Hi Kai,

I don’t think that sample exists: samples/microbit/generic_onoff_svr.

Maybe you have updated your Zephyr tree and that sample has been moved or renamed? Unless of course this is your own sample that is not part of Zephyr.

Furthermore, please follow the instructions in this email to switch to the new naming conventions for GNU Arm Embedded:

https://lists.zephyrproject.org/g/users/topic/gcc_arm_embedded_is_now_gnu/24238396

I just tested building the hello_world  and bluetooth/mesh_demo samples for bbc_microbit on Windows 10 with the latest master had no issues.

Hi guys,

    The default baudrate of zephyr hci_uart sample on nordic 52832 is 1Mbits. I'd like to configure it to 115200. Is there anyone who knows how to configure it in defconfig dts or some config file else ?

   Thanks! 

Hi, 

How can I update my local zephyr project (that I have cloned from Github before) to the latest (or a defined) version?

Regards,
Mina

I have filed an issue related to HCI UART sample from zephyr running on nrf52832. I compiled the hci_uart sample successfully, but I am not able to use the UART interface through an external USB-UART converter (CP2102 ). I btattach the dev/ttyUSBx and monitor the communication with btmon on the linux host,It indicates that the 52832 chip running hci_uart sample does not respond to the Linux host who sends hci reset command to it.Is anyone met this problem before ？ Any device on debugging and resolving this problem will be highly appreciated,thanks. 

Hi Jiri,

Welcome to awesome zephyr community.

Hi,
Im new to Zephyr and Im trying to measure the GPIO handler latency. I have modified the samples/basic/button example to toggle LED pin when the handler rises. The test is to measure the time between input pin change and output pin change. I have measured maximal value about 3us and typical about 2.6us. The processor is SAME70 @ 300MHz so 3us is 900 instructions - why it took so long? It should be in tenth of ns.  Do I have correct approach or am I doing something wrong?  I have checked the sensor drivers and they are using the same workflow. 
 

The handler code is 

void button_pressed(struct device *gpiob, struct gpio_callback *cb, u32_t pins) 
{
   gpio_pin_write(dev, LED, cnt % 2);
   cnt++;
   printk("Button pressed at %d\n", k_cycle_get_32()); 

k_cycle_get_32() prints cycles.

Use k_uptime_get(). Follow this to measure time : http://docs.zephyrproject.org/kernel/timing/clocks.html

Jiri Kubias
