Ask questions and find answers on STM32 microprocessors and dedicated embedded software solutions, such as Yocto SDK, Qt, and OP-TEE.
Hi,i want to use the secure storage feature of our custom STM32MP151CAA based platform. Therefore i have to write a HUK to the OTP as explained in the STM32MP1 wiki article. But how do i generate a HUK? What exactly do i have to program into the OTP?...
Hi,i want to enable optee-os for our STM32MP151CAA based platform. We use upstream TF-A, OPTEE and Barebox-Bootloader (very similar to u-boot), not from the yocto st layer. Yocto version is scarthgap, OPTEE version 4.1.I was able to switch from sp_mi...
Hi,I am using the stm32mp157-disco board and trying to mount one of my sd card partitions to my linux VFS at boot time with systemd. I have modified the file /etc/fstab, adding the following entry:# <file system> <mount pt> <type> <opt...
Hello We have custom board with STM32MP257DAI3 Processor.We would like to test it using Buildroot. Could you please advise whether it is feasible to use the STM32MP257F-EV1 Buildroot configuration for testing our STM32MP257DAI3-based custom board? A...
I am working through the MPU Wiki guide Develop on the Cortex-M33 for STM32MP257FI am running the FlashLayout_sdcard_stm32mp257f-dk-ca35tdcid-ostl-m33-examples-optee.tsv image.I can successfully load and debug binaries for the M33 and the virtual UAR...
HelloI am working on the multi-system in STM32MP257-EV board, I had modified the tsv file to prepare a double system A and B. If using the default metadata.bin file, the A system will be run always. Now I want the B system to be run, I need to modify...
Hello,I want to use a virtual keyboard on STM32MP257 now. Due to the possibility of porting some non Qt applications in the future, it is advisable to avoid using Qt's built-in virtual keyboard as much as possible. Do you have any ideas.My main appli...
Hello We are currently working on reading NOR Flash(MT25QL128) device ID through OSPI interface on our custom board with STM32MP257D processor. During our testing, we observed an issue where no data appears to be written into the OCTOSPI Data Registe...
Hi all,Following the guide at https://wiki.st.com/stm32mpu/index.php/How_to_create_your_own_machine, I generated Device Tree .dts files using STM32CubeMX (version 6.14.1) for the STM32MP257F-EV1 board (selected via Board Selector) in a project named ...
Hi I am currently working with an STM32MP135F-DK development board. My goal is to compile and execute a simple C program on this board.While I have successfully booted the board and updated the operating system using my laptop, I am finding it diffic...
