Hi,I would like to make my STM32MP157 communicate with a FPGA in spi. I need to make long transfer (2-3 Mb) spi to get data acquired by the FPGA. But when I use the "spi_sync_transfer" function in my driver, I get the following kernel message:#spi_st...
Hi All!! I am currently using openstlinux-5.10-dunfell-mp1-21-11-17 for EV1. My idea is upgrade kernel version to 5.15 and keep u-boot-2020.10 and tf-a-2.4. My problem is that only upgrading the kernel and dtb, the kernel crashes and doesn't show any...
I have a small project under GPL v2 license which will not necessarily be used on STM device (maybe, but most likely not). There is a "Design Tip (DT0085)" which have some reference source code and I want to use it in my project (esp. page 7). I ca...
In my device tree, we config 400KHz, but on scope we see only ~ 50Hz, and the clock seems weird. Anyone know why? &i2c1 { pinctrl-names = "default", "sleep"; pinctrl-0 = <&i2c1_pins_a>; pinctrl-1 = <&i2c1_sleep_pins_a>; i2c-scl-rising-time-ns = <185>...
Hello,when configuring a binary semaphore with CubeIDE the parameter initial_count defaults to 1. Is there a way to tell CubeIDE to always initialize this with value 0 for my projects?regardsHerbert
Hello!I'm new at ST!I'm looking to rebuild a project I built on a SBC (rpi4), but now in a board for commercial use and mass production, as for now I bought nucleo64 - F401 for testing.The project consist on connecting a webcam, displaying photos o...
Is stated on STM32MP157 datasheet's boot mode table that the MPU can be booted through UART: – USART2/3/6 and UART4/5/7/8 on default pins Nevertheless, I wasn't able to find which are the default pins for the UART interfaces, on the datasheet or refe...
I am trying to achieve hard real-time under 100us on the STM32MP157f-eval, specifically, on the Cortex A7 dual core.Note: I specifically target the Cortex A7 cores because the M4 is already taken for other tasks which requires much smaller latency.Wh...
Hello,I am currently working with st-image-core in Yocto and attempting to remove some packages that are not necessary for our needs. While I have successfully removed a few packages, some functionality on our board has stopped working because I may ...
I've got the STM32MP135F-DK Discovery kit yesterday; and am going stuck on setting up and using the contributed microSD. Demonstartions are not starting.My Steps so far:- STLink software is installed (WIndows10 pro). - the supplied microSD ist instal...
