How to use BOARD_ROOT to define out-of-tree boards?
Li, Jun R <jun.r.li@...>
Hi, I’m trying to use the new feature implemented by PR #6150 to define my private boards. I just copied samples/hello_word to an out-of-tree directory and copied boards/arm/stm32f4_disco to the directory hello_world to have a try. So, my directory structure is like this: . ├── boards │ └── arm │ └── stm32f4_disco │ ├── board.cmake │ ├── board.h │ ├── CMakeLists.txt │ ├── doc │ │ ├── img │ │ │ └── en.stm32f4_discovery.jpg │ │ └── stm32f4_disco.rst │ ├── Kconfig.board │ ├── Kconfig.defconfig │ ├── pinmux.c │ ├── stm32f4_disco_defconfig │ ├── stm32f4_disco.dts │ ├── stm32f4_disco.yaml │ └── support │ └── openocd.cfg ├── build │ ├── CMakeCache.txt │ └── CMakeFiles │ └── cmake.check_cache ├── CMakeLists.txt ├── prj.conf ├── prj_single.conf ├── README.rst ├── sample.yaml └── src └── main.c
However, I couldn't make cmake to find the board I defined by either of the following two ways: 1. Directly specify the BOARD_ROOT by the command: “cmake -DBOARD=stm32f4_disco -DBOARD_ROOT=./ ..”
2. Specify the BOARD_ROOT in my CMakefile: include($ENV{ZEPHYR_BASE}/cmake/app/boilerplate.cmake NO_POLICY_SCOPE) project(NONE)
set(BOARD_ROOT ./) target_sources(app PRIVATE src/main.c)
For the first way, I got an error: -- Selected BOARD stm32f4_disoc No board named 'stm32f4_disoc' found
For the second way, it can compile and find the board, but the used board directory is still the original one in Zephyr: -- Found PythonInterp: /usr/bin/python3 (found suitable version "3.5.2", minimum required is "3.4") -- Selected BOARD stm32f4_disco Zephyr version: 1.11.99 Parsing Kconfig tree in /home /projects/my_base_1.11/zephyr/Kconfig Using /home/projects/my_base_1.11/zephyr/boards/arm/stm32f4_disco/stm32f4_disco_defconfig as base
I’m wondering what’s wrong on my usage of BOARD_ROOT? Thanks for help!

Bluetooth BLE device not get discount
Vikrant More <vikrant8051@...>
Hello, Currently I am working on Zephyr Bluetooth APIs to build normal Services-Characteristics based BLE device. I've observed following things: 1) sometimes when app (for eg. nRF Connect) closes even after that device doesn't get disconnected 2) sometimes even smartphone Bluetooth switched off then also device doesn't go from connect state to disconnect state. Success ratio is approx. 60-70% Since device doesn't go in disconnected mode, it stop advertising & I have to restart it for reconnection. Is it because of App or smartphone OS not actually disconnecting at background level ? Thank You !!

Re: [Zephyr-devel] error while opening file (NFFS)
Pallala, Ramakrishna <ramakrishna.pallala@...>
Hi Vikranth,
The main change is the introduction of mount point which will allow us to have multiple file systems at once. Now the file system mounting responsibility to given to application and it should tie the backend storage which is intended to use.
We have three examples as of today which demonstrate the usage of file systems API’s:
tests/subsys/fs/fat_fs_api/ => Demonstrate FATFS usage, I would suggest you look into it as it is simple and not many files are there. tests/subsys/fs/nffs_fs_api/ => Demonstrate NFFS usage tests/subsys/fs/multi-fs/ => Demonstrate both FATFS and NFFS usage together.
Look into the test_*_mount.c files in these tests which will show how to mount a file system from Application.
This feature is destined for v1.12 release and I will add the documentation accordingly.
Thanks, Ram

I'm not able to understand it. Why Zephyr did these type of changes when there is no demo examples for modules like NFFS ? Please help to solve this issue. In tests/subsys/fs/nffs_fs_api/ there are multiple files ....which one to refer ?? What is proper sequence for initialization ? Please give me sample code to open, read, write & close for file using NFFS as per latest patches.

Re: [STM32L4] looks there is no way to flash and debug?

Ok, so openoncd support is indeed not provided for this board. And it happens it is not present neither in openocd. Though, it will work by re-using configuration provided for nucleo_l476rg. Duplicate following files and move them into nucleo_l432kc folder: -support/openocd.org -board.cmake

Hi Carles, There is no particular limitation on STM32L4 that should prevent you to flash and debug. Can you provide us more details on your set up to understand what is going on (board, SW, environment, error you encounter..)? Cheers Erwan

Hi Vikranth,
Zephyr VFS patches got merged yesterday. These changes are not part of v1.11 but got merged yesterday.
Please refer to the changes needed to comply with VFS under tests/subsys/fs/nffs_fs_api/ on the latest code.
Thanks, Ram

about to use FOTA & Lightweight flash storage layer for constrained devices from v1.11.0
Vikrant More <vikrant8051@...>
Hello, How to upgrade firmware on #nRF52840_PDK over Bluetooth Link using newly added FOTA feature in v1.11.0 ? Please provide in detail step wise solution if possible.Is it "$zephyr_base/samples/drivers/soc_flash_nrf5" ? If we try to update value of variable stored on flash, then we have to erase complete page or driver should write down new value on new address location. Is newly added flash storage layer take care of that since in general SoC supports only 10K erase cycle ? Thank You !!

Re: increasing nRF52 Bluetooth range

Hi Vikrant,
As I said before: «Feel free to supply the correct h/w Tx Power enumeration to callers of https://github.com/zephyrproject-rtos/zephyr/blob/master/subsys/bluetooth/controller/hal/nrf5/radio/radio.c#L112”
Please review the callers of “radio_tx_power_set”
One for sure is https://github.com/zephyrproject-rtos/zephyr/blob/master/subsys/bluetooth/controller/ll_sw/ctrl.c#L5902
Supply 0x08 instead of 0 as the current param.

Re: increasing nRF52 Bluetooth range
Chettimada, Vinayak Kariappa
Hi Vikrant,
The Zephyr BLE controller does not implement the Tx power set interface in the upstream code, hence Zephyr controller operates with +0dBm transmit power. Feel free to supply the correct h/w Tx Power enumeration to callers of https://github.com/zephyrproject-rtos/zephyr/blob/master/subsys/bluetooth/controller/hal/nrf5/radio/radio.c#L112
nRF52840 supports +8dBm and Zephyr controller supports external power amplifiers too using the PA/LNA GPIO lines, in case you want your h/w design to have external chips to get further tx power.
