Test-related labels on GitHub
Carles Cufi
Hi all,
I have tried to clean up the test-related labels on GitHub, performing the following changes: - "Testing" has been removed - "Testing Suite" has been renamed to "Test Framework" and should be used for issues that are related to either the framework or missing platforms (eg. a new target on QEMU, an issue that affects multiple individual tests) - "Tests" should be used for issues related to specific tests - "Sanitycheck" should be used for issues related to the sanitycheck Python script Additional labels, such as "Bug" or the relevant architecture(s) should be used to complement the information provided by the Test-related ones. I have tried to go through all test-related issues and re-label them as appropriate. Please use the new labels as described. Thanks, Carles

Carles Cufi
Hi all,
This is just a reminder that the feature merge window close is on the 8th of May. This means that any changes that are not bugfixes or documentation changes must be merged by then. See the full timeline for the 2.3 release here: https://github.com/zephyrproject-rtos/zephyr/wiki/Program-Management#actual-and-planned-milestone-dates Thanks, Carles

Connect two Zephyr instances via zeth interface
Lei Xu <lei.xu@...>
Hi, I'm implementing two zephyr projects in the same host, which will communicate with each other. Then I found the sample code https://docs.zephyrproject.org/latest/samples/net/eth_native_posix/README.html, which shows how to setup two zephyr instances that can communicate via the created zeth interfaces. I have tried exactly what the instruction writes, but it doesn't work when I tried to ping the device in the net-shell. So, could you give me some tips, should I configure anything else in my host? Or may be some necessaries that are missed in the instruction? Also, as an alternative method, I tried to run Looking forward for your reply. Thank you!
Kind regards, Lei

To fix this issue I only had to add CONFIG_LIB_CPLUSPLUS=y to my prj.conf file. Thanks pabigot ! Leo

std::map where type of key is struct

Hello all,
I am trying to create an std::map where type of key is struct and I provide my own comparator. The code compiles/executes correctly with g++ (click on links below) outside of the Zephyr environment but fails otherwise. Am I missing some CONFIG_ statements in prj.conf? How do I fix this issue?

you are running out of RX network buffers. Try to increase the value of CONFIG_NET_BUF_RX_COUNT and optionally CONFIG_NET_PKT_RX_COUNT options. Cheers, Jukka

Hi all,
I have cancelled the API meeting today due to my lack of availability today. To my knowledge, we did not have any pressing matters to discuss, but as always please let me know or add the issue or PR to the API review/cleanup/rework GitHub project in order to be discussed next week. Apologies for the short notice. Regards, Carles

Hi,
I'm implementing mqtt on an nucleo stm32 board (stm32f767zi). The communication from the broker seemed to work OK at first, however when stressing the communication a bit the next error appears multiple times in the log: ==> "<err> eth_stm32_hal: Failed to obtain RX buffer". What can be the cause of this? Kind regards Erik Samyn

Hello, I am new to Zephyr. I have a need to write code that runs on both RTOS and linux. It is structured as an event loop that can monitor sockets, local queues and timers for Linux. When looking at the APIs in the RTOS I noticed that there is no common poll API. Isee k_poll() can poll kernel objects while zsock_poll() can poll sockets. Is there a way to monitor sockets and kernel objects using the same event loop?Mostly for the same sorts of reasons that poll() in Linux can't wait on a POSIX condition variable or futex. The zsock_poll() implementation is designed to work the way it works on existing Berkley sockets code, and it understands sockets in the network layer. The kernel k_poll() abstraction understands existing kernel objects, which aren't sockets. That said, it wouldn't be impossible to make these interoperate. The k_poll_event object has a "signal" type which allows arbitrary external code to provide wakeup notifications to threads blocked in k_poll(). Someone could write a constructor for such a k_poll_event in the network layer without too much trouble, I think. It's possible we could remove the zsock_poll() implementation entirely and replace it with this sort of wrapper around k_poll, actually. But I haven't looked at that implementation and don't know what would be involved or what the costs might be. Andy

Build size of bluetooth and ip stack
#bluetooth
#nrf51822
mdl.mailme@...
Hi,
i am trying to build the bluetooth/ipsp/ example for the nrf51, but the build fails because the SRAM overflows (50kB usage with 32kB available on the nRF51). Also, the Flash usage is 98%. I checked the zephyr_prebuilt.map file to see the sizes of the single modules/libraries. It shows that only the bluetooth and ip modules use around 180kB of Flash and 32kB of SRAM. Is it normal for it to be this large? If yes, is there a possibility of reducing the size of those modules? I attached the zephyr_prebuilt.map file, the output of my self built parser showing the ROM and RAM usage of the single modules and the build output. Kind regards, Marco Liess

getting started with ssd1306 shield
Trevor Clarke
I'm new to zephyr and I'm trying to get a 128x32 SSD1306 display working with a stm32 black pill and I'm having trouble. My prj.conf has CONFIG_DISPLAY=y My CMakeLists.txt has set(SHIELD ssd1306_128x32) before the boilerplate include. When configuring I get a "Label or path arduino_i2c not found" so I tried adding "arduino_i2c=&i2c1" to my app overlay file and that didn't help. Am I missing something in my app code? Or do I need to modify the shield code to accommodate stm32? If so, where would I get started with that? Trevor R.H.

MCP2515 Interrupt
#can
turboaffe@...
Hello everybody, this is my first post.
I have a problem with the drivers/can/can_mcp2515.c interrupt configuration/the mcp2515 driver implementation. I would like to send a can message with the can_send function. On my board, a stm32 is connected to the mcp2515. The message is sent, i see it on the bus via candump, and my logic analyzer shows a falling edge on the mcp2515 interrupt output as soon as the mcp2515 is done with sending. The OS does not react on that falling edge, and my program is stuck on the blocking can_send function. I discovered that the whole thing works if i change the interrupt edge configuration/gpio flags as follows in can_mcp2515.c, lines 860 to 862: From:
if (gpio_pin_interrupt_configure(dev_data->int_gpio, dev_cfg->int_pin,
GPIO_INT_EDGE_TO_ACTIVE)) {
return -EINVAL;
}
To:
if (gpio_pin_interrupt_configure(dev_data->int_gpio, dev_cfg->int_pin,
GPIO_INT_EDGE_TO_INACTIVE)) {
return -EINVAL;
}
Can somebody point me to somebody who I could discuss this problem with? I am not sure if this is a bug or how it can work on the other boards, like the DF Robot CAN Shield one. Thank you!
