Re: How to disable optimization in sanitycheck
alberto.piedras@...
> 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

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.

Re: How to enable DMA transfers for UART?
Li, Jun R
Stefan,
I've ever implemented a DMA-enabled UART on STM32F4 boards, but based on much old version of zephyr. I can try rebasing it to the latest zephyr if you are interested.

[Bluetooth mesh]How can I change device name at runtime in ./sample/bluetooth/mesh/?
Kai Ren
Hello, I’m using Zephyr v1.12.0 release, the sample code I used is ./sample/bluetooth/mesh/. In this project, I know the device name (used at provisioning phase over PB-GATT) is predefined in *.prj file, CONFIG_BT_DEVICE_NAME . Is it possible to change the device name at runtime? I plan to use chip’s factory ID to replace the predefined device name. Thanks.
Best Regards, Kai

Re: LE pair disconnected

Hi Johan, sorry to bother you again. We try to launch Bluetooth service. After typing “systemctl status bluetooth.service” , some error messages as following: Could you give us some suggestions.
Thank You, Tommy From: Tommy Lin (林志聰)
Sorry, I also add bluetoothd file to /usr/libexec/bluetooth/
Thanks Tommy From: Tommy Lin (林志聰)
Hi Johan, Thanks for your information
I do following things: 1. add Bluetooth.service file to /lib/systemd/system/bluetooth.service 2. add bluetooth.conf file to /etc/dbus-1/system.d
and start Bluetooth service , but it is still auto disconnection after connection.
Could you continue to give us some suggestions
Thank You, Tommy
-----Original Message-----
Hi,
The Linux kernel has a 2 second timeout for any connection that doesn’t have users. “Users” in this context are e.g. any user space sockets that use the connection. Normally when bluetoothd is running it owns the ATT socket, so there’s always at least one user. It sounds to me like Tommy might not have bluetoothd or any other GATT server running. Anyway, this is starting to be a bit off-topic for the Zephyr mailing list.
