It adds a dependency between DL and offsets_h.

offsets_h is a target that happens to depend on various kernel headers, including syscall_list.h, which evidently was used by the application library.

I'm not aware of any such example.

Hi,

Thank you for your reply. It's working.

What does add_dependencies(DL offsets_h) do?

Is there any zephyr cmake example using multiple CMakeLists I can read?

Thanks for your help!

Subject: [Zephyr-devel] cmake application project architecture

Hi everyone,

I am currently working on the Zephyr OS with a FDRM_K64f board from NXP.

I want to create my own application using cmake as recommended by the documentation.

However I don't want to put everything in one CMakeLists.txt. I want to break down my project into libraries (multiple CMakeLists.txt).

Do you know if there is any documentation talking about that?

My top CMakeLists looks like that:

cmake_minimum_required(VERSION 3.8.2)

include($ENV{ZEPHYR_BASE}/cmake/app/boilerplate.cmake NO_POLICY_SCOPE)
project(NONE)


add_subdirectory(${CMAKE_CURRENT_SOURCE_DIR}/DataLinkLayer
${CMAKE_CURRENT_SOURCE_DIR}/build/${BOARD}/DataLinkLayer)

target_sources(app PRIVATE src/main.c)

target_link_libraries(app
PRIVATE DL
)


And my second CMakeLists (under the folder DataLinkLayer) looks like that:

include_directories(${CMAKE_CURRENT_SOURCE_DIR}/src)

add_library(DL src/DataLinkInterface.c)

target_include_directories(DL
INTERFACE ${CMAKE_CURRENT_SOURCE_DIR}/Interface)



The issue is I can include the boilerplate.cmake in only one CMakeLists.txt otherwise It's not working, But, the second CmakeLists doesn't know the zephyr library..

I tried to add: include_directories(/home/user/zephyr/include) in the second CMakeLists but it is not enough. Do you know what should I do?


Thank you,

Hi,
I am trying to use the i2c on my custom board. I can read data from the devices, but (oddly) I cannot write to any of the 3 devices "attached" to the i2c line. I am using SDA on pin P0.06 and SCL on pin P0.07. Any clue? I have already spent a lot of time trying to fix this and nothing seems to work in this direction. 

Zephyr version: 1.13

i2c configs:
prj file (begin)
...
CONFIG_I2C=y
CONFIG_I2C_NRFX=y
CONFIG_I2C_0_NRF_TWI=y
CONFIG_I2C_INIT_PRIORITY=60
CONFIG_SYS_LOG_I2C_LEVEL=4
CONFIG_I2C_0=y
...
prj file (end)

board.dts (begin)
...
&i2c0 {
status = "ok";
sda-pin = <6>;
scl-pin = <7>;
};
...
board.dts (end)

I am using the commands like: 
error = i2c_burst_read(i2c_dev, ACC_I2C_ADDR, reg, &temp, 1);
error = i2c_burst_read16(i2c_dev, ADE_I2C_ADDR, reg, &buf, 4);

error = i2c_burst_write(i2c_dev, ACC_I2C_ADDR, reg, &setup, 1);
error = i2c_burst_write16(i2c_dev, ADE_I2C_ADDR, reg, &buf, 3);

All the reading commands work and the writing ones do not show an error and seem to make no effect.  


Thank you.

Hi Akash,

Maybe have also a look at this example:

uart hardware flow control problem of nrf52_pca10040 #uart #nrf52832

icephyr
 

Hi guys,
     I met a problem here and hop anyone can help. Thanks.

     I enable hardware control in menuconfig, build a firmware of hci_uart sample and burn the firmware into nrf52_pca10040 (nrf52832), 
(top menu) → Device Drivers → Serial Drivers → nRF UART nrfx drivers
                                                                     Zephyr Kernel Configuration
[*] UART Port 0 Driver type (nRF UART 0)  --->
[*] Enable interrupt support on port 0
[ ] Enable parity bit
[*] Enable flow control
 
and then connect it  with my NXP board via uart, tx rx rts cts,
but when I attach the ble with command hciattach, it prints time out and seems the uart cannot communicate.
root~# hciattach /dev/ttymxc2 any 115200
Device setup complete
root:~# Bluetooth: hci0 command 0x1003 tx timeout
root:~# Bluetooth: hci0 command 0x1001 tx timeout
root:~# Bluetooth: hci0 command 0x1009 tx timeout
So I wonder if the hardware flow control works fine with nrf52832 or zephyr ? Or maybe my way to enable hardware flow control is wrong ?

By the way, is there any problems that we use software flow control instead of hardware flow control when  the baudrate of uart is 1M ?

Thanks if someone can give me any advice.


cmake application project architecture

Florian Fouillet <Florian.Fouillet@...>
 

Hi everyone,

 

I am currently working on the Zephyr OS with a FDRM_K64f board from NXP.

 

I want to create my own application using cmake as recommended by the documentation.

 

However I don’t want to put everything in one CMakeLists.txt. I want to break down my project into libraries (multiple CMakeLists.txt).

 

Do you know if there is any documentation talking about that?

 

My top CMakeLists looks like that:

 

cmake_minimum_required(VERSION 3.8.2)

 

include($ENV{ZEPHYR_BASE}/cmake/app/boilerplate.cmake NO_POLICY_SCOPE)

project(NONE)

 

 

add_subdirectory(${CMAKE_CURRENT_SOURCE_DIR}/DataLinkLayer

${CMAKE_CURRENT_SOURCE_DIR}/build/${BOARD}/DataLinkLayer)

 

target_sources(app PRIVATE src/main.c)

 

target_link_libraries(app

PRIVATE DL

)

 

 

And my second CMakeLists (under the folder DataLinkLayer) looks like that:

 

include_directories(${CMAKE_CURRENT_SOURCE_DIR}/src)

 

add_library(DL src/DataLinkInterface.c)

 

target_include_directories(DL

INTERFACE ${CMAKE_CURRENT_SOURCE_DIR}/Interface)

 

 

 

The issue is I can include the boilerplate.cmake in only one CMakeLists.txt otherwise It’s not working, But, the second CmakeLists doesn’t know the zephyr library..

 

I tried to add: include_directories(/home/user/zephyr/include) in the second CMakeLists but it is not enough. Do you know what should I do?

 

 

Thank you,

 


Re: Zephyr BLE Controller Nordic - BLE qualification process

Carles Cufi
 

Hi Frank,

 

Regarding licensing, I have no real information there, I would recommend you check with an expert.

Regarding qualification, yes, the link you sent is correct. Zephyr has a qualified controller and host, and BlueZ has several qualification as someone else pointed out.

 

Regards,

 

Carles

[Edited Message Follows]

Hi Carles,

Probably all is here for the qualification process, correct? : https://www.bluetooth.com/develop-with-bluetooth/qualification-listing

Just wondering do we have extra concerns should we rely on the BlueZ stack at Host side except for the GPL licensing.
Probably when relying on QT which is LGPL and wraps the BlueZ stack we don't have issues around strict GPL licensing?

Update 9h38 21/11/2018 :
Our company has a SIG account, so I have registered for a user account, to be able to fetch documentation and ask questions.

Ble mesh stack not compatilbe with c++ #ble #bluetoothmesh

robert.konc@...
 

Hi,

When could we expect that blemesh code will be usable in c++.
Most header files in zephyr are compatible with c++ but not ble mesh headers.
No #ifdef __cplusplus in headers.

Robert


Leds_demo on nrf52840 #nrf52832 #zephyrbluetoothmesh

Akash Naidu <akashnaiduece@...>
 

HI All,
Recently i have started working on Zephyr RTOS to explore IPV6 over BLE.And i am totally new this.
I would like to form a mesh network with PCA10059(5 boards) and PCA10040(1 boards) boards, and control the leds on boards.

Now, i have been successfully established connection with nordic board and PC and was getting proper response from device(If i ping from PC).
But i don't know how to control the LEDS.
I have seen a demo example in "net/leds_demo", with this can we make a mesh network and control the LEDS?
could you please help me to form a mesh network on IPV6 over BLE? if possible please suggest reference examples for nrf52 DK.
And i am total new to IPV6 over BLE to form mesh network, so please provide suitable explanation about IPV6 over BLE to form mesh network in Zephyr RTOS.    

Advance in thanks.

Akash.

Guys,
I’m looking to see if someone (or group) can help with maintenance of the Atmel SAMD2x SoC family. We have a few things that need updating (like the watchdog driver). And need someone I can check in w/from time to time if there are questions or we need testing on a board.
Let me know if you can help in the short term with converting drivers/watchdog/wdt_sam0.c to use the new watchdog API.
[ I also have a question about testing flash support ]
Hi,

Got buried in my inbox. Happy to help.

I'm currently winding down a project on the SAM21 - I was planning on looking at the USB.

I don't mind running some updates/tests/reviews as needed. Here to help, let me know what's required I can make time.
