Many thanks for your help!Currently, we are using the SRAM4 memory as a shared RAM mapped between the M4 and the A7 cores. We have a Linux application that writes full 32bit values from the A7 core, as in the following snippet: *(volatile uint32_t...
I am looking to transfer large amount of data from the linux userspace to the MCU shared memory (MCU SRAM3) using the indirect transfer method:https://wiki.st.com/stm32mpu/wiki/Exchanging_buffers_with_the_coprocessorI would like to use the MCU SRAM (...
I am using an STM32MP157D-DK1 eval board, and I am looking to run a barebones linux image with the LCD-TFT pins disabled, so I can use those pins with the M4 core. Is there a pre-generated image that does not use the LCD-TFT (HDMI) peripheral? Othe...
The STM32MP1 example code on github targets the STM32MP157C on the STM32MP157C-DK2 and STM32MP157C-EV1 eval boards, however both of those boards are obsolete. I am using the STM23MP157D-DK1 eval board.How do I port the example code so that it target...
I have two NOR flash in my hardware. On SoM (Boot meadia detecting as NOR1 in Uboot)On Carrier Card Both are detecting in Uboot as Nor0 and Nor1 but in STMCube programmer i am not able to flash to Nor1. Tool given NOR1 not found error. So not a...
Hello,Sorry for a long post this needs some context.I've been configuring and testing OP-TEE from the following guide:https://wiki.st.com/stm32mpu/wiki/How_to_configure_OP-TEEI'm using the STMicro fork of optee_os (tag 3.16.0-stm32mp-r2), and the OP-...
Hi, I use boot1 pin as gpio key function. The boot1 is PI5, and I configure it in kernel dts code. When the system boot up, the input event0 device is shows, but I use hexdump can not get any key code data. Currently, my board is boot from sdcard. gp...
1. Can the display interface be driven by the M4 core while the A7 core is powered down?1a. Can the AXI interconnect peripherals be driven by the M4 while the A7 cores are powered down?2. Display controller - is there any loss in performance if using...
Hi all,I updated my project from Morty (2.2) to Kirkstone (4.1). After doing the required fixes/updates on the recipes, I have problems booting the FSBL. I am using the Cube Programmer to flash the image. Below is the log:STM32CubeProgrammer API v2.1...
Hi ST Community, We have planned to use STM32MP131A MPU in one of our custom designs with low power consumption as the main target. We have come across STM32 CubeMX v6.8.1 for estimating the individual current consumption in various modes and whi...
