Ask questions and find answers on STM32 microprocessors, including hardware, power, DRAM, flashing, interfacing, device tree, and peripherals.
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...
Hi team,I'm developing a our PCB equipped with STM32MP151AAA3.Are the following pins named "Unused" okay to remain open?VDD_UnusedVDD1V2_UnusedVDDA1V8_UnusedBest regard,
