Hi everyone,we applied the ST FWU reference solution on our own platform based on the STM32MP157F.The solution was taken and adapted from the ST Yocto layer meta-st-ota (https://github.com/PRG-MPU-CUST/meta-st-ota).We have a few questions to clarify ...
I have CubeMX 2.0.0 and I notice that if I want to enable DSIHOST, I need to first enable HSE.But the clock configuration of the DSI does not require HSE. It seems that the clock configuration of DSI seems to work with HSI in CubeMX 2.0.0.So, the que...
I have an STM32mp135f-dk board that I have been using openstlinux-6.1 to develop images on.For my board, I made a custom device tree "iris.dtb" which I intend to use instead of the default "stm32mp135f-dk.dtb".I ran into an interesting issue where u-...
Hello,We have designed a custom board based on the STM32MP157F-DK2 platform.The design uses the STM32MP157FAC MPU and includes the following peripherals:MicroSD (SDMMC)STPMIC1 PMICDDR3L memoryEthernetUART4 for console My power sequencing, PMIC wiring...
The board was designed incorrectly, they have pins for a JTAG but forgot to actually route them to the MPU. The eMMC is not going to have a first-stage bootloader on it, and it's looking like it's not possible to flash an SPL to the eMMC over USB al...
In AN5489, the HSE is recommended to have 40 MHz. Why 40 MHz?Why not 24 MHz HSE? Is 40 MHz a specific value for a certain pheripherial?
Hi,I am new at STM32MP2. I have a stm32mp25f-ev1 board and I was able to build the distribution package and to run it on the board.My next step is to build an image for my own board that was designed using the eval board as a reference, but with many...
Hi,we use the STM32MP157C with almost the same RAM layout as the STM32MP157F-EV1, except that the SDRAM chips are from Micron (MT41K256M16). The PMIC is also the same as the one on the evaluation board, and the settings therefore are identical. TF-A,...
Hi I was trying to connect a custom LVDS display to my STM32MP257F-dk board but it does not seem to work, The display has a resolution of 1024x600 pixel and also it uses "vesa-24" scheme, so i assume that i don't need to change the device tree as it ...
It seems Azure® RTOS might be able to run on STM32MP135AAE3, the "Introduction to Azure RTOS with STM32" says "All STM32MP13x lines are covered by default by Azure® RTOS middleware within the matching STM32Cube MPU packages" but I'm having trouble fi...
