Hi!Problem: The board boots correctly into the Linux kernel, but the kernel is unable to mount the rootfs.We designed a custom board using stm32mp157f. It is based on the DK2 with some differences:PLL Base clock 48Mhz (instead of 24MHz)Other power su...
CK_SCMI0_HSE is a syntax error when compiling with dtc, but it does not exist in the file stm32mp1-clks/h. Is it okay to set it to CK_HSE?
Hello everyone,I need a way to synchronize A7 and M4 cores (find the same timestamp) within 1 ~ 2 usec. Is there any shared timer or resources except for memory and virtual serial com between these two cores? I have a PPS signal and I want A7 to be a...
Hi ST Community,I have been trying to add the WLAN interface to my stm32mp157f-dk2 board with the distro "openstlinux-weston" and the machine "stm32mp1" without success with the following documentation:I have applied the kernel configuration given in...
Hi! I have created a program to send messages between cores (A7 and M4), using virtual uart. The messages that are sent from the A7 core are received by the M4 core. My error occurs when I try to read the messages that are sent from the M4 core to th...
Hello, I would like to disable the thermal shutdown at 120C on STM32MP157A-DK1 which embeds a STM32MP157A. It runs Yocto Project and contrary to other boards I worked on, I cannot turn off and even change the critical temperature (the procedure is th...
Hi,I'm using stm32mp153c and I managed to start M4 code after the SPL initialization and before U-BOOT. All initializations work fine except for the MX_OPENAMP_Init.I see that if I start the code after SPL the variable of num_of_vrings (that is equa...
Hi there, I've got an STM32MP157F-DK2 devkit, I managed to set up all the packages, including Yocto distribution (Distribution Package) and all seems to be working fine for me. Now I'm starting to modify ST distribution, just to get used to the envir...
Hi there, I'm starting developing on an STM32MP157F-DK2 kit, and I wanted to build my own distribution, starting from the distribution package (STM32MP1 Distribution Package - stm32mpu). At the first compilation, the bitbake st-image-weston takes rea...
Hi, I have upgraded to Ecosystem 3.1.1 and have started to get warnings in TF-A when booting up my stm32mp151c. These are the warnings: NOTICE: CPU: STM32MP151CAA Rev.B NOTICE: Model: STMicroelectronics custom STM32CubeMX board NOTICE: Bootrom aut...
