I can't programm MT25QL512ABB8ESF-0SIT flash on STM32H747I-DISCO Discovery kit

[DVino.1]

Hello!

I can read any registers, but can't proramm it. This is my first attempt to work whith this flash in this KIT. Initialization - HAL, STMCube IDE.

Code in main function after Initialization (initialization - auto generate in IDE):

There are no any warnings, or errors during compilation.

Then i sent data (qspi2rd[]) to USB. Result: flag status regiter = 0x80 (ready, no errors), status register = 0x02 (Write enable latch set). But in Volatile configuration register and Enhanced Volatile Configuration Register 0xFB and 0xFF respectively. Oscillogram accordingly Micron Serial NOR Flash Memory datasheet. Where my mistake? Mey be i must sent any other command? Nonvolatile Configuration Register = 0xFFFF (default state).

>>There are no any warnings, or errors during compilation.

Really just means the compiler didn't find any syntax errors, not that the code is free from logic or algorithm errors.

Would probably start with the BSP example code, rather than the auto-gen stuff.

The QSPI parts are double banked on the H747I-DISCO as I recall. If configured properly alternate bytes go to each device.

I try to use stm32h747i_discovery_qspi.c from BSP example code in my test project. But i can't programm registers or memory analogically. May be i don't take into account something? All stm32h747i_discovery_qspi functions returns BSP_ERROR_NONE. Code in lines 187-196. Flag event (line 186) happens once a second, when timer interrupt occurs. QSPI_Init declaration in line 63, QSPI_Init initialization in lines 82-84. QSPI init in line 149. When i try to use MT25TL01G_QPI_MODE flash doesn't work.
