Resolved! 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...
