scripts/subfolder_list.py: os.symlink: OSError: [Errno 36] File name too long
Abhishek Shah
Hi - I am facing an issue where os.symlink call in subfolder_list.py(zephyr v2.2) results in below error: "scripts/subfolder_list.py", line 56, in main os.symlink(directory, symlink) OSError: [Errno 36] File name too long Here is the example of one of the symlink getting created on one of the systems: directory path: '/tmp/yocto_builds/

I can think of 2 ways to reduce symlink length: 1. Symlink creation should use relative path instead of absolute path. As symlink is in zephyr build directory and original directory is in build directory; a relation needs to be established in between zephyr source directory and build directory. 2. The final symlink name should not use entire PATH in the name, rather just start from "include_*" For example: Instead of this: _tmp_yocto_builds_20133855_genericx86-64_poky_build_tmp_work_aarch64-poky-linux_brcm-zephyr_gitAUTOINC+a20a30cd86_bfa48a337e_dbbf7c9b30_f3635d87f4_90d93a11ba_ae871b61ae_5ba575618e-r0_git_zephyr_include_arch_arm_aarch32_cortex_m_mpu Name could be just: include_arch_arm_aarch32_cortex_m_mpu This should reduce symlink length almost by half.

Hi Community,
I have one custom board on which I'm having Nordic's nrf52840_pca10056 chip on which i have flashed zephyr's 'hci_uart' sample application for the beacon scanning purpose. "hci_uart" app is build with hardware flow control enable (Tx, Rx, RTS, CTS). I'm using below commands to create the hci interface. 1) btattach -B /dev/ttymxc0 -S 1000000 2) hciconfig hci0 up root@board-imx6ull:~# hciconfig
hci0: Type: Primary Bus: UART
BD Address: 00:00:00:00:00:00 ACL MTU: 27:7 SCO MTU: 0:0
UP RUNNING
RX bytes:504 acl:0 sco:0 events:38 errors:0
TX bytes:278 acl:0 sco:0 commands:38 errors:0
--> Here, hci interface is now UP RUNNING you can see above. Now, when i use "hcitool lescan --duplicates" command to scan the beacons, it starts scanning immediately but after 3-4 minutes it stops scanning, even though all the beacons in surrounding are still present and advertising. Tried without '--duplicate' switch but same issue is there. Q1: Is there any issue in zephyr's hci_uart application or what? NOTE : My actual use case is to scan the BLE beacons continuously. Thanks, Mayank

Mayank <mayank7117@...>
Hello All,
I have one question regarding the ability of zephyr's hci_uart sample app. I am using this application on nrf52840_pca10056 for scanning the ble beacons. Scenario is i can see "hci0" interface UP RUNNING. and my custom application starts scanning beacons continuously (Here I'm using bluez's api). Here, as i am in continuous scanning/receiving mode, I can see that when I'm using "hciconfig" command to show hci interface, there Rx bytes keep on increasing. $hciconfig hci0: Type: Primary Bus: UART
BD Address: 00:00:00:00:00:00 ACL MTU: 27:7 SCO MTU: 0:0
UP RUNNING
RX bytes:247820 acl:0 sco:0 events:1643 errors:0
TX bytes:295 acl:0 sco:0 commands:40 errors:0
--> Now, After few times (5-10 minutes) Rx bytes count becomes so high and may be because of that the beacon scanning stops entirely. Is there any limitation of beacon scanning? (I want more no of samples per second of ble beacon and thats why i'm using hci0 interface for continuous scanning). NOTE: After scanning for every 10 seconds, I'm able to flush the UART buffer successfuly. Thanks, Mayank

HWINFO API clarification
Steven Slupsky <sslupsky@...>
There were two recent issues (#23444, #24103) that identified a byte ordering issue with the hwinfo API. A PR (#24203) has been submitted to clarify the hwinfo API identifier data structure. This clarification has resulted in changes to the sam0 and nordic drivers. Moreover, some components that depend on the hwinfo api may have implemented work arounds for this issue. Issue #24103 identified the USB identifier was affected and issue #23444 identified Bluetooth may be affected. A summary of the commit is provided below. Please note other drivers may be affected by this issue. The identifier data structure for hwinfo drivers is clarified. Drivers are responsible for ensuring that the identifier data structure is a sequence of bytes. The returned ID value is not supposed to be interpreted based on vendor-specific assumptions of byte order and should express the identifier as a raw byte sequence. The changes have an impact on users that use the hwinfo API to identify their devices. The sam0 driver byte swaps each 32 bit word of the 128 bit identifier to big endian. The nordic driver byte swaps the entire 64 bit word to big endian.

How to contribute code to hal_nxp of zephyr
FrankLi
Hi,
I found the following problem in hal nxp spi, and there is a corresponding solution, how should I submit these codes to hal_nxp, it seems that zephyr hal_nxp does not accpet the modiftion of the driver code. Issue 1: LPSPI_MasterSetDelayTimes nt32_t realDelay is used, subsequent calculations may cause realDelay to overflow and produce incorrect delay data Issue 2: LPSPI_MasterTransferComplete did not clear kLPSPI_TransferCompleteFlag, the other interrupts that followed may be treated as Transfer Complete, resulting in an abnormal reception status of zephyr spi

Dev-Review Meeting Agenda Apr 9
Kumar Gala
Here’s the agenda topics for this week:
* Review PR’s tagged with dev-review * Use of DTS Alias v Chosen for device selection: We have a number of DT_ defines like: DT_ADC_{0..n}_NAME DT_RTC_{0..n}_NAME DT_ENTROPY_NAME DT_I2C_{0..n}_NAME DT_FLASH_DEV_NAME Do we replace these with chosen properties: zephyr,adc-{0..n} zephyr,rtc-{0..n} zephyr,entropy zephyr,i2c-{0..n} zephyr,display /* new */ * zephyr,flash meaning and usage / DT_FLASH_DEV_NAME and flash controller. - look at deprecating zephyr,flash (which was mostly a means to get CONFIG_FLASH_BASE_ADDR/SIZE vals). Replace with zephyr,flash-ctrl which would get us DT_FLASH_DEV_NAME. * DT SAM Atmel Pinmux / NXP pinmux https://github.com/zephyrproject-rtos/zephyr/pull/24164 https://github.com/zephyrproject-rtos/zephyr/pull/20398/files * Any topics anyone else has - k

Zephyr networking testing in LAVA, was: Re: Network forum agenda
Paul Sokolovsky
Hello,
On Mon, 6 Apr 2020 21:44:27 +0300 "Paul Sokolovsky via lists.zephyrproject.org" <paul.sokolovsky=linaro.org@lists.zephyrproject.org> wrote: [] If there is time, I'd like to share some progress on setting up CII appreciate being able to present my work quickly and the discussion of testing matters which followed. As it was just a quick spoken presentation, I'd like to share a few links showing more details, with the idea to keep wider community in loop of testing efforts around Zephyr. So, in this work Linaro LITE team uses the LAVA system (Linaro Automation and Validation Architecture), which is an open source project at https://www.lavasoftware.org/ (we run a particular deployment at https://lite.validation.linaro.org/). How it works is that we build Zephyr tests/samples in Jenkins (using the standard Zephyr "sanitycheck" tool), then submit binaries to LAVA, accompanied by a "test job definition", which is a YAML file like https://lite.validation.linaro.org/scheduler/job/960800/multinode_definition#defline1 . The job is then being run, with log of interaction recorded and analyzed for success/failure. In this case it's a networking test which involves 2 "nodes": a DUT (device under test) per se (FRDM-K64F board): https://lite.validation.linaro.org/scheduler/job/960800.0 and a docker container representing "a host": https://lite.validation.linaro.org/scheduler/job/960800.1#L56 . Here, the actual test interaction happens on the host, which starts with easy-pinging a device, then pings more with full Ethernet frames, then does a "poorman's flood ping" of pinging 1000 times with full packets and 10ms interval. All these actions are encoded in the YAML definition and are easily reconfigurable. LAVA checks that individual actions outcome satisfies success criteria and records overall results, e.g. https://lite.validation.linaro.org/results/960801/0_ping . The biggest value of such a system would come from early notifications of failures, and ability to compare results over time. The best ways to achieve that is so far under investigation (the whole work is largely a prototype at this stage). As discussed yesterday, we all by now should be aware that "Zephyr testing" bastion is being stormed by multiple stakeholders in different ways, and I just wanted to share Linaro's approach and progress with wider community. While the primary drivers for this works are requirements of our members interested in Zephyr, who already adopted the LAVA system, the work itself is open-source, results are public, and hopefully useful for a wider Zephyr community. (And different teams working on testing definitely should reuse results of each other's work, and further the best practices for making Zephyr more testable and quality-assured).
