Hello, I am working on the stm32mp157-dk1. I would like to create a 32bits parallel bus on cortex A7, at a frequency greater than 20Mhz but when I do a test on a pin I get a max frequency of 120khz, which is too low. I think this is the wrong program...
Hi,iam a bit confused aboute the remoteproc framework and if my understanding of it is correct.In my view, the remoteproc framework can start the m3 firmware with having its elf-file in a dedicated place of the filesystem. The remoteproc also parses ...
Hy wanted to make a kernel Module and i wanted to know whats the best way to acces the uart from Kernel Space.So far i enabled the UART in the device try and now i am able to send data. But now i know since the uart us in userspace i cant access it f...

I have a question about the Starter Package.When I start STM32MP157x-EV1 (+en.FLASH-stm32mp1-openstlinux-5-4-dunfell-mp1-20-11-12), I get the following logroot@stm32mp1:~# dmesg | grep ether[ 1.642061] stm32-dwmac 5800a000.ethernet: PTP uses main c...
We have an virtual uart FreeRTOS application running on CM4, it captures SPI data and sends to A7 through virtual uart. Sometimes, the FreeRTOS application freezed, A7 can not read the data through /dev/ttyRPMSG0 again, at the same thime, Linux 5.4....
I'm trying to build the large buffer exchange example but have been unsuccessful so far. I have the distribution installed and have no problem building the default package but when I try to build with the logic analyzer I get repo failures and compi...
