Configuring OCTOSPI on a STM32H723/STM32H730

I'm having an issue configuring the OCTOSPI for accessing an external HyperRAM (Cypress S27KL0643) connected to OCTOSPI1.My basic issue is that the STM32 doesn't provide a chip select or clock when I attempt to access the chip.I'm suspect I'm misconf...

How to configure 32kHz LSE oscillator via HAL?

I think I've set up everything sensibly via STM32CubeMX to get HAL control of the LSE, but the external oscillator appears to be not operable. In particular, there is essentially no voltage on the 32kHz crystal pins, so of course it will not oscillat...

FMC for STM32 in muxed mode

Please help me with operation of the FMC module in STM32F407VE. It is necessary to connect external RAM memory; since FMC module in this microcontroller uses the address bus and data bus in muxed mode, its need to demultiplex this signals. For this p...
