Sir I want memory map of flash memory for STM32G071RB NUCLEO board. Which have flash memory of 128kb so I want memory adress of Bootloader, application and Bootloader size. I have tried searching for this information on various datasheets and websites, but I have not been able to find it. Could you please help me with this? Thank you.

Hi, I had the issue that the boot loader would not jump into the application. Although it worked following the steps in the video it didn't work anymore on following power cycles.
I had to disable the systick to have it working consistently all the time. Probably the flashing of the application changed the timing enough so the systick interrupt does not fire when jumping to application.

Very Good Series. Keep it up. Thank you.👍

For nucleo F303RE what are the flash memory addresses? Its not working for this board, though compilation and flashing proceeds OK, seems.

Nice video to understand I have a doubt here. Without modifying application source code can we able to flash bootloader bin file with some changes?

Thank you very much. This was a very helpful tutorial series. I am using STM32F103C8. So, I have to set the application's MSP value before calling app_reset_handler() in the bootloader. After this, everything worked fine. I hope you will continue to make videos like this :)

Wow iam searching this kind of video for long time..thanks much

[SumitAdep]

can i say vector table is defined in start file ?

[vinothkannan]

these bootloaders were implemented using pooling method
is there ISR based bootloader implementation available ??

😇 nice tutorial for beginners in bootloader and stm32 microcontroller.

Hi.Can you please help me out, .bin file was not created for me.I am using the STM32H7A3ZIT6Q microcontroller.

Hello Sir, I have referred the whole tutorial is really simple and perfect.
I had a doubt that can we say that the application you are referring here maybe the firmware of the board.
And if its yes than can we add a security check for the firmware update process in the boot-loader itself or is there any other way to secure the firmware update.

hi i like your video very much and have been following your video, i have done the steps u provide in the video, question is how can i erase this bootloader that i had programmed? i m using STM32H7A3 Nucleo board

Hello, I did the whole procedure on a NUCLEO-F446RE card but it doesn't work, nothing happens when trying to jump to the application, could you please explain to me if I need to do something additional for this microcontroller?

[fernandocastro]

Thank you very much for share your knowledge. Waiting for next part. Really nice tutorial with a good explanation. Keep doing videos like this.

Hi, please why did you exactly add 4 in (0x0804000+4)

[rahulr]

hi sir, can you please tell us what version of stm32ide you have used in this video?

[incxxxx]

Why the pronounciaton is so bad ??? It is hard to listen.

You just implemented a basic bootloader in single video hats off to you!! Subscribed!!!! ❤
