Periodic k_timer's do not work in fractional ticks, no. If you schedule a 1000ms timeout it will be rounded up internally to exactly 33 hardware cycles, and that process will repeat each cycle. So

Hi, I understand that there are some problems because of 32768Hz RTC (I am now using NRF52-DK and want to use NRF52832 in my new HW) as referenced here:

Hi, I understand that there are some problems because of 32768Hz RTC with NRF52832 as referenced here: https://github.com/zephyrproject-rtos/zephyr/issues/9904 , there are some already merged PRs

Instead of adding k_usleep(30), I changed the SPI clock from 210kHz to 406kHz for STM32F769. Then, the problems of A and B are gone. Still I have the problem of C. I receive 0x07 instead of

From what I checked: - A. 74 clocks stop with a change in CS without sufficient delay - B. CMD0 (0x40 0x00 0x00 0x00 0x00 0x94) fails to send 0x40... (instead send 0x20...) - C. CMD0 fails to receive

Dear Marti Thank you very much for your reply. I can understand the difference now. Best regards Yasuhiko Okada

Hi, I should probably start by saying that I’m brand new to Zephyr and that I’m pretty sure I’m missing something obvious or just overlooked parts of the (great!) documentation. I’m trying to

Hi there In my application I try to use NVS on an external SPI flash (M25P16) which has an erase page size of 64k. As I realised, NVS seems to have some limit on its maximum sector size of just below

Dear Yannis (I have sent private reply, but for other people, I send this reply again). Thank you very much. I added the description for &spi2 in an overlay file. It worked. I appreciate it.

Hi, You don't need to add it. It exists in dts/arm/st/l4/stm32l471.dtsi To enable it just add the following in nucleo_l476rg.dts or an overlay file: &spi2 { status = "okay"; }; Yannis

Good day, I have decided to dive head first into Zephyr with a project of mine. I have a LIS2DH and a W25Q128JV Flash on the same SPI bus, with two GPIOs to control the chip selects. I have a
