STM32H5: Getting the provisioned state from within the firmware
Hello, we are using a STM32H5 with TZ disabled. In firmware, we are doing the following:- set the product state to provisioning (0x17)- provision the debug authenticationThis already works fine. Afterwards, we can do a discovery an see the validity o...
Boot STM32H7Rx using SPI?
Hi, I want to design a board using a STM32H7Rx device that has only one Octo-SPI. I need this Octo-SPI to connect to an on board FPGA, so I can not use it for booting. Therefore I have some questions:Can I boot from standard SPI? I do not need to run...
BOOT0 sampling timing
Posting mostly to record some data on a pretty data-free topic. How long after reset is released does the state of the BOOT0 pin get sampled? On the STM32F413 in particular, but it would be good to know how consistent the spec is. The official docs a...

Help Choosing the Right STM32 Chip for My VCU Project
Hi everyone,I started designing PCBs last year and have completed a few projects using Arduino and ESP32. For my new project, however, I need to use an STM32 microcontroller. I could technically use an ESP32 as well, but STM32 is more suitable for in...
Can the STM32F103 perform a delay of 62 ns or 125 ns?
Hi.I'm not very familiar with STM32 yet.Can STM32F103 delay up to 62ns or 125ns to raise GPIO and lower it again during that time interval?Thank you :)
