Is it possible to read out flash memory in AVR?
The answer is that yes indeed, it is possible– with a couple of exceptions that are worth mentioning. And on occasion, it’s even very useful. Reading out the flash memory is straightforward with an AVR ISP programmer, such as the USBtinyISP, using avrdude from the command line.
Can you read and write flash from Arduino?
You can, for example, read and write the full flash contents of an Arduino device that has both the Arduino bootloader and a program on top of that. Then, deploying an additional copy of that program becomes as simple as executing a single command to write the flash file.
Can a makefile be used to write flash?
For production programming, the single avrdude statement can set the fuse bytes and also write the flash, or a makefile can be written to give multiple avrdude statements, for sequencing the order of writing flash and fuse and/or lock bits.

Which is the best software for AVR development?
There are easy installers available for Mac ( Crosspack) and Windows ( MHV AVR Tools) that include this software, along with the other open source tools for AVR development. Linux packages for AVR development are also available.
What do you need to flash burn AVR files?
Just connect the output of the programmer (6 lines VCC, GND, RESET, SCK, MOSI, MISO) to the respective pins of the unpowered target atmega8 (which you placed in the breadboard). The final thing needed is a program (burner tool) for flash burning!
What is an are value in AVR Studio?
An R-value is a quantity of some kind (not necessarily numerical), usually the result of evaluating an expression, but also a constant, such as ‘5’ or the string “Hello, World! “. An L-value is a something that a program can assign an R-value to, such as a named variable, or a raw memory or port address.
Where can I find the avrdude command line?
You can read more about the avrdude command line options in the avrdude documentation, or in the tutorial at Adafruit.
