Hello,I am working on IPC between M4 and A7 and it works properly using the "logic analyzer" example. I changed it according to my needs but not the buffers. 1 . I could read the data from 3 buffers, but often buffers are swapping. I would like to wh...
Hi STM32 MPU's community ! On behalf of ST and all ST employees involved in this community I would like to wish - to all members here - a joyful holidays period and the best for coming year 2022 !I take this opportunity to thanks you all for your par...
In a normal M4 like the STM32F466RE the MX program does most of the setup for transmitting the UART with DMA when you configure. However there is NO DMA option when setting up the UART for the STM32MP157. I dump internal information to a UART so I ca...
I am getting an error in the kernel log when remoteproc tries to "set hold boot" during startup in Linux. The error is:remoteproc remoteproc0: failed to set hold bootremoteproc remoteproc0: releasing m4stm32-rproc: probe of mlahb:m4@10000000 failed w...
Hi allFor test purpose I want to run a real-time kernel on the STM32MP157c-DK2 with the newest ecosystem 3-1-11. The goal is to develop a real-time kernel module, out of the Yocto environment.I did build the Image with Yocto and flashed the image. Ap...
Hello GuysI'm using a157-EV1 board and my custom board.Both board have sd card slot and emmc. And possible of linux install to sd card and emmc.Anyway if built images using STM32_Programmer_CLI in Ubuntu environment can be install on the board accord...
Hi STM-Team,I am working with STM32MP157F-Eval board. I have enabled and tested secure-boot flow as per https://wiki.st.com/stm32mpu/wiki/STM32MP15_ROM_code_secure_boot.Now, I am looking for next security part for singing-verification of kernel & DTB...
