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...
I'm using a custom board, and use the optee device tree generated by STM32CUBEMX and full UART log. Panic at core/kernel/dt_driver.c:904 <probe_dt_drivers>. How to solve this problem?
Hello ST Community, We are developing a product based on STM32MP151 which has 2 (WKUP) GPIOs connected to wake our battery-powered product from sleep or shutdown. Can somebody please let us know how we can detect which GPIO triggered the wakeup in li...
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...
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...
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'm facing a problem when trying to build an image for my mp257f-eval board using a custom device tree generated from cubemx. I've followed the instructions from the following wiki : https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_wi...
So coincidental enough all the projects I have done before required a RTC /w LSE. I am now working on a project that does not need a LSE, and I am finding that TF-A keeps throwing a panic because of this. The protos we had fortunately had the circuit...
Hello everyone,I'm experiencing an issue with network packet loss in a setup using the AR8031 PHY with an STM32MP1 system and would appreciate any insights or suggestions.Problem Description:Significant (60-90%) packet loss when STM32MP1 board is dir...
My freshly arrived and assembled STEVAL-ROBKIT works well in Autonomous and Follow-Me mode but not in Drive. Nor does the "lock" toggle seem to do anything. Lock does not stop Follow-Me if activated. Any ideas?John FergusonSt Petersburg, FL
