Lecture 15: Booting Process 

Nice explanation, prof. Hawking!

That's really useful! I looked pages of Reference Manual and still don't understand memory mapping to 0x0000 0000, this video explained it very well.

Great one. Loved the way the whole process is presented. Thank you very much, professor :)

Indeed the best Tutorial on ARM Cortex-M Processor booting mechanism!

I was always confused about how a processor starts from the very 'beginning' but this video cleared my concepts, thanks a lot. Now I know exactly how things start from the very beginning. Hard to find such clear explanation on the internet. Thanks..!

very precise. great job sir!

nice description, very much helpful (100/100).

best video ever 10/10

very good lecture! Clear and Simple!

Explained booting concepts in detail.

Clear and Simple. Very helpful Thank you

I've been looking for this

Thanks for video! Is it possible to say that boot mode is arranged for flash memory as default?

Excellent explanation as always by Prof Yifeng, Thank you very much for your time and efforts.

Detailed explanation and getting same concept from book is hard compare to urs. :) Thanks :)

Very well explained sir. Thanks for the info!

Could you please provide kindle version of your book, because It's very inconvenient to purchase your paper book in China.

受教了，朋友，加油，你最棒

Thank you for this video .its very helpful

great, will u please share power point slides for this demonstration?

great video.

Best explanation, thank you 👍

Awesome! Thanks!

How are SP and PC set when the boot is from SRAM? SRAM will have some random values on reset

Awesome, a video that doesn't assume the viewer the viewer is a scriptkiddy

the describe about boot from ram might be not correct . actually on stm32f103 boot from ram is same as boot from system memory. the bootloader senses the pin configuration than transfer excution to ram. but not alias ram to address 0

brillant !!

This is such a great explanation . thank you sir

Good explanation

Good job! Thanks for sharing.

Great!

thank you

Excellent lecture and explanation 👍.

감사합니다.

Hi Professor, At 7:43 , you say - "In the Boot mode, processor can reprogram the Flash memory or Perform the device firmware upgrade". Please can you help me understand : 1) Why reprogramming the Flash memory is done ? 2) Please can you make video on "How device firmware upgradation is done by BootROM(boot memory). Can you please point me some resources to read. Thanks 🙏

This is the real hacking. thank you

Hi This info is very useful ,but I have a question that when system clock is initialized and explain me those steps sir

What is Main Stack Pointer (MSP) ?, does MSP point to memory location of boot because video at 6:57 state Physical map Ox08000000 to Ox00000000.

Hi, are these contents coverd in the book ?

Can we design in such a way that stm32f100 handle 2 or more main() function ? If no .. then how to design bootloader for this ?

Sir, what exactly happens inside Reset_Handler?

I am using STM32F103c8t6 MCU with IAR IDE and when testing the startup code, the MSP and PC registers are initialized from addresses 0x08000000 and 0x08000004 respectively without any aliasing from address 0x00000000! Kindly note that the .intvec value in IAR is set to 0x08000000 value. So, is there any problem with that?

100hun！

you are the best : 你最棒 . Is this correct in Chinese ? :D

This is how im gonna turn old xboxes into linux gaming pc's.
