Dear All,
Thank you very much for your response. That problem is resolved by following your advised step. Moreover, now i was moving towards the HelloWorld example i received the following error.

This is most likely what Marti said, you need to add ~/.local/bin to your PATH:

If that works, you can make this change permanent via ~/.bashrc

MCUMGR SMP implementations
Rodrigo Peixoto <rodrigopex@...>
Hi all. My company is developing two boards let's call them Board A and Board B for illustrating purpose. Board A is simple it has some sensors and it has a shell interface for communicating with the other one. Board B is the "gateway" and has Internet connectivity through the Cellular network. They had to be created separately. We need to upgrade the firmware of both boards in the field. For now, Zephyr only supports FOTA over Bluetooth and Shell/UART, right? So I guess we'll need: 1 - to create a Shell SMP Client at Board B that will be able to upgrade the firmware of Board A using a version of the firmware received by the internet; 2 - to implement a different SMP Server at Board B to receive its own firmware by the Internet as well. Do you have any start point, tips, something that could help here? The future plan, after I made customs SMP Client and Server, is creating an SMP Server over Bluetooth Mesh. In another project, we will need that. Is anybody working with it already? Thank you.

henry.wagner@...
After implementing a throughput test for BLE using #nrf52840 hardware and Zephyr 1.14-rc1, notice some curious behavior in data we are collecting. The test seems to show that sending data from the central (client) to peripheral (server) throughput performance is relatively balanced per connection but one peripheral seems to get little data and one peripheral get more. In data flow from the peripherals to the central, it is much more unbalanced with one or two peripherals having all the throughput and the others having none.
The central to peripheral is 1:N where the central is a single point source. The many peripherals to central is an N:1 with many sources. In my case N is 1 up to 5, but would like to be greater. The overall aggregate throughput is constant, just not evenly distributed among the BLE devices or comm directions. Using DLE and 2M PHY Any thoughts to why this behavior is present and how to diagnose/resolve to produce consistent and balanced throughput among the BLE devices? Do I have something misconfigured in my devices? Can share if that will help.

Re: Syntax in dts file for defining a GPIO output based on nxp,kinetis-gpio.yaml
#defines
Bo.Kragelund@...
Thank you for your quick assistance yesterday Andrei.
Maybe I misunderstood your last point, but as I see it, it is the name "test_pin" in my example, which needs to remain the same across dts files for other boards to keep the same generated macro name in the dts configurations. It is also the name "test_pin" that is added as a header comment in the auto generated file generated_dts_board.h as /* test_pin */ I think the name "_test" is just a name for the dts node itself and not used anywhere. Bonus info: Using a "_" in the begining of the dts node name "_test" actually puts the generated macro names in the top of the auto generated file generated_dts_board.h, which might be a help to distinguish between your own definitions and the definitions made in zephyr already. Probably because the dts nodes are generated in alphabetic order. Best regards, Bo

Hi all,
We have just tagged Zephyr 1.14.0-rc3. At this point ONLY PRs related to docs or related to a GitHub issue / bug will go in. If a PR fixes a bug it MUST have an associated GitHub issue. Our bug counts are looking pretty good for the release at this point: 6 - High [Goal 0] 26 - Medium [Goal 20] 57 - Low [Goal 50] The final release is tentatively scheduled for the 12th of April. The full release log can be found here: https://github.com/zephyrproject-rtos/zephyr/releases/tag/v1.14.0-rc3 Thanks to everybody who contributed to this release! Kumar

Re: Syntax in dts file for defining a GPIO output based on nxp,kinetis-gpio.yaml

Andrei Gansari
Hello,
Yes, my example was hardcoded in regard to port and pin number. Your example makes them configurable via dts, while code remains the same.
I only have to point another thing: the generated macros name will remain the same in other dts configurations if you keep the same name across dts (in the example: _test {} ).

We don't use alias because we want to see in the code, that the defines comes from dts.
gpio_pin_configure(wdt_device, DT_GPIO_OUT_TEST_PIN_GPIO_PIN, GPIO_DIR_OUT | DT_GPIO_OUT_TEST_PIN_GPIO_FLAGS); gpio_pin_write(wdt_device, DT_GPIO_OUT_TEST_PIN_GPIO_PIN, 1);
I guess this is a way to do it, if you want to keep your code independant of pin numbers etc.

Re: Syntax in dts file for defining a GPIO output based on nxp,kinetis-gpio.yaml
#defines
Bo.Kragelund@...
Hello Andrei,
And thank you very much for your quick answer. I really appriciate the quick link to where I can find the documentation and also the example you have provided. I am also aware of, that it will be in the code, that you configure the pin to be input or output. But what is not so great is, that we would very much like to define the port and pin number at the dts level for the specific boards, that we support. We want the code to be generic and not be changed, if a new board will use another pin for the same function. This is what zephyr has achieved by making the gpio-leds.yaml and then setup the leds in the board specific dts files. By doing this, along with using alias, you simply refer to the define LED0_GPIO_PIN in your code across all boards without knowing what pin it is and what port in the code, which we like. We have actually made our own gpio-xxx.yaml, which looks similar to gpio-leds.yaml and placed it in the same location as gpio-leds.yaml. Then we put the following lines in the dts file for the given board: _test {
compatible = "gpio-xxx";
test_pin {
gpios = <&gpiob 22 0>;
label = "My test pin";
};
};
This will create the following in the auto generated header file: /* test_pin */
#define DT_GPIO_OUT_TEST_PIN_GPIO_CONTROLLER "GPIO_1"
#define DT_GPIO_OUT_TEST_PIN_GPIO_FLAGS 0
#define DT_GPIO_OUT_TEST_PIN_GPIO_PIN 22
#define DT_GPIO_OUT_TEST_PIN_LABEL "My test pin"
The code will then have lines like this: wdt_device = device_get_binding(DT_GPIO_OUT_TEST_PIN_GPIO_CONTROLLER); gpio_pin_configure(wdt_device, DT_GPIO_OUT_TEST_PIN_GPIO_PIN, GPIO_DIR_OUT | DT_GPIO_OUT_TEST_PIN_GPIO_FLAGS);
gpio_pin_write(wdt_device, DT_GPIO_OUT_TEST_PIN_GPIO_PIN, 1);
Of course you have to write the dts lines with the exact same names in all dts files supporting this function. Best regards, Bo

Re: Syntax in dts file for defining a GPIO output based on nxp,kinetis-gpio.yaml
#defines
Andrei Gansari
Hello Bo,
We have a general help page for Device Tree: https://docs.zephyrproject.org/latest/guides/dts/index.html
In your particular case, you need to set port b pin 22 as output.
Device Tree: The purpose of DT is to describe the HW of the board (boot time @ Linux, compile time @ Zephyr). K64F’s DT file is found in: boards/arm/frdm_k64f/frdm_k64f.dts I expect this is what you are looking at. It also includes file dts/arm/nxp/nxp_k6x.dtsi where port b is set using nxp,kinetis-gpio.yaml. Dtsi file is a generic dts include file that describes the SoC (we may have another board with the same SoC on it). Add the following to frdm_k64f.dts to use gpiob from nxp_k6x.dtsi: &gpiob { status = "ok"; }; You can comment out/remove the following to remove he led configuration on the same pin: red_led: led_0 { gpios = <&gpiob 22 0>; label = "User LD1"; };
Code: You can’t configure a pin as in/out, using DT, we have board’s pinmux.c (in boards/arm/frdm_k64f) to do that. This is because GPIO should be dynamic during the application. pinmux_pin_set(portb, 22, PORT_PCR_MUX(kPORT_MuxAsGpio)); The code above sets pin as GPIO (for the led in the case above). Then set pin to output and send a signal: #include <gpio.h>
pinmux_pin_set(portb, 22, PORT_PCR_MUX(kPORT_MuxAsGpio));
struct device *gpiob = device_get_binding(DT_NXP_KINETIS_GPIO_GPIO_B_LABEL);
gpio_pin_configure(gpiob, 22, GPIO_DIR_OUT); gpio_pin_write(gpiob, 22, 0);
DT_NXP_KINETIS_GPIO_GPIO_B_LABEL can be found in files zephyr/include/generated/generated_dts_board*** (relative to build folder) this is the effect of setting portb in dts.

Hello developers! leds { compatible = "gpio-leds"; red_led: led_0 { gpios = <&gpiob 22 0>; label = "User LD1"; }; };
But in general, I believe the idea is to define GPIO in the dts file based on the
nxp,kinetis-gpio.yaml file created for this purpose, instead of the gpio-keys.yaml file. "#cells": - pin - flags
Since I am rather new in dts and yaml syntax, I hope someone can help me with the syntax for setting port b, pin 22, and no flags, based on the nxp,kinetis-gpio.yaml file...
