My purpose is to send an "HELLO" using a NUCLEO-L4R5ZI-P board trough HYPERBUS.
On the STM32CubeIDE, I configurated OCTOSPI1 peripherial and I/O associated.

}But when I'm debugging this program with a logic analyser I have frame that doesn't look like an Hyperbus frame.
I have 2 bytes sent then a long gap before the 3 next bytes are sent.
Also the data strobe rise on last byte sent when it should rise on each data.
