Re: ztest and code coverage on actual hardware

Garrett LoVerde
 

I have no extra insight to provide as I've only ever used Mbed OS's on device automated test infrastructure.

But I will say that I plan to get a device test farm running at some point and will need a solution for Zephyr.

ztest and code coverage on actual hardware

lairdjm
 

Hi,
We are trying to get twister working to run zephyr tests with code coverage using real hardware (Nordic-based) but seem to be having issues with this:
  1. The nrfjprog reset does not seem to work - the kernel tests halt when they run the oops function and the `nrfjprog --reset` function does not work when the module is in this state, it seems to only work when using --debugreset and it doesn't look like twister can use this (I've opened a support ticket with nordic on this separately)
  2. With code coverage enabled for our modules in the boards file and running twister with it enabled, tests do not seem to run, the start up code gets stuck on https://github.com/zephyrproject-rtos/zephyr/blob/main/subsys/testsuite/coverage/coverage.c#L273 where it faults, if we enable code coverage with a normal non-test application e.g. hello_world, we see it run and then output the gcov data, if we run the test without code coverage enabled, it works. It only seems to be when both ztest and code coverage are enabled that this does not work
  3. It mentions in one of the MPU files that userspace is required for code coverage but I don't understand the reason for this, e.g. with the hello_world example it is not using userspace and can still output data (I haven't checked the data to see if it's valid or not). This raises an issue because if we try building one of the kernel tests with code coverage and userspace mode enabled, the required RAM is about 300KB - we are aiming to test on modules with 64-256KB RAM so a 300KB requirement is unworkable
Does anyone have ideas for these issues or do code coverage checks on real hardware?
Thanks,
Jamie


DWM1000 driver and TWR

Hi,
Is there any possibility to use Dw1000 driver for two way ranging application? I am asking because this driver supports gPTP for which timestamps is reduced to nanoseconds, which is not enought for precision TOF measurements.

Zephyr SDK 0.13.2 Release

Stephanos Ioannidis
 

Hi,

 

Zephyr SDK 0.13.2 has been released.

 

https://github.com/zephyrproject-rtos/sdk-ng/releases/tag/v0.13.2

 

This release contains several bug fixes and enhancements:

 

  • gcc:
    • Added multilibs for the RISC-V RV32E targets.
    • Disabled MIPS GP register optimisation, which is not supported by the
      Zephyr MIPS architecture port.
  • newlib:
    • Enabled C99 format specifier support for newlib full variant.
  • qemu:
    • Added MIPS little endian emulation
    • Update xilinx qemu to 5.1.0
    • Added Xilinx MicroBlaze little endian emulation
  • openocd:
    • Fixed missing DBG clock on STM32G0/L0.
    • Fixed image verification for ARC.

 

Please try it out and report if you find any issues.

 

Thanks to everyone who contributed to this SDK release.

 

Regards,

 

Stephanos

One more PoC I've poked at as a Zephyr module, making a processing pipeline for sensor data similar to what Noed-Red does conceptually:

Re: Functional Safety Certification

Hibberd, Amber M
 

Hi Thomas,

 

I am the Safety Architect for the Zephyr Project. I set up time with you 11/23 at 9:30 am PST to meet and chat about ZP safety plans.

 

Best,

Hi,

 

Is there some more details about the functional safety certification for Zephyr, or is there someone who can give me some more information?  I'm working with a company that is considering Zephyr for some of it's products but this requires functional safety certification.  Right now, the most promising options are FreeRTOS and SafeRTOS...

clock peripheral zephyr APIs for nordic boards #nrf52

ubaidunited@...
 

Hi,

I need to understand the available zephyr APIs that can let me turn off & turn on the available LFCLK in nordic board.

I found options like:

static inline int clock_control_on(const struct device *dev, clock_control_subsys_t sys)

static inline int clock_control_off(const struct device *dev, clock_control_subsys_t sys)

void z_nrf_clock_control_lf_on(enum nrf_lfclk_start_mode start_mode)

 

I do understand that all of this is done through the configurations in prj.conf.

But i want to know which APIs are responsible for it and how to call those APIs for LFCLK..?

As in if i call clock_control_on( ), how do i populate the arguments *dev and sys..?

Thanks,


Re: Trusted firmware update date

Kevin Townsend
 

Hi Jamie,

We'll have to evalute the complexity of the changes from TF-M, but if there are no major breaking changes to the build system, etc., it should be possible to update for the next Zephyr release cycle. We'll need at least an RC1 or RC2 for TF-M before doing the Zephyr PR, though.

Kevin

Hi,
We have some board file changes to make for when the next release of TF-M is pulled into zephyr, there is an upcoming TF-M release for version 1.5.0 on Monday - will 1.5.0 be used for the upcoming 3.0 release of Zephyr and if so, what is the expected date of pulling it in?
