Your video is very informative and helpful and you are the best teacher I ever have---thanks a lot

Thank you so much sir, a lot of love from Maharashtra!

Hello. I am confused since in all the literature I have read up until this point I have been told that Cortex-M MCUs have a full-descending stack model and what it is loaded into the MSP after reset/power is the direction of the top of the stack i.e 0x200X X000.The value that you say gets loaded in the MSP is actually the direction of the begining of the SRAM memmory that leaves virtually no room for stack to grow. MSP should point to the end of SRAM (direction depends on the specific MCU but it is in the range of 0x200X X000) to allow it to grow downwards.

Thanks for your video sir. All the best for upcoming one!!!!

Hi Sir, which board to buy STM Discovery or Nuleo board? Am following your tutorials!

[cristianjulianrojassierra]

As I could do it for the STM32WB55, I see that it is very different from what you explain.

[heronumber]

I am little confused because i made the bootloader part and loaded it to the board ( stm32f407 discovery board) and it works but i do not know that how it will jump to application because they are 2 different projects in my stm32cubeIDE. I have allocated 4 sectors for bootloader and 5 sector for the application which starts from 0x0801ffff. i put this address in the linker script of application

[heronumber]

i made boot loader code it works but when i made the code for application i am getting an error " unused declaration of function __io_putchar. can you please let me know ----from canada

[heronumber]

Professor: i compared my application main.c and the one you sent me is 100 Per same but i still have the message although i do not get any error when i generate code for application

[heronumber]

where does the app_reset_ handler reside

[simonedallai]

interesting, but I can't understand what the advantages of using the bootloader instead of normal code are!

[heronumber]

Dear Professor::I am using the same code you made in your video. When i do bootloader part it is ok because I do not get any error when I generate the code in stm32IDE but when i do the application part i get this unused declration of function io__putchar (int ch) function) message in main.c of application part in stm32IDE

how to find the reset handler address in other microcontrollers

[ArunkumarSelvaraj]

Plz change teaching style... Which means voice..

[grigorianoby]

unfortunately very bad quality, nothing to understand
