Ok Thanks for the input, I have set the output to .srec and tried to program as specified by you and got the following results

[jiangfan]

Your previous operation at 2nd tab was OK to erase NOR flash, you may try in that way.

[ZExpo.1]

[jiangfan]

oh, almost the same status as the first post.

Well, you may try the following to avoid side effect:

1) erase internal flash

2) power down and re-power the board

3) do the programming again (I mean, previous operation at 2nd tab)

There is strange point for me: "Board : STLINK-V3MINIE". I suppose the board name information should be "Board : STM32H750B-DK".

[jiangfan]

one point to take care about QSPI NOR flash programming on STM32 board: be sure to use latest version of STM32CubeProgrammer (v2.14.0).

[ZExpo.1]

Yes I am using the latest STMCUBEPROGRAMMER.

Going to observe here that if you run algorithms for other vendors devices against a Micron part that you can inadvertently lock blocks on the Micron device precluding write and erase, including mass erase, from working.

In these cases you need to remove the block protection level from the status register to recover the memory. 

[ZExpo.1]

Could You please specify how to remove block protection?

[jiangfan]

MT25TL01G datasheet will tell you.

[ZExpo.1]

STM32H750B-DK uses dual MT25TL01G or MT25Q512?
