Bare-Metal MCU #4 - Bootloaders and Programmers

Thabk you, ia the programmer and six pin usb to serial adapter the same thing? I see these adapters on amazon?

These tutorials are very useful for me, thank you！

Note that erasing memory (+1m52) is done by setting it to xFF, not x00.

Great job Mr. Davis.

Hey mate I'm grateful for the content.

I've one last question in my head, is there any difference if we use USB to upload code vs doing the last process like using one Arduino to program another Arduino.
😊😊

hello sir do you have some videos on BLDC motor control with stm32 code which is in hover board i want to learn code writing for that

sir do you have some videos om bldc motor control with stm32 code which is in hover board i want to learn code writing for that

Amazing series man, thank you

Can Flash memory and EPROM be programmed by Ethernet communication? specifically when we are dealing in Modbus TCP/IP

Excelent video tutorial

Complicated stuff made simple and straight to the point. Although the content is not hard, the process of figuring it out could be hard in a sense that it's time consuming. These videos are short cuts that bypassed all the readings and findings and get you to the destination in matter of minutes. Thank you for your efforts.

finally someone that explains it correctly. Thank you!

Thank You!

I am trying to program an STM32 microcontroller without using a programmer, would this method work for that?

You rock Mitch, thanks for taking the time to make this series. Valuable content!

Mitch thanks for unintentionally answering something I had wondered if safe to do. In using the Uno to program the chip on breadboard both having separate supplies, only needing to common grounds of the USB PC supply and the battery pack supplying the breadboard.

What a amazing and didactic content! Best regards from Brazil

When I try to upload the blink sketch using another Arduino UNO as a programmer, I am getting the following error message:

avrdude: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100% 0.05s

avrdude: Device signature = 0x000000 (retrying)

this check.


avrdude done. Thank you.



Could anyone please tell me how I can go about to fix this issue?

If I program the barebones ATMega328P microcontroller using an Arduino UNO board as the programmer, am I erasing the bootloader present on the ATMega328P microcontroller? If I ever want to program the ATMega328P microcontroller via USB (after re-inserting it back onto its respective Arduino UNO board), will I have to burn the bootloader?

Can one make their own bootloader? For Arduino that is

Hello, how have you learned this interesting topics? Working? Studying? Or reading by yourself in different refences? Thank you very much!

Why do they recommend you flash a bootloader onto the attiny when it doesn't have a usb port?

Love the series! Thank you!

What is flashing of the application

Please tell me How to do the same thing with the Texas instruments MCU (like TMS320F2802)?

I really enjoyed all your videos
I just want to know if it is possiblle to use an arduino uno as a programmer for an stm32 microcontroller
Thanks in advance

i like it . thanks for your hard work

how did you learn this without videos like this? Any chance you could provide a roadmap?

How do we know this programer is Arduino as isp?

The quality of the content you are producing speaks for the effort you are putting in. Incredible job!

clearly explained all aspects of programming the arduino via bootloader & via an isp programmer.. excellent! thanks mitch..

How to write your own bootloader? I really appreciate a video talking about this (I think it's gonna be several videos but anyway, I eould really like to do almost all things on my own as you have shown on your videos) thank you.

I need to ask the one dislike person (whyyyyyyyyyyyyyyy !!)

It gives me error invalid signature 0xffffff for atmega 328p U , i tried like so many things but still cant be able to burn the bootloader in this chip through arduino, please need some help with this

Excellent videos in beautiful clear English! You always make all signal connections after your target has been powered. Something ever die doing it this way? Maybe make the connections first and turn on the power last?

Damn, I've learned quite a bit with this series

I accidentally corrupted bootloader of nano, tried to make that work as before using another nano. But eventually fails. But this video makes quite lots of info, great work.👍🏻

Why is the led in the programmer also blinking in the last example?

Great work thank you, i was wondering why you did not use the ICSP pins using jumper wires ? rather than the standard pins !

Disregard Mitchel I got it working with the avr-gcc toolchain.

Great video. I’ve been looking for an explanation like this for days because most videos just show you how to use a programmer but don’t explain what’s going on. You’re very good at explaining things. Keep up the great work.

Great video. Keep working

Great Job! Thank you!

Blah blah blah blah killed me 😂. I just use an ftdi friend

Thank you for the video!
