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...
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?
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...
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...

We are using customised board on stm32mp257f microprocessor. We have used STM32MP257F-DK as a reference for the hardware design. In our customized board, we have used LVDS panel and kept the LVDS section same as that of STM32mp257f-dk board. The boa...
