Resolved! Can I use ALL of STM32H750's SRAM for continuous data?

I'm not having any time critical routines so I'm hoping of using all of the MCU's 1MB of RAM for data. As I understand from the RM, RAM is organized in a several banks. Can it be used as a continuous chunk of 1MB for data?

Resolved! F4 and F7 SPI CLK waveform

During testing an SPI DAC (TI DAC8563) on an STM32F446RE (where it works) and on an STM32F767ZI (where output is always 0V), I noticed a different SPI clock waveform.In F4 you have three "8 pulses" signals from CLK (the message from MOSI is 24 bit), ...
