Dear people,I do not understand the following behavior of the STM32H755ZI:I implemented a stack test by configuring a safety zone with MPU. When the stack overflows, the MemManage Handler is called. So far so good.In this MemManage Handler I only sav...

Hello everyone,I am working with STM32H755ZI,, ARM GCC and J-Link GDB.Considering Reference Manual the H755ZI has following Memory Map (cutout):...0x40007C00 - 0x40007FFF UART8 0x40007800 - 0x40007BFF UART7 0x40007400 - 0x400077FF DAC10x40006C00 -...

Thanks for your answers.@Uwe Bonnes Yes the clock is enabled. I use the clock settings CubeMX prepared for me. If the clocksource is missing, the HAL UART_Init would return HAL_ERROR, but it doesn't. It returns HAL_OK.And I use the same driver for u...
