STM32 UART BootLoader HowTo

In this video, im showing:
1. What are the options available with the STM32 Bootloader
2. How to connect the UART to use as a BootLoader.
3. How to use the UART BootLoader software

Here are the links to what I have used in this video:

2:50 You explained the boot branching wrong? The node states if boot0 = 0. And you say that if boot0 = high it takes the yes branch. No, it takes the no branch because the check is if boot0 = 0 then take yes.

Great and simply understandable explanation, thank you!

Thanks a lot man, you have cleared a lot of confusion about embedded and stm32 I had before. Loved the video and subscribed.

THANK YOU FOR EXPLAINING SO CLEARLY, I WILL TRY IT AND POST YOU SOME MORE COMMENTS OR DOUBTS

[phillipnewman]

Thank you for this. It has been very helpful to me.

What if the flash loader ask for verify boot mode configuration and flash protection status?

[yaghiyahbrenner]

WOW thank you so much please do topics on this subject, been looking STM32 dual bank firmware upgrade techniques, looking for a video on the subject.. please do more :)

Is it possible to do that over half duplex rs485 line?
Thanks for your answer...

The Stm32h74x app note says that by default BOOT0=gnd will force a boot from user flash and BOOT0=3.3v to boot from System Flash But is the System Flash the same as ROM? I'd like to use the built-in (ROM) bootloader to program via CAN and/or USART.

Also, any idea if there any CAN utility (similar to serial Flasher-STM32) that can be used for in-system-programming?

is there any code using uart to debugging in stm32 please let me know if any

[ujjainwalataher]

I am using stm32 lora discovery kit and i am trying to enter the bootloader mode by following ur steps but it still the flasher gives me boot mode configuration error... I am using FTDI module which is connected as : Ftdi rx to pin PA9, ftdi tx to PA10, BOOT0 to 3.3V and normal power of 5V and ground.. but still i am getting bootmode config error in the flash and cube programmer.. both of the loader is giving me same error... can u help me out with it please ?
thank you

Can you show same thing using Linux as host?

I bought 8 STM32 cards BluePill.

I can not program them with the FTDI module.

The problem is on Jumper BOOT 0.

When I put the Jumper BOOT 0 from 0 to 1 and press the reset button the program continues to work!

the LED connected to pin PC13 always flashes even if BOOT 0 is set to 1.

I tried to program the card with the ST LINK module and it works for me.

I had to add the RST thread because BOOT 0 is not going.

I noticed that programming the card with this method presents many problems on the Arduino IDE environment.

So it is possible to operate the BOOT 0?

I realized that it is not a hardware setting but a software one.

Does anyone know how to fix it?

I really need it :(

Can you remove read protection over UART in bootloader (it will erase flash, i know)
