What is the MIPS figure for X-CUBE-CRYPTOLIB HMAC SHA-256 Implementation for STM32F429 (Cortex M4)?
Hi, I'm looking into introducing HMAC SHA-256 on my STM32F429 based project as part of a requirements change. As a first go/no go, I'll need to know what is the worst case required MIPS figure and memory foot print (SRAM/FLASH) for running the algori...
NUCLEO-H745ZI-Q SBSFU adaptation cannot boot CM4 image.
Hello, I am trying to adapt the H753xx SBSFU implementation to the H745xx dual core board.I have so far configured a second slot by creating a second MPU region of 1KB to protect the header of the second slot, as well as changing the security checks ...
