You may download either or both. I suppose they are very similar.

UM2488 is User manual for STM32H750B-DK, you may know dual 512M-bit NOR (U1+U2) or single MT25TL01G (U1) on your board with the document.

[ZExpo.1]

I made a bare-bone setup using https://github.com/STMicroelectronics/stm32-mt25ql512abb and setting QSPI Flash as specified in the touchgfx

I am trying to get the Flash Data but the debugger is going into hard_fault interrupt

void HardFault_Handler(void)

{

/* USER CODE BEGIN HardFault_IRQn 0 */

[ZExpo.1]

I was able to write to External Flash using STM32CUBE Programmer as shown

>>STM32H750B-DK uses dual MT25TL01G or MT25Q512?

You should be able to check by inspection.

The MT25TL01G contains two 512 Mb die side by side within the single 16-pin SOIC package, so functionally equivalent, but then only one part populated.

[ZExpo.1]

I have MT25QL512 (2 PHYSICAL MEMORY) on the board.

>>Could You please specify how to remove block protection?

You'd read the Status Register in the Micron device(s), clear the BP bits, and then write them back. In this dual configuration the Status Register would be a pair of bytes, and the bits in each.

this shows the nor flash not protected (8387 readout)? You may double check by writing different content and resetting the board.

[ZExpo.1]

I have double checked that I am available to write data on the external flash, starting address is 0x900000 and what is the ending address for flash so I can write the full flash check .
