Hi Carles,
I am trying to build Zephyr to fit in a memory constrained device of 64kB. My device doesn’t require multithreading and hence I disabled multithreading to save on the memory. However, this is throwing me exceptions since I have UART and SPI Flash drivers enabled. It appears the semaphore accesses in those drivers are not “single-thread” aware. Is there anything that can be done to work-around this? Does just “nop”ing it out suffice? Please let me know.
Regards, Raj

Hi there,
The jlink runner will try to execute a file named “JLinkExe”. This exists on Linux but I just checked my Windows machine and it is named differently, namely “JLink.exe”’. I think we need a patch in the runner to execute a different filename based on the platform.
Could you try renaming “JLinkExe” to “JLink.exe” here: https://github.com/zephyrproject-rtos/zephyr/blob/master/scripts/meta/west/runners/jlink.py#L20
and see if that works.
Thanks,
Carles

Hi,
I have followed the getting started guide and installed zephyr, GNU, and tools on a Windows 7 machine and now trying to build and flash the "hello_world" sample. I'm following the guidelines for the supported NXP FRDM-K64F board. Since I'm using jlink for flashing, which is not default, I use below cmake command: cmake -GNinja -DOPENSDA_FW=jlink -DBOARD=frdm_k64f ..
This command executes without any errors. Then I use below command for making the elf file and flash the board.
ninja flash This also runs without errors until the actual flashing. See output from cmd window below: [103/109] Linking C executable zephyr\zephyr_prebuilt.elf
Memory region Used Size Region Size %age Used
FLASH: 12676 B 1 MB 1.21%
SRAM: 4012 B 192 KB 2.04%
IDT_LIST: 88 B 2 KB 4.30%

Using runner: jlink
Flashing Target Device
FATAL ERROR: 2 The system cannot find the file specified None 2 None
run as "west -v ... flash ..." for a stack trace
I believe all my environment variables are set correct for using GNU compiler: GNUARMEMB_TOOLCHAIN_PATH=C:\gnu_arm_embedded ZEPHYR_BASE=c:\zephyr\zephyr\
ZEPHYR_TOOLCHAIN_VARIANT=gnuarmemb
I can flash the elf file using the J-Flash Lite without any problems, so I beleive hardware and windows drivers are fine. I hope somebody can help me fix this basic issue. Best regards, Bo

Akash Naidu <akashnaiduece@...>
Hi all,
is there any example that supports both central and peripheral roles? I would like to integrate central and peripheral roles into rpl_node example. I have successfully integrated peripheral code, but couldn't enable the central code. could please help me to enable central role (which should support 7 servers)in rpl_node? Advance in thanks. Regards Akash.

How to build images for client or server in bluetooth mesh examples?
#bluetoothmesh
wxzzzh
I noticed that in these examples, there's only one main.c file, and only one image file would be built, it can support different hardware, but seems not different roles?
Bluetooth Mesh is supposed to be run in different roles, right? If one image is enough, how to set it for different roles?

Re: PCA10059 without additional debugger - non-volatile storage of settings

Hi Jamie,

thanks! I was already trying different values, such as storage_partition: partition@b0000 { label = "storage"; reg = < 0xb0000 0x4000 >; }; unfortunately without success.. The display of nRF Connect does not change here, such that it does not show an additional region for the config (I don't know if it is supposed to). Best regards, Martin Am Do., 27.

Re: PCA10059 without additional debugger - non-volatile storage of settings
lairdjm
Hi Martin,
You have this in your DTS: storage_partition: partition@fa000 { label = "storage"; reg = < 0xfa000 0x4000 >; }; You are setting the storage partition to 0xfa000, from your picture, the Nordic bootloader starts at 0xe0000, so yes the settings will never work because you're attempting to overwrite the bootloader. Luckily for you it looks like the bootloader enables write protection using ACL, otherwise it's likely your module would no longer be working. Thanks, Jamie

PCA10059 without additional debugger - non-volatile storage of settings
Martin <ma@...>
Hi,
I know it is a quite specific question, but I thought that maybe someone has an idea into which direction to go.. I have some PCA10059 (nRF52-Dongles) lying around and would like to make experiments with them running Zephyr OS. Unfortunately, I do not have a an appropriate cable for connecting it to my nRF52 DK to flash it and buying a cable would crash my budget. Luckily, work has been ongoing to make flashing the PCA10059 possible without an external debugger. The solution (how I understand it) is that the stock Nordic bootloader remains on the PCA10059, loads MCUboot, which in turn loads Zephyr OS. The merge request can be found here: https://github.com/zephyrproject-rtos/zephyr/pull/11210 I have playing around with it (i.e. flash samples/bluetooth/mesh) and can report that it is working. I had to make two modifications: Comment storage_partition in boards\arm\nrf52840_pca10059\nrf52840_pca10059.dts, such that there is no duplicate collision with dts/common/nrf52840-nrf5-*.overlay and strangely (I would interpret the documention differently) keep Kconfig settings how they are (leave CONFIG_BOOTLOADER_MCUBOOT=n). The "only" problem I have: Storage of settings does not work. The symptoms are that I have to re-provision the PCA10059 every time it is power-cycled. I have been playing around with storage settings in the .dts-files (changing the memory regions) with no success. Attached is the _dts_compiled that is generated during the build phase and a screenshot of nrf connect showing in which regions code resides. Has anyone already gotten storage of settings with PCA10059 to work (possibly even with the traditional debugger solution)? And does anyone have a clue / an idea why it is not working and where I should look into? Thanks, Martin

Hi.
It looks that you have HFCLK running all the time. This is probably caused by small issue in power management code. Please try to remove the calls to nrf_power_task_trigger() from soc/arm/nordic_nrf/nrf52/power.c

Hello, In order to use the peripheral and central device for energy efficient application, I performed some power measurement test with the following configuration using nrf52 DK. Central_hr sample application is used as it is without making any changes. In Peripheral_hr sample application notification time is changed to 1 sec. In menuconfig : · Device drivers: o Console drivers o Serial drivers o GPIO drivers o Use legacy SPI API are disabled · Debugging Options: everything is disabled · Bluetooth: none of the debug option is enabled
The average Current consumption on Peripheral device is 390 μA and average power consumption is 1.31mW with 3.35 V source.
Once the peripheral starts notifying, there are continuous spikes in the measurements between 2 notifications. I also checked with different connection intervals and different notification
periods but still, there are same spikes.

Re: zephyr thread
Raj Gundi
The stack is not allocated in your example when you are using k_thread_create. Use the below code instead.
static K_THREAD_STACK_DEFINE(threadStack1, 1024); static struct k_thread thread1; k_thread_create(&thread1, threadStack1, 1024, (void*)DL_StateMachine_ModeHandler, NULL, NULL, NULL, 7, 0, K_NO_WAIT);
K_THREAD_STACK_DEFINE is called internally if you use K_THREAD_DEFINE instead of k_thread_create,

Hi everyone,
I am currently working on the Zephyr OS with a FDRM_K64f board from NXP.
To create thread I was first using K_THREAD_DEFINE.
I want to create an abstraction layer if I need to use different OS (a platform with generic definition for thread) so I won't have to modify the source code.
Since I can't call K_THREAD_DEFINE inside a function (I was ending up with an error). I am trying to use k_thread_create.
It's working when I create 1 thread but I have error as soon as I am trying to create multiple one.
Here for example I am creating 2 threads:
struct k_thread thread1 ; k_thread_stack_t threadStack1 ;
struct k_thread thread2 ; k_thread_stack_t threadStack2 ;
k_thread_create(&thread1, & threadStack1, 1024, (void*)DL_StateMachine_ModeHandler, NULL, NULL, NULL, 7, 0, K_NO_WAIT); k_thread_create(&thread2, & threadStack2, 1024, (void*)DL_StateMachine_MsgHandler, NULL, NULL, NULL, 7, 0, K_NO_WAIT);
it compiles but then when I am trying to execute it I have the following issue:
Does anyone know how to correctly use the k_thread_create? My other question is, what’s k_thread_stack_t and what to do with it?
Thank you,

Hi All,
I have been working on RPL node example(which is in zephyr/samples/net/rpl_node), to work it as both central and peripheral concurrently. I have successfully integrated peripheral code with RPL node example, and device has been able to Advertise and able to establish the connection also. To act as peripheral, i have edited "prj.conf" file and has been working as peripheral. If i do same thing for central, device was not getting enter into scan mode. my aim is, each device should act as peripheral and central and on top of BLE links will send IPV6 packets by using RPL protocol. could you please help me to integrate Central(nrf52832 DK) with RPL_node?
