Hi Team,

I am just getting started with Zephyr and trying to setup development environment. I followed all the steps described to setup ARM GNU GCC toolchain and compilation ENV.
After setting up everything required, I got the following error after trying to compile a sample project.

"
CMake Error at ../../cmake/extensions.cmake:1086 (message):
Assertion failed: The toolchain is unable to build a dummy C file. See
CMakeError.log.
Call Stack (most recent call first):

-- Configuring incomplete, errors occurred!
See also "../zephyr/samples/hello_world/build/CMakeFiles/CMakeOutput.log".
See also "../zephyr/samples/hello_world/build/CMakeFiles/CMakeError.log".

I went through the log files and it seems build failed at following

""
The output was:
1
c:/gnu_arm_embedded/bin/../lib/gcc/arm-none-eabi/7.3.1/../../../../arm-none-eabi/lib\libc.a(lib_a-exit.o): In function `exit':
exit.c:(.text.exit+0x2c): undefined reference to `_exit'
collect2.exe: error: ld returned 1 exit status""

Seems ARM compiler issue, after bit of google found out that these options "--specs=nosys.specs" needs to be passed as command line params to run gcc.
I am not able to figure out where i can exactly instruct build environment to use these command line options for GCC.

I have attached both error and output log.
Any help will be appreciated to be able to compile a project successfully.

Thanks,
Balasubramanyam Rangineni

Subject: [Zephyr-devel] NRF52 Scanning stops without indication




Hi,

We are running continuous active scan on NRF52 with duplicate filtering disabled. Under some circumstances all scan data stops being generated. This has been difficult to reproduce but is a serious bug for our application. It takes thousands of hours of
device run time for us to create and identify this issue. I was able to capture a memory dump of such a device and am trying to examine it for any indication of the problem. I'm looking primarily at _radio state, but if anyone has any pointers I would appreciate
it. The zephyr version that create this dump is master branch as of 10/26.

can zephyr sdk support macos？

Hi Jamie,

You might want to take a look at how MCUboot invokes the reset vector
in an NVIC table after having found the image:

https://github.com/runtimeco/mcuboot/blob/master/boot/zephyr/main.c#L53

As you can see, you can cast the address to a function of the
appropriate type and it does work on nRF52840.

If it's an MPU issue in your environment, the kernel developers who
work on userspace would probably benefit from seeing any relevant
Kconfig options in your build/zephyr/.config file.

HTH,
Marti

The function doesn't do much except update some pointers which are provided to it, however when attempting to run the function from Zephyr, it generates a usage fault error, "Illegal use of the EPSR". I assume this is caused by a kernel security feature, so how would one go about calling an external function generated in a different build environment from Zephyr without it causing a fault?
