Program bin file from Cube Programmer

[MGogr.1]

I have two stm32f429 Discovery boards. I programmed one of the board using cube ide; the output of which was as expected. Then using cube programmer I read and saved the bin file from that board. Using that bin file I programmed my another board which was successful, but there was no output.

Is there any another method to do this?

I am doing this because I want to save bin file from my custom board and program it to another board and I don't have original code.

Besides the flash, there is also the user/option bytes area. You may want to compare those with STM32CubeProgrammer. 

Otherwsie, if you save the *entire* flash as .bin, the boards shall behave identically.

The only exception is if the firmware actively works against that, like by evaluating the unique device id etc..

I compared  both the files and it says no difference found. But no output in second board.

Same model / build / revision of STM32F429I-DISCO ? Not a DISC1 ?

>>But no output in second board.

Screen? Or USART/VCP ?

So probably not recovering and writing enough. There's 2MB of FLASH, so 0x08000000 to 0x081FFFFF
