Hello everyone,we have developed a custom board based on stm32mp157 chip. We have also forked the tf-a, optee, u-boot and linux-kernel from meta-st-stm32mp layer. We have the following configuration for the tf-a and u-boot. NOTICE: CPU: STM32MP157C...
i am planning to build an dpoae device so which one do u prefer STM32MP157D-DK1 processor or STM32H7A3 microcontroller is enough? for STM32MP157D-DK1 can u suggest some videos on how to use it ,the ide for it how to access the GPIOS .u can also sugg...
can you please suggest me a best stm32processor board which has adc and dac and usb port, ethernet wifi which uses stm32cube ide
Hi, I have customized a board using STM32MP157DAC referencing the mp157d-disco board hardware design. I have discrete power supply. I deleted the PMIC related nodes is DT and add fixed regulator in the root. The TF-A boot is ok, but the optee panic w...
Hello! Thank you for opening this post.This is my first time to fully build the Distribution Package according to the guide on ST Wiki, and I have gained a lot from it.But now I have a question to ask for help. After I burned the generated image afte...
Has anyone encountered issues with unstable clock configuration on the STM32MP135F? I'm having trouble achieving a stable output, and adjusting the PLL settings doesn't seem to help. Any suggestions on how to fix this?
Hello,I want to control STM32mp157d-dk1 GPIO from python i tried to use libgpiod but apt-get install python3-pip not work for me
Hello everyone, I am trying to program the STM32MP157 to control a simple LED using Keil software. However, I am encountering numerous errors during the compilation process, particularly with the setup files. Additionally, the controller name appears...
Hi,I am debugging the STM32MP257F-EV1 board with a debugger via JTAG/SWD. The kernel version is 6.1.82.Since the A35 cores are in break state/stopped during debugging, I want to disable the watchdog timer on U-Boot/Linux.I have tried the following wa...
We have a custom STM32MP157 board running Linux that is not booting over eMMC. The STM32MP157 image boots from SD card on SDMMC1 but not from a Toshiba THGBMNG5D1LBAIL eMMC chip connected to SDMMC2. We have confirmed the Boot pins are correct, and th...
