Ask questions and find answers on STM32 microprocessors, including hardware, power, DRAM, flashing, interfacing, device tree, and peripherals.
Hi, according to "AN5256 Application note", I think VTT -DDR termination resistors circuitry is ok to be removed. Does it mean all things relate to VTT DDR below are also safe to remove out of the design? Many thanks
On STM32MP157f-DK2, when use UART4 which is default connect to STLink, STM32CubeProgrammer connect and work perfectly in boot serial mode.But when I change to different port (like USART3, pin PB10 and PB12 (also supported by default), STM32CubeProgra...
After reading documents, I understand the practical boot sequence of STM32MP1 is BOOTROM->TF-A->U-boot->Kernel->file systemIn my use case, I prefer to use Windows and write code in bare metal, without U-boot and device tree involved. 1 I think the b...

For a new design I need a very powerful MPU device. I would like to use STM32MP1 without Linux OS. I don't need this OS. Does it make sense to use STM32MP1 for a bare metal application? Compared to STMH747, what is the performance of STM32MP1 process...
When i use update_prebuilt cmd to build bsp component report failed,my openStDroid tags is st-android-11.0.0-2021-08-31, Can anyone help me solve this problem? error:Build and update images for primary and secondary bootloaders (programmer images) [...
I am using STM32MP157F-DK2 for secure boot. I am using ecosystem release v3.1.1 which has TFA v2.4-stm32mp-r2.1. As per steps given by ST need to fuse publicKeyhash.bin to OTP from u-boot console using "stm32key fuse 0xc00000000".As OTP area can not...
Hello,I have built a custom image using the Yocto project in the Dunfull branch. However, when I try to upload my code to M4 Core in production mode, it shows me this error message. However, I am able to connect to my board through SSH. So I believe ...
I'm using latest ST official U-Boot release v2021.10-stm32mp-r1 and I'm trying to get OP-TEE working with ST's official Linux release v5.10-stm32mp-r2.1 and it's stuck after U-Boot:Starting kernel ... I/TC: Secondary CI/TC: Secondary CPU 1 switchin...
Hi team,I am developing our PCB referring to the "STM32MP157 EVAL"(MB1263-C04 Board schematic).https://www.st.com/en/evaluation-tools/stm32mp157f-ev1.html#cad-resourcesIn the datasheet, VREF+ looks like a voltage output pin, but why is power supply...
