These are the ECCN for these processors. The code for MP1 and MP2 are different. When purchasing parts from retailer in the USA, an export authorization check was done on their website (no idea why) and retailer said they had to wait for the US agenc...
Hello,I am trying to understand this document:https://wiki.stmicroelectronics.cn/stm32mpu/wiki/How_to_deploy_SSP_using_a_step-by-step_approachGenerally speaking, I miss some context between the "SSP is nice to protect your firmware through HSM" and t...
hello team I have designed a custom board based on the STM32MP157FAC1 and would like to request a review from experienced members to ensure its correctness and optimal performance. I have attached the schematic for review.
Hello ST People !I'm looking for information / possiblity to use SPI (via spidev & ioctl) in Linux user space with DMA.We have to transfert lots of data (4000bytes at one time, very very often) to a fpga, very quickly and we are facing latency issue ...
Hi,at https://www.st.com/en/evaluation-tools/stm32mp257f-ev1.html# the CAD-data of the STM32MP257F-EV1 evaluation board are provided. This imports well into KiCAD, however nearly all footprint data are missing. For cpacitors and resistors with standa...
Hello, I built FIP artifacts following wiki, `STM32MPU Developer Package`, 5.2. Installing the OpenSTLinux BSP packages.And I could get binary files:1. TF-A binary: tf-a-stm32mp157d-smp4-mx-optee-emmc.stm322. OPTEE binary: tee-*.bin files3. u-boot bi...
Hi,I'm working with an STM32MP257-EV1, and security is managed by OP-TEE. I'm trying to dynamically modify PMIC voltages from a Linux module.I've read that the PMIC is managed by OP-TEE via the SCMI subsystem.I tried calling the Trusted App SCMI from...
HelloI have a cutom board based on STM32MP157D-EV1.The dts is based on stm32mp157f-ed1.dts with minor differences:* HSE: Bypass -> crystal (There is a 24MHz crystal). Removed "st,digbypass;" from &clk_hse* DDR: 32bit 8Gb -> 16bit 4Gb. (Using MT41K256...
Hello,We are researching the possibility to protect different pieces of our software on Linux (OpenSt-Linux) and firmware for the M33 on the STM32MP257.Our goals are (mostly) aligned with the purpose of the SSP HSM mechanisms:1) Avoid our firmware to...
Dear ST Rep, The information within AN5489 regarding the pin-lengths for the high-speed serial interfaces of the MP2 (ie,. DSI / CSI / LVDS / and "COMBOPHY") potentially has some errors, or at the very least is unclear and I would greatly appreciate...
