Hello,ST has released the STM32MP1 and the newer STM32MP2 series of MPU products. I would like to know what the roadmap looks like after the STM32MP2.Is there any information available about the next-generation STM32 MPU family (e.g., a potential STM...
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,...
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...
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...
I've inherited a custom board that contains (among other things) an STM32MP135AAE3, an eMMC, and an Ethernet controller (DP83826ERHBR). No SD card, no HDMI, no keyboard. For that matter, no JTAG (board error). I had thought about running Zephyr but...
The STM32MP135AAE3 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 e...
