Adding a costume module to my project
#west
Stefan Hristozov
Hi,
I want to add a module to my project. My folder structure looks like this: <top dir> |---modules | |---module1 | | |---CMakeLists.txt | | |---inc | | |---src | | |---zephyr | | |---module.yml | |---module2 |---app |---app1 Where modules/module1/CMakeLists.txt: zephyr_interface_library_named(test) target_include_directories(test INTERFACE inc) zephyr_library() zephyr_library_sources( src/test.c ) zephyr_library_link_libraries(test) target_link_libraries(test INTERFACE zephyr_interface) modules/module1/zephyr/module.yml: build: cmake: . app/app1/CMakeLists.txt: cmake_minimum_required(VERSION 3.13.1)
include($ENV{ZEPHYR_BASE}/cmake/app/boilerplate.cmake NO_POLICY_SCOPE)
project(NONE)
set($ENV{ZEPHYR_EXTRA_MODULES} pbs_path/module1)
FILE(GLOB app_sources src/*.c)
target_sources(app PRIVATE ${app_sources})
target_include_directories(app PRIVATE $ENV{ZEPHYR_BASE}/subsys/net/ip)
target_link_libraries(app PRIVATE test)
Unfortunately, with this set up module1 doesn't get compiled and I get a linker error when I try to use functions from that module. I assume that something goes wrong with ZEPHYR_EXTRA_MODULES but I don't know what. Best regards Stefan

Hello all,
I have been doing development with stm32f103 (blue-pill) board - and it has the system bootloader burned in. The bootloader uses settings 115200, 1 stop, even parity [1]. I would like to change my "normal" uart settings accordingly. I tried googling for device tree bindings, but it seems like there is no bindings for parity at device-tree level? If device tree has no support for parity - i guess it is OK to re-initialize the uart with proper settings in early "application" main() ? Long story: I have successfully flashed the device with UART_1 using stm32loader.py over wire and wireless. Now final aim is to do firmware upgrade with the system bootloader over bluetooth by connecting HC-05 to the serial port and enter the bootloader programatically (by writing certain value to backup-registers, and checking that value on early boot). It shall require (for simplicity) that "normal mode" and "bootloader mode" shall use same uart settings. I tested that flashing over bluetooth seems to work ( but is painfully slow ). [1] St / AN3155 Br, Pauli

Bluetooth peripheral - correct way of updating internal characteristic's value
Martin Kozusky
Hello,
I have defined characteristic, which can be read, it's user_data is pointing to buffer1. Now when I want to read the data by central, Characteristic Attribute read callback is called. In this callback, I can do something like in "samples/bluetooth/peripheral" static ssize_t read_vnd(struct bt_conn *conn, const struct bt_gatt_attr *attr, void *buf, u16_t len, u16_t offset) { const char *value = attr->user_data; return bt_gatt_attr_read(conn, attr, buf, len, offset, value, strlen(value)); } and just return the content of buffer1 itself (if I am correct and attr->user_data points to it) now the question is - I have a new content for buffer1 prepared in buffer2 and in procedure called from main(), I do memcpy(buffer1,buffer2,sizeof(buffer1)). Can it happen, that the memcpy instructions are interrupted by read callback, so that buffer1 is inconsistent and I should use some locking mechanism (which one?) or is memcpy safe operation and buffer1 should always be ok? Or is there any other suggested way of updating characteristic's value than just modifying the buffer1 directly? Thanks.

Hi Rob, You can set the following Kconfigs in your prj.conf:
CONFIG_CODE_ITCM=y CONFIG_DATA_DTCM=y
See soc/arm/nxp_imx/rt/Kconfig.soc for more details.

Re: Feedback requested on west manifest imports
Bolivar, Marti
Hello,
I've cut a new west pre-release today (0.6.99.dev5) which is feature complete for manifest imports. The main new feature since 0.6.99.dev4 is you can now use whitelists and blacklists to filter what projects you import, with a slight change of plan from the original proposal which is reflected in the documentation. We'd like to wrap up this west release in the next week or two, so if you have any more feedback, please let us know! This introductory file is still valid: https://github.com/mbolivar/my-zephyr-app/blob/master/README.rst The working documentation build is still here: https://builds.zephyrproject.org/zephyrproject-rtos/zephyr/20433/docs/guides/west/manifest.html#manifest-imports You may need to clear your browser cache and reload to get the latest build. Thanks, Marti

Sample app hello_world fails with z_arm_usage_fault in arm_core_mpu_enable when linked in RAM
robmcgurrin@...
Hi,
I am running on a nxp i.mx RT1064 eval, board mimxrt1064_evk. I created a custom linker file to link the app to SRAM. Here are the mods I made to the default linker file include/arch/arm/aarch32/cortex_m/scripts/linker.ld to force everything into SRAM: #ifdef CONFIG_XIP
#define ROMABLE_REGION SRAM
#define RAMABLE_REGION SRAM
#else
#define ROMABLE_REGION SRAM
#define RAMABLE_REGION SRAM
#endif
And then I added this to prj.confCONFIG_HAVE_CUSTOM_LINKER_SCRIPT=y
CONFIG_CUSTOM_LINKER_SCRIPT="foo_linker.ld" When I run the app I get this fault: z_arm_usage_fault () at arch/arm/core/aarch32/fault_s.S:92 Any suggestions? Is there a better way to link my app to RAM? Thanks in advance, Rob

Re: Windows hosted development
Carles Cufi
Hi Peter,
As you will have noticed in our Getting Started Guide for Windows (https://docs.zephyrproject.org/latest/getting_started/index.html), we only really propose two solutions:
So I really don’t think that the statement “Getting started guide has too many open ended solutions for windows host” is accurate.
Regarding your requirements:
Windows IDE-support of some kind, such as visual studio or eclipse, including both build and debug working out of the box.
Those are easily achieved using the default cmd.exe instructions and then either Eclipse or VS Code. In fact, the section describing Eclipse debugging assumes running on a Windows host: https://docs.zephyrproject.org/latest/application/index.html?highlight=eclipse#eclipse-debugging
If you’d like to contribute instructions on how to use VS Code instead, please do so as a pull request. A starting point for that might be: https://github.com/bus710/zephyr-rtos-development-in-linux Most of the instructions in that GitHub repo should apply to Windows.
Regards,
Carles

Hi
Are options for windows development documented somewhere. Getting started guide has too many open ended solutions for windows host I think.
There are so many alternatives such as Two separate physical boxes including everything. Turn chair to switch... Windows host with some remote desktop to physical machine. Windows host with some remote desktop to virtualmachine. Windows host with shared folders to virtualmachine and ssh. Windows host with linux subsystem Windows host with CMD (Possibly Linux host combinations as well but that is another topic...)
What is important to achieve is Windows IDE-support of some kind, such as visual studio or eclipse, including both build and debug working out of the box.
Riot has a convenient virtual machine (through vagrant) for builds and windows hosted debugging in eclipse supported through shared folders to vm. Maybe some inspiration from there?

UART DFU from nRF9160 to nRF52840
ljaynes87@...
I am looking to DFU an nrf52840 over UART from an nRF9160. The board is set up similar to the Thingy:91. The firmware will be downloaded over LTE on the 9160 and will need to be sent over to the 52840 via UART. Would be best place to start be the smp_svr sample? I know the sample instructions suggest using the mcumgr Command-Line Tool but I need to do this from the 9160. Does the smp_svr provide support for the 9160 to run the DFU commands and start an update on the 52840?

If you look closely you will see that there is no capability for user mode functions to install a callback handler. This type of operation is supervisor mode only.
In the callback handler the application has registered from supervisor mode (typically at application initialization), use an IPC object to wake up a user thread for further processing.
There’s some example code in samples/userspace/prod_consumer
This is something we’d like to iterate on further so if you can come up with some scenarios that you don’t think are well supported please file GH enhancement tickets and assign to me for further discussion.

Hi,
Could someone shed some light on ways in Zephyr for Kernel to signal, or send a message to, threads running in the userspace?
I see some examples using callback functions, but wonder if that is a good practice: it is generally a security risk to run a function provided by a userspace application in the supervisor mode.
Any thoughts/pointers/suggestions would be greatly appreciated.
Many thanks in advance and with kind regards,
