I would like to use MDMA on Cortex M4 to move data from DDR to SRAM in order to overcome the SRAM size limitation, especially in Ecosystem 6 secure context when a SYSRAM bank is dedicated to OPTEE.My idea is to move to DDR some data structures used b...
Moved from MCUs forum: STM32MP13 is an MPU - not an MCU.Hello Everyone,I hope you’re doing well. I’m encountering a problem when trying to boot Linux directly instead of U-Boot on our STM32MP135F-DK board. Below is a summary of what I’ve done and the...
We are following the steps mentioned in this link How to measure the DDR throughput - stm32mpu.However we are facing the below error while trying to use stm32_ddr_pmu We inserted the lkm module stm32_ddr_pmu.ko using modprobe. The lsmod lists the stm...
I have created basic image with DISTRO=openstlinux-weston MACHINE=stm32mp25-disco, and tried to add device tree files and I have tried to switch to new device tree variant via configuration, and I am planning to emmc to flash the image, I have done i...
Hi all,i'm developing firmware for STM32MP135F-DK board to communicate with some external chips in I2C1.No problems if I communicate with other I2C chips (clockgen, eeprom, io expander).Communicating with the RTC PCF85063 chip happens that no problem...
Dear ST Team,I am currently working with the STM32MP257x-EV1 evaluation board to validate the BSP, following the official setup procedure provided on your Wiki.At this stage, I am verifying OpenAMP communication between the Cortex-A35 and Cortex-M33 ...
I am working on a STM32MP157D-DK1 board, and I am trying to follow the guide from the wiki to start the coprocessor from u-boot:https://wiki.st.com/stm32mpu/wiki/How_to_start_the_coprocessor_from_the_bootloader#Start_from_the_bootcmd I have pulled th...
Hi,I have STM32MP257F-DK and Yocto linux installed to it.I have tried to get spidev working on SPI6, but no luck so far./dev/spidev6.0 won't appear to filesystem.Has anyone tried this combo and got it working?Any working SPI configuration would be hi...
Hi everyone, Hi everyone,I’m currently designing a custom board based on the STM32MP157FAC1 evaluation board, and as part of the process, I’m working to estimate the power budget for the design.However, I’m finding it difficult to locate clear inform...
Hello~ I am using the Mickledore version of Yocto. I want to directly apply the following:meta-st-x-linux-rt-openstlinux-6.1-yocto-mickledore-mpu-v24.06.26 to DISTRO = openstlinux-weston. DISTRO=openstlinux-weston MACHINE=mymachine source layers/met...
