A cross compiler is a compiler capable of creating executable code for a platform other than the one on which the compiler is running. Cross compiler tools are used to generate executables forembedded system or multiple platforms. It is used to compile for a platform upon which it is not feasible to do the compiling, like microcontrollers that don't support an operating system. It has become more common to use this tool for paravirtualization where a system may have one or more platforms in use.
Here I bring to you two softwares which are used for cross compiling and burning an hex file into your ATMEL microcontroller. Please notice that it can be only compatible with ATMEL microcontrollers. So below is the link of to download both the CVAVR compiler. You can use any compatible hex burner. I used EHT Hex File Burner. But as it's a proprietary software I can't upload it.
