Hi everyone,We have developed a custom board based on stm32mp157 mpu. We have used openstlinux distribution and the branch is "kirkstone". We have interfaced edt_ft5x06 display. Display is working perfectly fine but problem arises when we try to inte...
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...
