I would like to access a SPI Device (Ethercat Shield) over the Arduino Headers (SPI4). What do i have to do to get the /dev/spidev... device file in Linux ? Sorry, but i'm still confused what is enabled, what do i have to enable in DTS files and when...

How long does it take (approx) to rise or lower a GPIO pin fix configured to the M4 in the STM32MP157c, after issuing the command in the M4 code ? On our native STM32F409 board it takes around 10ns. I'm afraid the STM32MP1xx is much slower right ? Re...

Ok, what you used is the so called "Broadcast" Address :) Never use that for a connection. Tip, catch your preferred browser, go to the WWW and look for some basic tutorial around TCP/IP, Example: https://stevessmarthomeguide.com/basic-networking-cou...

Don't search for a sshd, you have "dropbear" installed as your ssh server. Do you find that:root@stm32mp1:~# ps -ef | grep dropbearroot 710 1 1 18:17 ? 00:00:00 /usr/sbin/dropbear -i -r /etc/dropbear/dropbear_rsa_host_key -BAnd with netstat y...

I have two DK2 here on my desk and are working well with SSH right out of the box.You don't have to install anything on the DK2 in terms of SSH. And by the way, you can't. These are so called YOCTO based Linux boxes. That means they are flashed with ...

Hi OliverOk thanks that sounds good. No i didn't measure anything on the MP1 Board, but i've made some bad experiences with other boards (i.MX7dual) where the GPIOs are quite slow (150 - 200ns) to raise or lower. So it should be enough to lock my GPI...
