising failed: err -22" and "Failed to avertise using Network ID" keep happening all the time, in loop. So what I need to do to solve this? @EDIT: err -22 is related to "Invalid Argument" according to the errno.h, but I don't know exactly which one.

Re: How to disable optimization in sanitycheck
alpi@...
> there are signs that there may be optimization enabled
Note that you can check the configuration sanitycheck used in the sanity-out folder, for example for hello_world with native_posix the folder is: sanity-out/native_posix/samples/hello_world/sample.helloworld/zephyr/.config
You can check there for CONFIG_NO_OPTIMIZATIONS=y
You also have the used make/ninja files there.

Dear All
Is there an option (or any instruction on how to modify the code) to disable all optimization in sanitycheck?
Purpose: When I was looking at the code coverage report generated by sanitycheck, there are signs that there may be optimization enabled, e.g., only the middle of three C statements was not covered and the program execution is linear. I was exploring command line option to disable optimization but cannot find any
Then I was not sure whether something was optimized away with "Z_SYSCALL_HANDLER(funcName);" statement, i.e. a syscall handler with empty body
Many thanks in advance Cinly

You may need one extra level of quotation, see --extra-args CMAKE_C_FLAGS example and sanitycheck pointer in https://github.com/zephyrproject-rtos/zephyr/pull/14593/files "test/determinism.sh"

Re: Triggering Z_SYSCALL_HANDLER calls
Boie, Andrew P
You need to call the API from user mode in order to exercise the handler functions. If you call the APIs from supervisor mode, the software interrupt and handler function are bypassed and control goes directly into the implementation function.

Dear All
I am trying to write some coverage test to cover Z_SYSCALL_HANDLERs and I need some clue on how to start. I know I have to set CONFIG_USERSPACE.
Normally for Z_SYSCALL_HANDLER(funcA), gcov reports that z_impl_funcA() were called, but the line Z_SYSCALL_HANDLER() might not be called. This is despite other Z_SYSCALL_HANDLER() are called. I see this in kernel/timer.c where (1) Z_SYSCALL_HANDLER(k_timer_status_get) and z_impl_k_timer_status_get() were both being called, but (2) Z_SYSCALL_HANDLER(k_timer_stop) not called but z_impl_k_timer_stop() was called

Building multiple images
Sebastian Boe
Hi all,
due to how advanced security features (TEE) and device firmware upgrade (MCUBoot) is organized we are seeing the need to boot Zephyr applications in multiple stages. A real-world use-case of even a 3-stage boot process has been identified and tested at Nordic. Each bootloader needs to be individually upgrade-able and have it's own configurations of Zephyr libraries. To achieve this each bootloader must be organized as it's own executable. To make matters worse, in a multi-core AMP system each core would also require at least one executable. The problem is that the build system can only build one executable. This creates a usability issue as the user must invoke a large set of arcane commands to build, sign, and flash each executable. After considering many options we have finally ended up with a solution proposal that is merge-ready. See the PR for details https://github.com/zephyrproject-rtos/zephyr/pull/13672 Please add your feedback in the PR and let us know what you think of the proposed change.
