Hey there, I am new to STM32MP1 and this forum has been a great help. During the last week I am trying to understand the OpenAMP between the M4 and A7. The ttyRPMSG makes things quite straight forward for the M4 part. When going to the linux part, us...
I create a process A to communicate with M4, another process B every 2 min will be calculate some data cost 230ms. in this inteval, process A cant use OpenAmp to send cmd to M4, until process B complete the calculation.
Hi,I tired to refer to "https://wiki.st.com/stm32mpu/wiki/How_to_integrate_AWS_IoT_Greengrass_on_top_of_openSTLinux_distribution" to do "bitbake st-image-demo-aws"My compiled OS is UBUNTU 20.04.I got below error:"ERROR: ParseError at /home/zouqz/stm...
Hello,we want to bring up our own board with stm32mp157c. Processor is connected to a Microchip LAN8720 through RMII.I configured device tree as described here:https://wiki.st.com/stm32mpu/wiki/Ethernet_device_tree_configuration#RMII_with_Crystal_on_...

For one project we would want to use only de M4 core of the SM32MP157 MPU. We want this because we have no time to learn how to develop the whole application using linux and the whole potential of the MPU, but we would want to have the hardware ready...
If I order from st, how many days does it usually take to get to Korea?I placed an order last week... it's only for processing.
Hey.. Hi.. hello..Hope you all are doing wellI've my custom made board, which is quite similar with the STM32MP157 DK2 board Unfortunately, it's unable to bootDTS configuration for the PMIC, Clock and UART seems good I need to starts with the SPL/U-b...
Hi,iam trying to get a full understanding of remoteproc and its resource tabel. In the paper i read i understood it that the resource table is used to give the information about the vrings location to the master and the slave. The master parses the ...
