How are binaries loaded in the default Arduino bootloader through USB? - arduino

I got a desktop program that interfaces with an Arduino.
I need to be sure the correct program, either Processing or pre-compiled AVR binary is loaded as part of my handshake routine with the Arduino.
What are the steps for initializing the download/new program loading procedure on the Arduino Uno R3 with default bootloader?
I want to recreate the upload command found in the IDE.

In the Arduino IDE do this:
Plug the Uno into your computer.
File > Preferences > Show verbose output during: > compilation(uncheck), upload (check) > OK
Select the correct board from the Tools > Board menu
Select the correct port from the Tools > Port menu
Sketch > Upload
After the upload completes resize the black console window at the bottom of the Arduino IDE window and scroll up to the top. You will see the exact AVRDUDE command that was used to upload to the Arduino.
You can copy and adapt that command as needed for use with your program.

Arduino code uploads fine, however avrdude output is not able to read / verify memory

Purchased some clone Arduino nanos a while ago and finally got to working with them.
Of the 3 i worked with, 2 of them upload and verify fine.
The third is able to upload (code functions properly), however it fails to read flash data.
this is required to post pastebin
Here is the output from a clone that worked:

Here is the output from the one with the issue:

What I've done so far:
Reflashed bootloader from working Arduino as ISP
CH340 driver installed
Used (old) bootloader when uploading
Tested on both Linux and OSX
Any suggestions or insight would be much appreciated.
If you have a working UNO or similar board, you could try uploading the bootloader using the Arduino IDE (https://www.arduino.cc/en/Main/Software), and see if you get different results. Sorry, I'm not familiar with using avrdude.
The link on sparkfun gives really good instructions on how to accomplish this task. Scroll about half-way down to where it says Upload Arduino as ISP https://learn.sparkfun.com/tutorials/installing-an-arduino-bootloader/all
Basically, you connect the UNO to your target as shown in the link, then select ArduinoISP in the examples menu, select the COM port and board, and upload the sketch. Then you select your target board in tools, and select Programmer, Arduino as ISP in tools, and finally, Burn Bootloader in tools.
I've had 100% success burning blank Atmega chips using this method.

ESP8266 + Arduino Uno + ESP8266WIFI lib

I'm having a problem with ESP8266 in programming part.
I'm using Arduino Uno and have thousand times run programs.
It's has been my second day in completing my esp8266 simple fully function circuit
My current problem is :
ESPwifi library has many error even I download it from official github source code
So, I decided to use WIFIESP library and it stuck at TIMEOUT/NO WIFI/NO MAC ADDRESS
I cannot use pin 0 & 1 because a wire stuck in it.
I have search everywhere to solve my problem even tough needs alternative ways I will at least doesn't required NEW HARDWARE.
Reupdate : 08:18 PM 4.3.19
I just want steps without need AT firmware & able to post data to websites
I don't want extra boards EXCEPT:
Arduino UNO
ESP8266-01 (small one with 8 pin)
Windows 10 with arduino IDE latest version
I'm not sure what your real problem is, but here is my solutions:
In case you haven't install the esp8266 boards for the arduino IDE yet, then you should install it first. The installation instructions is documented on GitHub. Here is the snippet to install ESP8266 boards on Arduino IDE:
Start Arduino and open Preferences window.
Enter http://arduino.esp8266.com/stable/package_esp8266com_index.json into Additional Board Manager URLs field. You can add multiple URLs, separating them with commas.
Open Boards Manager from Tools > Board menu and install esp8266 platform (and don't forget to select your ESP8266 board from Tools > Board menu after installation).
ESP Libraries needs Arduino Core Library to work. If you haven't install the board yet, then you will get many errors.
hope this help.

Should I reinstall nodemcu firmware if I uploaded a arduino sketch?

I have a nodemcu v3 and I'm trying some basic stuff
I installed the esp8266 board in Arduino IDE and then I uploaded a blink example.
But now I'm trying to upload Lua code using ESPLorer but I doesn't work properly. I press in open and set the baud rate to 115200 but I just get some infinite Chinese letters.
Should I reinstall the firmare or something?
There is a very good answers at https://stackoverflow.com/a/43509569/131929 and https://stackoverflow.com/a/47510019/131929.
Should I reinstall the firmare or something?
First you should make up your mind whether you want to conveniently program in Lua or whether you want to stick with Arduino (running on the NodeMCU-clone board). It is an either-or question. Flashing on of them to the module will erase the respective other.
And no, in case you want to use the NodeMCU firmware, you should not use those outdates binaries from 2015. Build a recent version conveniently in the cloud: https://nodemcu.readthedocs.io/en/latest/en/build/.
P.S. if you're interested why I call yours a clone board you may want to read https://frightanic.com/iot/comparison-of-esp8266-nodemcu-development-boards/ from yours truly.
You must erase the flash of your NodeMCU before a new upload. If you ignore that, your software don't run appropriately. To do that, I'm using esptool:
python esptool.py --port COM9: erase_flash
In that example COM9: is the name of my USB/serial interface.
After that you can flash for example your ESP8266 with that line of code to add a boot part:
python esptool.py --port COM9: write_flash -fm dout 0x00000 boot_v1.5.bin
Use the preview line of code and adapt it to upload other parts of the map of the flash memory.

Arduino Mega2560 can't be programmed repeatedly using avrdude

I have a sketch for a mega2560 board that I can upload successfully using the Arduino IDE using the upload button but I would prefer to use a script using avrdude. The only problem is if I try to run avrdude more than once to flash the board it get's a stk500v2_ReceivedMessage(): timeout. It doesn't happen every time but enough. The only way the avrdude seems to work again is if I update the same sketch using the Arduino IDE.
I was having trouble finding what the Arduino IDE does to upload a file but all the settings I could find suggest that avrdude is doing it the same way.
Verbose compilation and upload can be enabled in Arduino IDE Settings:
File->Preferences->Show verbose output during: [] compilation [x] upload.
It will show complete commands used for upload and the avrdude should be same or you can use the same avrdude.exe. You should see something like:
C:\arduino\hardware\tools\avr/bin/avrdude -CC:\arduino\hardware\tools\avr/etc/avrdude.conf -v -V -patmega2560 -cwiring -PCOM17 -b115200 -D -Uflash:w:C:\Users\kiiv\AppData\Local\Temp\build658cdf44885ca2a8676f164a933c092f.tmp/MAX7219_4x4x4.ino.hex:i
BTW: I've just started with PlatformIO CLI (command line tool) and I'm loving it.
PlatformIO IDE didn't work well for me, as I'm using czech keyboard layout and keystrokes prevents me to write all essential characters like []{}#& without switching it to english one.

Cannot upload program to Atmega8

Hi I try to upload program (on Atmega8) with I created in Arduino using throught Chinese programmator and I have an error
avrdude warning cannot set sck period. please check for usbasp firmware update
In Arduino I set up:
Tools->programmer->USBasp
Tools->Board->Arduino NG or older w/Atmega8
to upload the hex code I use the command File->Upload Using Programmer
Wher I try to upload thtought khazama program everything ok.
You're getting that warning because the programmer isn't accepting the speed set command from AVRDUDE. This was an option added to later versions of the USBasp firmware to support slow devices (e.g., ones running off a watch crystal).
However, the programmer you're using (according to that description) auto-adjusts its speed to an appropriate value, so there's no need for AVRDUDE to adjust it in the first place.
And in the end, a warning is still just a warning. Unless you see actual errors generated by AVRDUDE the program should have been uploaded to the chip properly regardless.
