I've got a custom board built around an STM32MP135AAE3. It's designed to have an eMMC instead of an SD card, the problem is that the board was not laid out correctly and the JTAG isn't connected.I'm having trouble writing to the eMMC (that's another...
Dear all:I am currently using the distribution version:V5、rt 6.1.82-rt patch、stm32mp257Prompt in Wiki，need disable CONFIG_CPU_IDLE，But in reality, it cannot be closed.Why am I paying attention here? Because I encountered an Oops exception during runn...
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...
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...
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,...
