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...
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'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
Hi everyone,I need some guidance on building a real-time face recognition pipeline on the STM32MP2 platform.My requirements:Reliable face detectionGood, consistent face embeddingsDecent FPS on MP2Preferably ONNX or pure CPU, since heavy frameworks ar...
Hi!I am working on a custom board design based on STM32MP157FAA1.I need to interface a MIPI display with the microprocessor.I am powering this microprocessor using STPMIC1APQR PMIC. As per the datasheet of the PMIC, the default output voltage from BU...
