Thanks for the video. It really covers all the nooks and corners to bootloader development in a not-specific-to-any-hardware way. and that is really awesome.

Thank you very much for this great informative video, looking forward to future video's. Good embedded engineers that share their knowledge in a way someone can understand are very scarce. At the moment I'm in my final year of my EE study, the bootloader was never mentioned... Before this video I thought it was black magic.

@22:40 it would be great if we have translators between assembly codes of various manufacturers that help facilitate the code transition to another manufacturer.

Hi Jacob, thank you so much for this video. A wonderful overview plus lots of points I hadn't considered. It's five years since you posted this video so it's not unexpected that your bootloader design workshop is no longer on your website! ;) If you happen to see this comment, could I please ask if you have anything else on your site with more on bootloader design? Thank you.

@beningoembedded 2 жыл бұрын

The course is still there, it just lives at beningo.mykajabi.com/ now. The lecture materials are still accurate, but the lab materials need a refresher. Hopefully something I'll get to later this year.

@21:32 for low count pin MCU we can set the code to poll for the zero logic via the switch for 1 second after power up, or so - and after say 1 second from power up the code flow goes automatically to program, not bootloader, if low logic is not detected. So before you power up you just press and hold the switch then power up - this guarantees that the MCU will enter bootloader code. I have done such a similar design before. Then re-use that GPIO pin for another task.

@jacob_beningo Ай бұрын

1 second is a very long time in a lot of application. In some industries, there is a requirement for this entire process to take less than 1 millisecond!

Nice video. I always wanted to learn about boot loaders. Is it possible to write a boot loader for 8051 core? Like 89s52 microcontroller. Thanks in advance.

Absolutely! A bootloader can definitely be written for a 8051 based part.

@MorningStarChrist 3 жыл бұрын

Where do you find documentation on what system calls are available to a programmer building a boot loader? Since linux has it's own set and what not, what kind of documentation exists for bootloaders? how do people know that mov ah, 0x0e mov bl, 0x07 mov bh, 0x00 int 0x10 will print a character to the screen?

@jacob_beningo 3 жыл бұрын

You have to look at your parts datasheet. The low level assembly instructions are typically only used for jumping to the application to reset the stack but there are other ways to do that too. A good place to start is with the example from the silicon vendor you are using.

Was there a follow up of this video?

@beningoembedded 6 жыл бұрын

I haven't posted any follow-up videos specifically on this topic. However, I do webinars that follow these style every few months that cover a different embedded topics. I advertise these in my monthly newsletter that you can find at beningo.com . Specifically for bootloaders, there is a white paper I created a while back that you can find at www.beningo.com/insights/white-papers/bootloader-design-for-microcontrollers-in-embedded-systems/ . I also have a course that I put together that you can find at www.beningo.com/services/workshops/. You can also find bootloader articles and other webinars using the category filters on my blog at www.beningo.com/blog/. I hope this helps!

@Kefford666 Жыл бұрын

That memory map allocates a whole 1KB page to the boot config byte. You said you write a string there rather than a whole byte, but do you write anything else here? It seems like a waste of a flash page if there isn't much written there.

@jacob_beningo Ай бұрын

You can write other information there that might be useful. It does seem like a waste, but 1 kB in many hardware solutions today is not that much.

+Jacob Beningo Hi sir.. From your tutorial's learning. I have come up with a boot loader. But I am facing an issue here. My Boot loader logic is this, Configure a button as Boot loader Button, If you press that button, the program goes into boot loader mode, where it just checks for any User Application. If the button is not pressed, it will go directly into Application mode. The controller for which I designed a boot loader is MKE02Z64VLD2 microcontroller (KE-02Z). I am using Terminal Application (sites.google.com/site/terminalbpp) for sending an Application file serially. My serial connection to my custom board is Half duplex :( adding fuel to the fire, the MKE02Z64VLD2 microcontroller does not support RTS and CTS. Can you suggest me anything ?

@beningoembedded 8 жыл бұрын

+Ganesh Ramachandran Break the problem up into smaller pieces. You need to identify where the issue is. Are you sending too much data at once, is flash getting read improperly, corrupt data being received, etc.
