Hello,I am currently engaged in a project that involves using TrustZone to securely display an image on the STM32MP135F-DK. I'm facing several challenges, especially in configuring the framebuffer for secure display purposes:1. Running the 'hello_wor...
hi, is there any source code or document about STM32PRGFW_UTIL_MP13xx_CP_Serial_Boot.stm32
Hello,I would like to set up the PMIC for the MP13 series using Baremetal. The provided PMIC-related documentation appears to be related to Linux. Is there any documentation or example available for using it with Baremetal?Thank you.
Hi st team, I am using the STM32MP135f-DK board and I want to enable CANFD drivers. First I checked if the CAN drivers are enabled in menuconfig using: bitbake virtual/kernel -c menuconfig (everything has been selected) Then I went to ~/STM32MPU_wor...
I could not complete loading a board following the WiKi How to load U-Boot with dfu-util.The process describes sending the tf-a file then the fip file however this always fails the correct procedure is to send the tf-a file then send the flashlayout ...
I am trying to interface DAC for the STM32 MP157D-DK1 board I have. I am just curious does the board even support DAC. I dont see any mention of that in the datasheet. That is the only option that I can select when I do DAC Enable for M4 Cube in cube...
I'm having a challenge moving changes from our Developer Package to our Distribution package. We've modified device trees using CubeMX for our board and have all the changes for TF-A, optee, u-boot and the kernel working in the Developer Package. Now...
The processor in this application is an STM32MP153. I'm using a Cypress FX3 emulating SRAM so I can use a read path of FMC->MDMA->AXI memory-to-memory and vice versa for the write path. Two independent hardware interrupts on the STM32 GPIOs initiate ...
