Hi,iam trying to get an understanding of the OpenAMP Framework and i wanna use it for interprocess communication with the STM32MP1. As my understanding, the OpenAMP Framework could be used from Baremetal/RTOS side and apparently also from Linux Side....
Hello,we have a custom board based on STM32MP151C. On our SPI is the Ethernet Switch KSZ8794. How should I proceed to enable the ethernet in the U-Boot? I have already configured the etherne0 node (according to the ST documentation). Should I add the...
We are using the latest STM32CubeIDE (1.4.0) and are trying to develop applications for linux user space on our STM32MP157 board. Our goal is to use the cross compiler toolchain for developing and debugging with the IDE.When we create a new project, ...
I am interested in the platform to evaluate wifi chips from different vendors. But based on the quick run through schematic, I don't think its possible to connect any different wifi chip (which has sdio as supported interface) in the DK2 kit. If anyo...
We have confirmed the operation on our original board that "STM32MP151CAA3" mounted on.When I start our Cortex-A7 (Linux) FW and try to load our Cortex-M4 (RTOS: uC3) FW , an error message is output on the console of Linux.The steps when an error...
Hi.I was going to buy STM32MP157C-DK2 but its status NRND(Not Recommended for New Design). So I think to buy STM32MP157F-DK2. Are they different point is only a clock(650 or 800) of A7 core? What's the difference?Thank you.Best regards.
I want to know what "st-image-xxxxx" parameter mean.Especially, I want to know what name of xxxxx (for example "weston") means.Is the name of xxxxx related to the name of some config file?For example, if I changed the name of xxxxx to any name from ...
We would like to share data between the A7-core and the M4-core on an STM32MP1 device. Those cores both have access to the SRAM1,2,3,4 . The M4-core is connected directly via the AHB interconnect, the A7-core is connected via the AXI-based NIC-400 in...
Hi.It's ready to use MP1 peripheral(USB, Ethernet, SD card) right away if I download to OpenSTLinux image to MP1-DK board after downloaded on ST website? or Do I need to make device driver for peripheral?Are there guiding, or tutorial for making appl...
I found that the UBoot env stored at the same address as the bootfs, which caused emMC to fail to start the kernelEnv and Uboot are both at 0x280000 addresses,
