Program bin file from Cube Programmer

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.

Did you even understand what I want to do?? Or should I explain it again!

I'm using .bin file to program my board. The output of which should be simple PWM pulse which I'm not getting.

So its not a hardware issue as I'm using STM Discovery boards to test my setup. Since its a bin file I can not check in Disassemble / Debug nor it can be Stuck in Error_Handler() or HardFault_Handler().

It can be a problem of Cube programmer not programming properly or steps I'm following are not correct.

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